I would appreciate some info from those who own or have long term knowledge
of these speakers.
I'm planning to use a pair of Quad IIs as the main amp (I do also have a
Quad 33/303 setup but for now I want to use the Quad IIs).
My main listening room is about 14x17 feet. Without re-arranging the room
(and probably moving the fireplace and/or the patio doors) the speakers will
have to fit near the back wall facing the patio doors. Problem: the door
into the room is at that end and so the speakers will need to be within 2
(maybe 3) feet of that back wall or I will have to climb over one to get
into the room..
Which ESLs would be best in this situation? One american review by someone
who really seemed to know his audio from his elbow (and his Claude Debussy
from his Miles Davis) says the ESL57s are happier nearer the back wall than
the ESL63s BUT another review by someone else who also seems to be very
knowledgeable says EXACTLY the opposite.
Advice please before I go completely mad and buy a pair of each.
Thanks,
John Smith.
By a pair of each?, good idea!, then you can try both of them. I'd go
for the 63's However the only thing I'd question is the ability of the
303 or the 2's to drive them. You IMHO really need something a bit more
meaty to drive them. I've got an Audiolab 8000 power amp driving mine
and their fine with that. I reckon that the 57's have a lower output and
have a distinctive sweet spot for listening, but their mid range is very
good indeed.
You could perhaps make up some absorber frames filled with rockwool and
covered with fabric in order to minimise reflections from the rear of
the 63's as in fact they do radiate equally well to the rear, so your
point is a valid one.
I really reckon the only way to see you happy on this is to try both if
possible but having used the 57's and 63's I'd opt for the latter these
days.
However whichever you go for make sure they are performing to spec.
ESL's do suffer from leaking panels and are a bit like having a
substation in your living room especially when the weather is a tad
humid, so make sure they don't crack or hiss when in use and ask to see
any service history they have. QUAD service do still look after these
and I have had mine seen to there a few times over some 20 years or so
and have had new "stockings" and wood work etc, as well as a panel or
two, but they still are by far and away the most accurate neutral
speakers on the planet, so wise choice and enjoy the music which is
*exactly* what I do with mine:))..

Now I went through all this a short while ago and actually got as far as
demoing some prospective buys. Your experience to date is not unlike mine.
There are some Quad fanatics in this world that will berate you into
believing these things are the definitive bench mark of speaker design.
Maybe, maybe not, as it comes down to personal preference and the type of
music you listen to. Example - one friend of mine (who actually had 3 sets
of ESL57s in various states of disrepair and only one set working) said to
me Quote: "I am only buying and listening to female vocals now." Somewhat
restrictive I think but then I noticed a trend with others as well so this
was not in isolation. Undeterred I still ventured on. After all these are
"The World's best speaker - right?" Yeah for female vocals with no bass and
limited SPL levels and *IF* you do try and "Arc them up" (now I know where
this term comes from) the panels arc out and "Hey Presto" more repair bills.

First I will put my flame suit on (slip) IMHO these speakers are currently
more suited to the more technically adept out there that love tinkering with
gear and know how to repair these things. Apparently the answer is to stack
them (so twice the expense) and have dedicated rooms to put them in with
music that suits. I have read where they are used in HT rooms but being a
confirmed sceptic "I would like to see that." My main worry with these is
the maintainance side and I look as these more like a vintage car that needs
that "special care". Being in the UK you will have a lot more opportunity
finding repaireres and parts so that will make it easier.

I don't think you were looking for what I just said but I thought you would

BTW In all my research into these no one *seems* interested in the new Quad
988s (which are essentially a Quad 63) and they never come up in
conversation.
Now a plug for a local bloke http://www.eraudio.com.au/ I ended up talking
to this guy at his workshop and very nearly bought a set. At the price I
thought I couldn't go wrong. That was until I put on some Pink Floyd/Dire
Straights and told him they were just like Quads with no bass and he then
told me his speakers were not for me. Since then I have demoed (at home)
Martin Logan hybrids as well - still not impressed :-( BTW you will need
to see this part of his site as well
http://www.eraudio.com.au/Kits/kits.html
So my final conclusion is "ESL technology is not for me at this stage" but
they do have nice mids and silky highs. I ended up buying full range floor
standing cone speakers. Now if we could just get a nice ribbon tweeter
................ ;-)
This is a long way to get to what I really want to say to you. Are you
really, really sure you want some antiquated Quad speakers with their quirks
and fragile disposition? Did I mention they don't like dust or high
humidity either ;-)
BTW there will be many die hard Quad owners who will now refute all of this.
I am just relaying *my* experience and thoughts.

** ESL57s need to be mounted up on something sturdy - the three
supplied legs are a joke. I used two small tables about 15 inches high (the
sort with four, square section, steel legs) and bolted each '57 to one with
right angle brackets. A bit of packing allowed the speakers to be pointed
right at ear level when seated in the ideal listening position. The
speakers sound much better this way and are far less likely to topple over
( four legs good - three legs baaaaad ).
If you added small furniture castor wheels to such a support then moving
the 57s out of the way when not in use would be very easy. Remember - the
ideal listening distance is 7 to 10 feet, regardless of the back wall
proximity issue.
IME, keep the rear and side walls well away - by 6 feet if possible for
best results.

It's quite easy to prevent an ESL57 arcing these days.
Just use an amp rated at less than 75w into 8ohms,
or play a test CD with a 0dB signal on it and measure the
output voltage. Don't turn it up past 24v.
As for the bass - it's not like a typical boombox. It doesn't
play its own drone to accompany the melody but it is accurate
and surprisingly good. A subwoofer is always an option if you want more.
I don't think I've ever needed to give mine more than 10v, though I
wouldn't use them for a party.

The 303, however, had active both current and voltage limiting built into
the power supply.
I've read that decent conventional amps should be more like 25-30 watts
max.

To e-mail, change noise into sound.
** The 303's PSU was voltage regulated - a common practice in 1968. The
supply rail was set at + 67 volts - there was no current limiting in the
PSU. So the maximum unloaded swing possible was about +/- 33 volts.
A 45 watt @ 8 ohms amplifier is rated to swing +/- 27 volts into that
oad - with an unregulated PSU that might typically increase to +/- 35
volts unloaded.
The highest impedance an ESL 57 reaches is 30 ohms at 100 Hz.
So 40 to 45 watts rated amp at 8 ohms is likely to be quite safe.
BTW:
I ran my ESL 57s with an 85 watt @ 8 ohms amp for 20 years and never arced
them.

Absolutely. If you're doing the live male voice versus the same via a

I've ever heard will come close to the original ESL for this.

Actually, this is rubbish. Just take the grilles off '63s, and they
are superior in every way to the '57. As is the off-the-shelf 989.

That's what a couple of my customers say.
Most ppl with '63 say they are better than '57.
The '57 you might buy could be different ages, bought singly
at first, and thus have aged differently, and since this model
of Quad speaker could be up to 48 years old, they could be at the end of their
service life,
and will need a major and costly re-furbish.
In Oz, John Hall of Melbourne charges about aud $1,000+ for
re-panneling a single '57.
I would be hesitabt to ever buy a pair, unless they were aud $200.
'63 are more likely to be in good original condition, and to have been purchased
as a pair,
and if I ever see a pair for aud $1,000, I might be tempted to buy them.
They were about aud $5,000 in 1982, new, or about equivalent
to aud $25,000 now.
It all makes me want to aquire an ESL kit, since I have some natural ability

Em, probably "meaningless" I'd say. :-) I like the 57's and 63's a great
deal, However I don't think it means anything to describe any real speakers
as the "world's best" with no qualifications at all. Speakers are designed
for specific applications. Hence speakers that might be the "best" for one
person may not be for someone else.

But if the 57's are in decent condition then a 303 or II won't drive them
with voltages that should do any damage. This was how/why PJW designed the
57's and the 303/II's to work together. He ensured current and voltage
limiting and band roll-off in the amp that should ensure they are quite
'safe' with 57's.
Should not be a consideration with 63's as they can take more than 57's,
and have their own protection systems.
> >

Yet PJW designed them for people who simply love music. And as pointed out
above if they are in decent condition and used with the amps he intended,
there should be no 'technical' problems. The limitations are essentially in
peak levels and low bass, so this is matter of if the results suit the
user.

That may depend what the 'question' was... :-)
I suspect that many people used them for years without stacking, and I
suspect that some people still do.

Not sure who you asked. :-) I have a pair of 988's as well as a pair of
63's, and I like both models. If you check back on uk.rec.audio you may
find they *have* appeared in conversations here in the past...

Well, with the 988's I ended up buying a sub to go with them. But I remain
quite happy with the 63's without that.

Funnily enough, I've not encountered such problems in 30-odd years of using
57's, 63's, and 988's... :-) As indicated earlier, all depends on the
user requirements, though.

I can't recall the relative efficiencies, but I would that thought that a
303 or II would drive 63's at least as well as 57's. If anything the 63's
are an easier load. You might not be able to produce the peak levels some
other amp can produce with the 63's, but then you probably could not get
that from the 57's either. :-)

If at all possible have the speakers further into the room. :-) I also
have a door in the 'hi fi room' in the corner behind one speaker. I just
have the speaker well into the room.
> Which ESLs would be best in this situation?
The problem is that it will depend on your taste and the specific details
of the room acoustics, etc, etc. FWIW I preferred the 63's to the 57's, and
I now also like the 988's. All used in quite small rooms.
The condition of second-hand speakers will also be important. Particularly
for 57's which will be older, and had no protection circuitry, so may well
have been misused.
If you avoid early issues, the 63 is also a much easier load for the amp
than the 57.

I'd say that both of them really need to be at least 3ft from the wall
behind, and preferrably more.

My vote would be for 63's. But your taste/circumstances may not be the same
as mine.

The manual says 33v peak, which is 68 watts into 8 ohms, so if you have
an unregulated PSU, 45 watts is about right.

Unless you use tone controls, the advice stands.
Digital sources go so loud and no more, unlike cartridges which can

** So one can "calibrate" the CD or DVD input as you say - but that it is
far from a foolproof solution. Unless the amp's output stage is incapable
of exceeding the safe peak voltage then sooner or later it will do so. This
may be due to some minor accident with the interconnects, another item being
powered up or down producing a loud crack or thump, the introduction of a
new item into the system or a fault developing in the amp that creates loud
noises. It only takes one overvoltage event to do the trick.
Have you have not learnt that Murphy's Law is not to be trifled with ??

to time. In combination with an oversized amp it is an accident just

I didn't state the facts wrong; I didn't say what '63 s/h prices are now,
or what price the '988 are.
I merely said that what cost about $5,000 in the early 1980's
was equal to spending $25,000 now.
I recall ESL63 were retailed at $4,800 in 1982.
I bought a Teac cassette deck for $400 back them; and that was like spending
$2000 now. Quite an absurd amount of money, but I made
around $400 a week easily in 1982.
Now I make less than that.
The cost of living and the value of my house has all risen about 5 times.

If you can hold your nose about the snake oil aspects, there's a good
place to start at:
http://www.cardas.com/content.php?area=insights&content_id=26&pagestring=Room+Setup
It seems to work pretty well for dipoles, although designed for
omni's. I've had very good results in lotsa situations using this as a
starting point, and letting the owner deal with WAF.
Personally, like you, I go for nearfield listening.
Good fortune,

So why the '63 then?

** Even Peter Walker never claimed the ESL63 was necessarily a better
*sounding* speaker than the old 57.
The 63 was, however, a technically improved design - it was much easier
to manufacture, far more consistent sample to sample, protected itself from
overpowering, presented a benign load to the amplifier, handled more power,
operated down to a lower frequency limit, had wider dispersion of high
frequencies - and was styled to blend into modern decors.
Those already familiar with the sound of 57s found the 63s generally very
similar - with more deep bass and a bit less high frequency energy. The
ability to use *any* amplifier ( valve or SS) up to 100 wpc more quite
safely was a huge bonus - especially to all the thousands of 405 owners.

Everyone should get the Quad expert here, Phil Allison, to
tell you how *HE* went about buying second hand Quad 63s.
Yes he tried very hard to get sequential frame numbers only
to find out later how there was 6dB difference in SPLs. He
then had to sue the second hand dealer and it took him
nearly 12 months to get his money back.
So "Caveat Emptor" and "try before you buy". Two very good
bits of advice.

If I had the spare $$$$$$ I would go straight out and buy a pair of
ESL57, if only to be able to see if my own creations were as good,
and knowing perhaps I might be able to sell them on at not a large loss
if I was unhappy.
But what I have not experienced for myself I cannot hold as being true for me.
I rarely gamble.
I do recall the change in sound when i went from
generic asian made drivers to SEAS drivers, and both lots of speakers had
received enormous attention to silencing the enclosures
and optimizing the crossover design.
The north euro drivers were just plain clearer sounding.
And for fine strings large cones are usually deadly, and multiple
close mounted well made smaller cones have a better chance...
The only big recollection that ESL could be sonically marvellous was
at an audiophile meeting in Sydney on a sunday in one of the shops
where they demoed a pair of 1.2 m high Martin Logans, and which were
powered by a solid state amp.
The massed strings in the opera Carmen were I thought far better than I had
ever heard before.
They seemed to have the right sort of sizzle and warmth rather than
the coldness and smear of many systems.
( what would a decent tube have done with these speakers? )
But in other demos of '57 speakers I have heard since, I was not so swept away at all,
and I remain slightly skeptical.
Then I have met a few folks who think Quad ESLs are all crap,
and Acustat is the only thing, another dude far preferred Stax, which I got to listen
to,
but I wondered what the fuss was about.
Recently a client of mine recently brought a well stuffed '57 to me,
and the quote from a guy in Melbourne, John Hall, did seem high.
But his price for repairing a bass panel is aud $350,
and there is some real and skilled work involved.
John is a lot cheaper than germans and their panel costs.
He is half the price of a guy in Sydney who fixes Quads.
Another client of mine with stacked Quads has very high regard for John so
I left my original client to proceed with John directly as he finds the funds;
I didn't want to be caught being a middleman.
The vast majority of ppl I deal with don't like a speaker repair bill for a grand
when there are so many other expenses, school fees, house and car payments,
and all the rest.
I'd be very wary about removing grilles from ESLs.
My last cat died from old age, she knew where the best sweetzone was,
and I think she had a definate preference for classical....
I have a house mate and she is allergic to cats, so I get by without an animal.
Animals are very pleasant, but i prefer the company of people.

** ???????
All my friends thought my ES 57s sounded incredibly good - so much so
that several of them bought pairs, one bought two pairs and stacked them.
I suppose you are alluding to the slightly wider dispersion angle of the
63s - which is there but does not make the stereo "sweet spot" any
bigger than the principles of acoustics permits.

You are an idiot, which should be stated when reporting anything you

They bloody weren't. I had a pair which were *very* shoddily built,
but easily fixable in those days. However, since it's physically a
very simple design, pair matching is indeed not a big problem.

No one in their right mind would use them professionally - they have a
ragged frequency response, no bass, and very limited loudness. BTW, no
ESL57 is half a century old, it first went on sale in 1966 - you're
too used to writing pot-boiler fiction.
>John Smith should choose between the Quad ESL57 and the ESL63 on the sound

Or Martin-Logan, or Acoustat, or any one of a number of excellent
modern moving-coil designs which do have the same clarity (if not the
same dispersion pattern). Let us not forget that the '63 is *not* a
dipole, it's a simulated point source.

What do you think is one of the main improvements on the 988/9? You
really are an ignorant clown. Many top people in the audio industry,
including the redoubtable ARA of SME, use 'naked' 63s, as many people
do regard this as the finest speaker ever made, unlike it's cruder
predecessor. It's certainly possible to rig a safety screen which will
not affect the sound so badly as does the original grille.

And it's revealing that Walker had already started work on the '63
three years before the '57 even went on sale in 1966. An interesting
coincidence is the price of the '57 when it was launched - £57.

*** Well, where does one start?
Phil is surely not shy when it comes to voicing an opinion. Usually a bit
more colourfully than most would prefer and with that personal touch that
only my Philip has.
He reckons he invented a new type of ammeter?? I tried to tell him he was a
silly boy as some other old fart had done this already, but I have to give
him credit where credit is due - he did make up some fancy box of tricks.
Got no idea what it's suppose to do but it looks technical.
In about 1996 he designed a pocket oscillator that is sold as a DIY kit that
is marketed for about AU$23.00. He got diddled and doesn't get anything for
it.
In audio circles Phil is infamous for buggering up a pair of second-hand
Quad ESL63s and earned the handle "Quad Boy". He said the dealer was a
shonk. No one believes him but what is a mum to do? He had some ESL57s but
he got rid of them. I think one is been used as a spark guard in front of
an open fire place in an inner city suburb.
He is also known for his "expertise" in "fixing / buggering up" toasters and
therefore is well known in aus.electronics as "Toaster Boy". Well, back
when he was a boy he tried getting a bit of burning crumpet out of the
toaster with a fork. Went off with a big blue flash, an awful bang and
blacked out one side of the street.
Above all, Phil is known mostly in several newsgroups for his inability to
carry on a rational discussion or debate on any subject without introducing
a personal insult (or five) and colouring his posts with the odd bit of
profanity. I honestly don't know where he gets this sort of behaviour from.
The doctor said we should all show him a bit of compassion and tolerance for
his Tourette's syndrome. I often wonder if the shock from the toaster had
anything to do with that?
I wish my Philip would take up a nice hobby like a girlfriend for instance.
It would stop from abusing himself and that blow up doll he keeps under the
bed with the plastic urinal. Besides it would give all you nice folk on the
newsgroups a bit of a break from his frustrations. But as my Philip is now
in his late 50's I don't hold much hope for him on the romance side. He's a
bit too set in his ways to change now. :(

Erm... word of caution here. The early issues of ESL63's actually have a
quite 'difficult' load characteristic. Later issues are somewhat better due
to revised circuitry. I would not personally describe early issues of the
63's as 'presenting a benign load' as people might find that misleading.

I was talking about the '57.

*Why does the sun lighten our hair, but darken our skin?
Anyone would think I suggested you had not a friend in the world Phil
by implying subtly that buyers of Quad 57 were the nutter-friendless types
because the image was only available to one person.
But it wasn't my intention to portray buyers in any particularly poor light.
But I have heard a litany of claims from my generation ...
"Daddy, why were you not there for us..."
"Mummy, why didn't you understand me..."
and "My dad didn't seem to have any real friends..."
All mostly BS of course.
In fact what Phil says about the ESL imaging from Quad is fairly correct, ie,
the image is very precise, and the sense of being there is very real.
But unfortunately, and i make no apologies for the "buts" i refer to,
many folks think such pin-point accurate imaging is entirely unatural, because
like
last time I heard some '57, when one moves 1 foot
side to side, a singer in the centre appears to whiz across the stage in the
opposite? direction.
This does not occur at a concert, where the image is about as real as could be
hoped for, and any greater sense
of sound stage and performer placement is quite unreal, and therefore need not
be reproduced, as long as that sense "of being in a theatre and not at home"
was clearly preserved in a replay.
People say, " I listen to my system and I can point to where
mu aunt is signing in her choir"
Yeah?
Anyone believe that?
Blind folded, i reckon they'd have buckley's chance of knowing where
their aunt Mildred was positioned at a concert, unless she was
a solo special and up front.
Somewhere out in front of us is all most people really know
where things are, but many try to posture by saying thay percieve
more than someone else.
Some do, some don't.
But there is a difference surely between the soundstage produced
by an orchestra and scattered artists compared to sound from
two speakers 8 feet apart.
An image or illusion is a fragile creation, hence movement
when listening to a good image destroys the image, because it is but just an
image,
not like the real waves one hears at a concert.
But with some systems, some movement of ourselves does not produce the same
amount
of false artist movement experienced with '57, yet I have heard ppl say the
imaging is fine.
Are such systems worse, or better? I thought all that depended on
subjective personal preferences.

WTF has that to do with professional use, you ignorant cretin?

http://www.quad-hifi.co.uk/history2.htm
The Quad Electrostatic was on sale in 1957 - and I have numerous original
Quad brochures from that time which clearly show that it was on sale in
1957.
It also appears in the HiFi Year Book of 1958 , this being the earliest one
I have. I don't know where your 1966 date came from but it isn't correct.
OK, I can't hardly argue with the Hi-Fi Yearbook, although that jibes
with the Quad site, and shows inconsistency between the naming of 57,
63, and 98x.
Ohhhhh, boogggger! :-(

Well, apart from those before and after the power supply mods, Walker said
they were. And I've had wildly varying serial numbers sent back for
overhaul and had them come back sounding the same. And *he* told me
matching pairs referred to the woodwork.
YMMV.

The design process started in 1948 - the first prototype displayed in 1955
and the famous ESL 57 was on sale in 1957.
Quad called it the "Quad Electrostatic Speaker" - the name ESL57 was
applied by others later.
The speaker pre-dates the era of stereo.

** There is no shock risk from the diaphragms of an ESL 63 or 57 - the
DC supply voltage is fed from a very high impedance source and the Mylar
film has a coating that is only very weakly conductive.
> These have significant signal voltage, but *not* Kilojolts.
** The middle unit's stator panels of the ESL63 or 57 *ARE* capable of
delivering a serious shock - since the AC drive voltage ranges up into
the kilovolt region and the source impedance from the step up transformers
is quite low.
The stators are coated with a paint that provides a measure of insulation
but there are exposed metal contact areas too.
There is good reason to be wary.

No worries.......just thought that in the interests of accuracy etc. etc.
Wouldn't want to try & re-write history would we :).
The ESL '57 was in production from 1957 to 1985
The ESL'63 was manufactured from 1981 to 1999
(The '63 bit related to the year in which serious development work started )

You can say that again!! You will find it unrecogniseable. Try and get hold
of Peter Hitchens book "The Abolition of Britain" as some preparatory
reading for the shock you will experience if you have anything other than
childhood memories of the place.
I left England in 1983 and have been in NZ for 12 years. I went back last
March and found it so GHASTLY I couldn't wait to get on a plane and come
home again. I arrived Saturday morning and flew out on the following
Thursday. I won't go again.
Hope you have a good trip nonetheless.

1) In the early reviews. For example, in MC's reviews in 'Hi Fi Choice'
number 26, 1981. This shows a dip down to about 3 Ohms in the 10-15kHz
region, and also at 50Hz and below. He comments in that review that the 63
isn't as easy a load as Quad implied. Rated the load in his summary as
"fairly difficult". IIRC In another article he also pointed out that at LF the
early 63's had an impedance that was level dependent.
2) I do have an early pair which I bought new. I did measure them at the
time and got results that seemed consistent with the reviews
Above said, it is fair enough that what is 'difficult' is a matter of
circumstances. However I would not personally rate a speaker that dips down
to about 3 Ohms as described above as a 'benign load'. So a word of caution
seems appropriate to me. Particularly in the context of amps like the 303
or some other amps which may become current limited by the impedance dips
and hence not enable the full output implied by a given voltage ability.
> > Later issues are somewhat better due to revised circuitry.
> ** See above.
See above. :-)
See also the service manuals for the ESL63s. If you examine the circuitry
you will see the changes from one issue to another. IIRC some later reviews
also show impedances that don't dip so low and are less reactive around the
dips.

Alternatively, if you check the references I cite you may find that what I
said is based on evidence. :-)
It may be the case that you have only seen, or recall, the details of the
later issues of ESL63 boards, etc. For the reasons outlined above these
can show an easier impedance.
> Maybe you think the ESL57 was released in 1966 too ???????
Afraid I can't recall when it first went on sale. The precise date may
be listed in KK's book on QUAD, but I'm afraid my copy of that is
currently shelved at work by the anechoic chamber, so I can't check it
immediately.
My copy of the 1957 "Hi Fi Yearbook" has an article on the ESL which
describes it in terms like "when such units eventually become available."
However the speaker was reviewed by Ralph West in the November 1957
issue of Hi Fi News and that indicates it was on sale. Hence I assume
that the yearbook was published early in the year, and the 'ESL57' went
on sale sometime during 1957. However as I say, I can't recall a date,
and I haven't checked in detail.
Slainte,
Jim

Considering each and every one was quality checked after repair I don't
find it unsupported? Have you ever visited the Quad factory and had
speakers repaired while you waited? Because I have, on more than one
occasion, when they offered that service.

The speaker is featured in an article in the 1957 yearbook, and described
in terms that indicated that at the time the article was written it was not
yet one sale. I think the yearbooks were written and published 'early' so
as to have a long life as being for the 'current' year.
The first review of the ESL57 I'm aware of at the moment is in the November
1957 issue of HFN, and that implies it was then on sale.

I've now had a chance to have a brief look at the material on the above
website. What I've seen seems mostly to duplicate or copy material I
already have. However it was useful for me in two ways. One was that the
'late' 63 circuit diagram does remind me of that for the 988 rather than
the circuit for the 'early' 63. However the diagrams seem to agree with
those I have, and confirm my understanding that the circuit, and the input
impedance, of the 63 did change from early to later issues.
The second point was from seeing the excerpts from TA's review of the 63
in HFN (Oct 1981 issue as the second part of his review has most of the
measured results). I could not recall off-hand where I'd seen the
measurements of the level-dependency of the impedance of (some?) of the
63's. However the excerpt on the above website reminded me that this was
in TA's review. Apart from that, though, his results seem broadly
consistent with MC's which I referenced in a previous posting. However it
may be worth noting that TA's impedance plots look like a hand or
flexicurve drawing through some data, whereas the data shown by MC seems
to be a copy of a pen-chart plot, so may be more precise by avoiding
redrawing errors.
If we refer back to the OP's comments:

The relevant point here is the wish to use either a 303 or a pair of II's
as the power amps. The 63 has an impedance that drops below 4 Ohms at some
frequencies and maybe down to about 3 Ohms in some board issues in some
circumstances. Taking the 303 and an example: If the power amp which it is
intended to use can only provide the order of 3 A then it means that this
may at times mean the signal becomes current limited to be around 12V or
less.
This is somewhat below the 30V implied by what the 303 is nominally able to
deliver into higher impedance loads. The real values won't be exactly as
described here, but the point is that the amps the OP proposed to use might
not find the 63 - particularly in some issues - a benign load in this
respect. Afraid I can't recall the values for the II, but can check these
if someone wishes. However I suspect that is also limited in its current
capability and might have a similar effect to take into account.
The above does not mean you can't use 63's with a 303 or II's quite
happily. Depends on the levels, etc, required by the user. I'd expect the
amps to be quite stable and work fine within their current/voltage limits.
But some other amp may well be able to make better use of the 63's in terms
of exploiting their power handling and not being restricted by the
impedance dips. Also the output impedances of the 303 or II may well
interact with the speaker impedance to slightly alter the response. Again,
depends on the user, etc, if this matters or not.

It's still a good place to be if you're out in the country, but with
easy access to the cities. I live about half an hour from Birmingham,
and an hour and a half from Central London, but I get hawks, pheasants

Check Hi-Fi Choice issues 26, 31 and 36, in each of which the
impedance curve is printed. It's not printed in Issue 46 of 1986, but
the same difficulty of drive is noted by Colloms.

The shape is similar, Colloms detects a deeper dip around 10kHz. Take
it up with Moir and Colloms.
My main location is even more rural. Within a 2hr drive of the city

The graph in the URL shows an impedance that remains above 4 ohms across the
whole audio band.
There were NO changes to circuit values in the path from speaker terminals
to the two input transformer primaries - including the 1989 version.
Tests published in ETI magazine by Louis Challis and Associates in Nov.
1982 of ESL63, s/n 8552 states:
" LF minimum at 10 Hz = 4.0 ohms ,
HF minimum at 10 kHz = 5.4 ohms. "
> Taking the 303 and an example:
** The 303 will deliver 40 watts or more ( 16 volts rms) at any
frequency from 45 Hz to 5 kHz into an ESL63. It is not ideal for the '63
since it is not built to operate into 4 ohms - but there is no real
problem either.

** You are still using a false claim you have NOT proved !!!
The input impedance of the ESL63 is ABOVE 4 ohms across the working range
!!
It is NOTHING like the ESL 57 that drops to 0.3 ohms at DC !!
The ESL 63 is **benign** since it will not cause damage to a direct
coupled SS amp like the ESL 57 can.
There was NO change in the ESL 63 load impedance as FALSELY asserted by YOU
.

The curve here shows the impedance is at or above 5 ohms from 80 Hz to 8
Hz - and just dipping to 4 ohms at 20 Hz.
Published data from ETI magazine, Nov 1982, states the LF min as 4.0 ohms at
10 Hz and the HF min as 5.4 ohms at 10kHz.
In comparison to the ESL 57, and many other speakers - this is a very benign
load characteristic.

" was released needs to learn to FUCKING SHUT UP !!!!!

Come on?
Everyone here needs to know your *TRUE* level of total
incompetence and at the same time have a really jolly, good
old laugh at your expense.
Or perhaps you would prefer I told the story? BTW I
promise it will be the non-contradictory and facts omitted
version ;-)

You really do need to try some new medication.

Sure I do, now that the original misunderstanding has been cleared up.
Some of us learn and move on, others just scream ever more loudly.

Jim doesn't make false claims - unlike you.

Jim's posts are always polite and well argued, and are never pompous.
It would be well if you posted in a similar manner rather than
insulting him. His contributions are far more valuable than your
rants.
Please learn the distinction between reasoned disagreement and
unreasoned ranting.
