How do you go about reconing a speaker?
mark
myself? Do I need to buy specialized equipment? If so is it expensive? Can I
recone it as a jbl 2242 or better speaker model? In others can I upgrade a
speaker by reconing?
Thanks

yes anything can be done yourself, but it is not worth the trouble of
sourceing parts, making mistakes, buying new parts, haveing no warrentte on
your work
tell us where you are and perhaps someone can recommend a reconer
also look in the back of the trade magizes like PSN and LS for ads from
reconers

yes you can buy a kit and you can buy the glue.
Can I do it myself?
yes, but there are several tricks to learn. like cleaning the gap (where the
voice coil fits into) with sticky tape to remove metal debries.
Do I need to buy specialized equipment?
not really... a power amp and an audio oscillator that goes down to about 1
hZ can help test it after you are done. the guys who do this all day
'should' work under a ventilation hood so they don't have to breath glue
fumes.
If so is it expensive?
not as expensive as a whole new speaker. but the cost of JBL recone kits is
shocking.

in some cases a heaver or slightly larger voice coil can be built into a
recone. or a 4 ohm coil instead of 8 ohm. this is rare however and only
done at a customers request, usually in response to a specific problem.
Mark, i have worked in shops which have recone departments, i have seen it
done yet i still send speakers in rather then do it myself. its like playing
a guitar well... until you have had lots of practice it isn't as easy as it
looks.

You question is: who can do it. You can probably learn to do it, but the
real question is whether you can get good at it. It takes special gifts
to get good at reconing.

Sometimes. I don't know the models you ask about. I don't think you have
ther patience to do it well enough, you seem to be a rushed nature to
me. No offense intended.
Find something with cheaper spareparts for practicing. JBL traditionally
requires precision.

Interesting comment Peter.
I've never re-coned a 'loudspeaker' before, although one of my colleagues
has ( several times ) - but I did once take one apart and re-wind the voice
coil !
Ok - I was a kid - and it was economically sensible for me to do so - but it
was an excellent example of how to practice ! It worked fine after too !
Replacing diaphragms in MF / HF drivers is usually very easy due to auto
centring features. The worst trouble I ever had was with earlyish RCF units
where you had to 'hand centre' with sinewave input. YIKES !!!

Re-coning a speaker requires skill. Some have it - some don't.

** Lots of self centring diaphragms don't - even those from companies
like JBL and Emilar.
There are often spots that rub against the magnet structure or the height
is wrong allowing the phase plug to contact the dome - this needs spacer
rings to fix. You can only be sure the fit is good by using a sine
generator and trying a few frequencies around 400 Hz with a few watts of
power.

** Jands are the exclusive IMPORTER and hence ONLY Aussie supplier of
genuine JBL parts. The pricing for JBL in Aussie is SET by agreement with
the JBL company in the USA - especially the cost of cones and repairs.
The repair cost is set way high to help justify the new speaker price
structure.
My info from several sources is that JBL cone kits arrive in Aussie at
little or no cost to Jands - so the ( out of warranty) repair business is
very profitable for them.

I was at a job interview at Nilfisk-Advance in december, they only
manufacture a small parts of their product line in Denmark now, much is
being made by LG. I got the impression from the description that LG has
assembly lines like Volkswagen (building two brands on the same line in
Spain) with the difference that they make then some Nilfisk, then some
Siemens, then some Hoover .... who knows, they might even mix, then a
Nilfisk, then a Siemens, then a Hoover. Most vacuum cleaners are real

> Just asking, Graham
It looks as if all the JBL worth being interested in today are
descendants of products in that 1971 pro brochure on their site - oh,
there is the Ti5000, it is only broken by having the titaniumn tweeter,
oh, 14", 8", 5", tweeter ... almost as if Duelund had built it ... oh,
and all but the tweeter from that catalouge, hmm - imo it must be a
Pierce, but we'll never know that. And the Butt horns ... and the 075
tweeter, so good that it seems to have been discontinued almost
instantly, it is from around 1979, I don't think it lived much longer
than the single system it was fitted to ex works, it would certainly be
the proper tweeter for the 5000's and not that fiZZlyTwiZZly it comes
with.
Reminds me, my LE14's are approaching 10 years surround age (that's when
the surrounds disintegrated last time, and the good reconer in Denmark
will close shop this year .... hmmm .... and foam probably still is the
only option, I had preferred to roll them back to the black corrugated
súrround and live with the slight loss of deep bass and retuning the
boxes.
Mostly but not strictly: that catalouge lists all real JBL components,
at least in ancestor form. The appear to have stopped listening when
they started measuring.
But of course, there is nothing new in audio ... the Fostex T825 was
designed in 1953, and almost all products on the market are some that
could be found in some version in Briggs "Loudspeakers", the Manger
Schallwandler and the Heill elemenet are the only new stuff since that
book was written that I have heard of, and that book too is from the
1950'ties.

Hi Phil
Jands are also the JBL distributor in NZ but we have a couple of very
good speaker repair shops who source parts directly from overseas,
either, directly from manufacturers , or through buying houses. Our
situation is slightly different to OZ in that our law allows parallel
importing. Your comment on the pricing agreements are valid but NZ is a
different market subject to different agreements.
Also, at least one of the repair shops have been round longer than
Jands, and have historically dealt with JBL and other manufacturers
directly. One in particular does Jands NZ warrantee work also.
So, NZ$80 (US$~50) might seem low but it is entirely possible.

Only the thickest Kiwi would leave NZ for Australia, hence the lowest
IQ would be gone so the average of remaining would be higher.
But at the same time even the thickest Kiwi would have a higher IQ
than any aussie so s/he would drag up their average IQ.
Seems a pretty simple, satirical, hypothesis to me although I could be
completely wrong as I've no idea who Muldoon is and I'm lurking on the
other side of the world.

> I want to recone an 18" jbl 2240. Are there kits I can buy.
No, the manufacturer of the recone kits will only sell to "authorized
repair centers". You could become an authorized repair center if you go
thru a training course, and agree to the $2000 minimum first order of
repair parts. They want to keep the repair club very exclusive, you see.
>Can I do
> it myself? Do I need to buy specialized equipment?
It is possible to do it yourself, but hard. It requires basically five
parts to recone a speaker, the cone, the spider, the voice coil, the
surround, the dust cap. Oh and maybe replacement terminals if the old ones
are broken or damaged. Oh and you need several types of special glue made
for speakers, one high-heat type for the voice coil, one type for the
spider and surround, and one type for the dust cap. It generally runs
about $100 per gallon, and yes, you need all three types. Sometimes you
need a fourth type to coat the entire cone with after it's all glued back
together.
All you do is tear apart the old cone and pull it all out. Clean off all
the old glue, and the clean out the magnet gap with sticky doublesided
tape. Then you place the new voice coil in the gap and use special plastic
strips that look like lighting gels for par cans to center the voice coil
and hold it in place while you glue the cone on. The kit I had was very
clever, the strips were different colors depending on how thick they were,
.5mm was yellow, the .75mm was red, the 1mm was blue, etc.
Once you have the voice coil in place you put the spider on and glue it,
then when that is dry put the cone and surround in place and glue it.
Then remove all your spacer strips and glue the dust cover in place. Also
there are cardboard strips that go over the surround in case the speaker is
back mounted in a cabinet.
Very simple, very easy. But just make sure that your voice coil is spaced
perfectly, according to specs, both horizontally and vertically or the
speaker will fail almost immediately and you have accomplished nothing.
> Can I recone it as a jbl 2242 or better speaker model? In
> others can I upgrade a speaker by reconing?
Sometimes you can change from a 4 ohm version to 8 ohm version of the same
speaker, but beyond that there is not much you can do as all the speakers
have different magnets and use a totally different recone kit. The voice
coil for a different speaker probably wouldn't even fit in the gap of your
magnet.
So in essence, if you want to spend $2000 to recone your speaker, and are
prepared to do it three or four times until you get it right, sure you can
recone it yourself! :^)
Have fun!
Sanders
mirco tolerances that if you are not experienced with, you will destroy
the $$$ you spent on a recone kit. Have it done by a professional so if
there are problems, they have to pay for the mistakes and not you.
