Agreed.
The curve makes perfect sense when you realize that the controller is
tryinbg to compensate for a crappy speaker that rolls off drastically
above 12 KHz and below 80 Hz.

--and explains why they worked so nicely for us (without Bose-O-Matic EQ, with 800 Watts each) as midranges (250 - 2500 Hz) for c. 1981 pub dates.
You're giving Bose too much credit! ;-)
Bass rolloff must be -3 dB at about 100 Hz, and treble rolloff is -3 dB at 7
KHz.
If you compare these to a good unequalized monitor, such as an EV SX500, you
find that the unequalized monitor is -3 dB at around 75 Hz and 15 KHz. The
big difference is at the high end!
http://www.hedcom.fi/files/hedcom/audio_pdf/EV_Sx500_EDS.pdf figure one (EV
site seems to be down at the moment).
The weak spot of the 802 is probabably more in the treble where it takes
about 15 dB to do 12 KHz. Pushing a drum kit with cymbals through this could
be a recipie for disaster. Just guessing, but I'd suppose that the system
designers were from an era where drum kits were acoustical instruments and
there was no such thing as an electronic drum set or they weren't in
widespread use.
I'd guess that compared to the modern Bose stick system, the 802 is a model
of high dynamic range and robust bass performance. However, it might do
better at the high end.

Again I say, Put up or Shut up. Time after time, you tell us you have data
that supports your positions and refutes others. Either provide it or
point us at a URL that contains it. You're acting like a small child who
doesn't like what he's told and can't do anything about it except whine.
Steve Hawkins
St Davey is so lost to his own little world that when we hit him with
the truths and facts he has no ability to face his lacking technical
knowledge so he simple refuse to acknowledge it.
trying to get through to St. Davey is like trying to teach a pig to
dance
the hard we try the more time we waste and the pig just doesn't get it
George
hmmmm....pigs eventually become bacon. Anybody ever thought about
contacting Bose and suggesting that they should take a look at how they're
being represented here. Unless, of course, you folks keep him around for
the entertainment factor.
Steve Hawkins
Well, what amazes me but doesn't surprise me is that you tell him that he's
wrong, but don't say why. Arny has admittedly guessed... he made that
clear. Would you prefer he spoke with certainty about something he is
guessing about?
I guess so, because then he would have a valid reason to trash me, instead
of playing the innuendo card.
I am sure he is well on his way twards either unemployment or
enshrinment at Bose
I have never seen anyone ever ask for St Daveys "unique:" insights, yet
he continues to offer up his devine "wisdom"
I don't think even he believes half the stuuf he says
he just says it to flap his gums
but "I" don't keep him, I only see the litter he writes when others drag
it into thier posts, around AAMOF the group on the whole would be better
off without his half formed informantion or his" Scripture according to
Farmingham " bullshit
George
guessing about or has no experiance in
it makes no dffrence to me
either way his "advice" is pure egotistical shit
he is a boil that needs lancing
George
Particle, (that is a very odd name btw)
You can answer your own question very easily by going to google and
researching threads with Bose and Dave Andrews. You will quickly see a
pattern develop. Although I rarely post I have been reading this group for
several years and I can see why Dave has about given up on posting technical
data. It will not matter how technically accurate the data is, it will not
matter that it is all based on undeniable physics. The only thing that
matters is that he is associated with Bose and to several people, who like
to be vocal about it, he cannot possibly be right because of that, and
therefore everything he says is to make Bose look good or to make money. The
typical canned response would go something on the order of "Don't listen to
St. Dave because he is nothing but a Bose shill and has to say these
things". But I would suspect that if he worked for virtually any other
company (EV, Telex, A&H, hell even Peavey) it would be an entirely different
story. But you can do the research yourself and you can come to your own
conclusions.
Les
The fact is St dave posts bullshit
it is not bose or mackie we dislike it is the lies they tgell in order
to sell product
you don't see us slamming EAW cause EAW suff works
if Bose worked we would support it
Bose sells cheap ass shit to stupid people, and some of us here, me
included, take them to task for it.
If I came here and said the musos do not need individual monitor mixes,
audio is something that only I could possibly understand, and that the
fossil records were placed in the earth 10,000 years ago to test ones
faith
you should rightly question anything else I might say
But I don't say stuff like this, St. Davey does and by default anything
else he says is suspect, esp in relation to securing more sales for his
employeer.

Dear Steve,
It seems you're desparate for a pen pal. I have posted on this several times
in the past, so since you seem to be sincerely interested, we'll just do this
in small steps.
How 'bout we start at the input side.
What does the IEC measured curve look like for average musical audio content?
In case you need to look it up, IEC stands for the International
Electrotechnical Commission, and the chart shows the audio band applicable to
human hearing with a curve reflecting the intensity of each of the various
portions of the frequency spectrum. That means it graphically represents how
much LF, HF and midrange is in the signal for all music content expressed as an
averaged curve.
Get back to me on this one, and then we'll go to step #2. Please -- no
cheating by going back to all the posts I have made on this topic over the past
5 years.
I'm all ears, or rather, eyes. I would love to know about the
processing and speaker characteristics of the 802. I've never used
them.
Thanks,
Rupert

Rupert,
Thanks for the post. Steve Hawkins' post came before yours, and I already
began a process of responding with him. So depending on how well he does his
homework, we'll go through this one step at a time.
Generally speaking, when I unload the entire wagon in one "swell foop" I just
hear derision from the folks -- most of whom are technologically speaking "lost
in the weeds". So we'll let 'ole Steve provide some of the background material
and then let him think through the steps one by one. Hopefully, he won't go
MIA and let down the entire class.
Go Steve! We're countin' on ya'.

> SX500................
Hmmm - unusual choice of reference there Arny.
Had some reports of SX500s causing amp protection to cut in yrs back and
investigated. Used to cause problems in the mid range around 1.5 - 2 kHz IIRC.
A truly horribly complicated internal crossover with astoning phase angles
presented to the amplifier.
The SX500 crossover also includes a fair bit of *passive EQ* !
I also *loathe* the sound of the things - harsh - strident - 'shouty'.
Just my tuppence.
Graham
Stated impedance is about 6 ohms, which IME is low for a stage monitor.
> A truly horribly complicated internal crossover with astoning phase

The tweeter is a constant directivity horn, which means that it must have
loads of equalization. It's not that complex though, just a straight line
> The SX500 crossover also includes a fair bit of *passive EQ* !
That CD horn!

course you do, but since you don't have any, you posted the above. As

We're going to develop the "data" and the "rationale" behind Bose controller

Poor Dave. He doesn't seem to understand that I wasn't the poster asking
for the info. You were asking the wrong person. No points for you, my
lad. BTW, I probably know as much or than you do about it. I built test
equipment that makes those measurements. Try actually answering people's
questions with facts instead of ridiculing and talking down to them.
People will like you, really they will.

So at your request, I am in the process of working you through a step by step
understanding of the controller EQ, it's rationale --i.e. the philosophy behind
it and the role that it plays in conjunction with the 4.5" drivers that are
used in several of our products, including the 802 and 402.
Since my previous responses have been met with resistance, and I have been
chided by you and others (unfairly, but who's counting) for not having anything
to support my statements, we are now going to go through this one step at a
time with your full participation. I cannot go through an explanation without
being certain you are onboard for every step in the process. So please, just
answer the questions that I toss out one at a time in succeeding posts, and
we'll make short shrift of this -- and all will understand this without me
having to go through it again every other month. If you're the only one that
gets it, you can then at least answer wrongheaded posts. You don't need to
like the product to at least know what goes into it and why.
Actually I was objecting for the original poster, but you know that. I'm
still waiting for those cost and sales numbers for the Bose system. That's
the subject I've been interested in since we started this discussion.
Why don't you just do your lecture as a single document and post it on the
website. Then we can all refer to it and mine it for the data we're
interested in. Might turn out to be a publishable work when you're done.

Okay, please make sure the thread name stays the same. When you say
published, do you mean on usenet or is there a Bose Marketing App
available? Is the app online somehwere?

Steve, Bose could care less about how they're perceived in a public
forum full of guys who will never purchase their products. It doesn't
make marketing sense for them to take the time and give this forum a
look-see.

George, it is abolutely, morally wrong to use someone's beliefs to call
into question their technical prowess. I think you owe an apology for
that one.
I would never presume to question your understanding of audio just
because you happen to believe that the earth is very old, or that Jesus
wasn't God, or that the Koran is the Chosen Truth, or even that all
things are part of the same spirit. Get my drift?

I heard a pair of these and thought they sounded like glass as well, so
I had the club owner turn them inward so they didn't bounce sound off
the mirrors on each side of stage. Much less glassy sounding then.

sooooo. what does it all mean... you are a born again Bose Audio Engineer?
Or an Allah Mackie deciple? I don't really care.... this bose rant is some
fun reading but until Jesus himself posts on the topic I think we leave him
(or her... or it) out of the discussion.
I'll get it started again.... Bose sucks.... St.Dave sayeth: Bose is great,
Bose is good, Dave thanks Bose for his food.... A-men! Everyone... A-men!
Dammit, give me a big 901 A-men!
Now, back to the rant boys.....
-Sax
for the record I did not make any refrence to christanity or faith
all I did was point out St Daveys outright rejection of proven hard
science as a reason to doubt what ever he says,
it does not matter what religion he holds dear
to reject evolution is just not possible in the face of the research
and documentation that exists proving it,
and again i have to point out I specifical do not directly address
HUMAN evolution. but evolution as it exists in plants and many animal
life forms that evolution can be easily observed in a lab.
I did not say he was always wrong but only that his thinking process is
so flawed that it casts a desrved shadow suspect on his logic and
motives for his posts
when one only posts here in threads that pertain to thier employeers
reputation and always defending thier employers point of view ,
regardless of how baseless it may be, makes Davey a shill and
propagandist for Bose
as well as some one who can post endlessly while never addressing a
question or really say anything at all
when he runs out of "cheap laughs" he resorts to petty insults and
withdraws into his own refuge of overblown ego, talking to anyone who
challenges him in a condesending tone, alluding that only he can
understand audio and everyone else is just a unwashed and barefoot on
the playground he is king of.

Just because we don't buy, doesn't mean we don't talk outside of this
forum. Word of mouth is the most powerful form of communication there is
because you're usually hearing it from someone you know and trust.
I like the Bose PAS/L1 as a system for a solo, acoustic performer. I won't
buy one because of it's cost. It just doesn't have an extra K-buck's worth
of difference IMHO.
