Write your reply.

assistant: The load is purely resistive, unlike dynamic drivers which have reactive
elements which do require current as you describe.   It is
electrostatics which are largely capacitive.  The stable non-frequency
dependent load of a ribbon is another mark on the positive side of the
list.  Ribbon drivers need not be low in efficiency.   The Carver 60"
long version is 90 db with an active xover.  This is probably a bit
over the average for all types of drivers.  The foil on diaphragm
versions, like the Carvers, can have multiple turns of ribbon in the
gap.   The non-diaphragm versions usually have one turn in the gap and
are inefficient.  The Carver drivers are extremely durable compared to
other kinds of drivers.   With the ribbon in air, the thermal limits
are very high.   It is said to take 500 watts with no difficulty.  The
diaphragm is made of a very stable material which does not change
dimensions with temperature.

assistant: I recently had that just thing happen to me (and the others at a Darrell
McCall concert I was a guest at). The sound system had double-loaded 18"'s in
"W" cabinets for low-end response and the soundman was giving 'em a work-out.
He was more used to doing tejano music, which is heavier on the low-frequency
than country.  Even Darrell complained about it.  During the break between
the set between the live shows, the sound man put on some tejano stuff
("Marcarena" and others, and even - Yuck!  "Achy Breaky Heart") Only thing we
can figure out is he must have been ready to go home, cause he was trying his
darnedest to run everyone out of there.  There were several people
(especially some of the older folks) who left. Thank goodness there wasn't
any seating directly in front of the cabinets, at least for 75 feet or so
(until the end of the dance floor), or someone would have thought there was a
tornado a brewin' (from all the air being pushed from those cabinets! I stood
there in front of 'em for about 10 seconds to feel for myself.).
It was totally unnecessary, and the club manager eventually made his way over
to the sound board to tell him to "turn it down!"
Darrell told the band fronting him, "Let's go back on so he will shut that
stuff off!"

   that Gordon Gilbert spake unto Matt Ion:
Unless Carver's doing something completely off the wall (which wouldn't be
entirely out of the realm of possibility :) this is completely against the
way electrostatic speakers work.  They are to condenser microphones as
"regular" speakers are to dynamic microphones.
From the _Handbook for Sound Engineers_, section 16.4.3 "Electrostatic
Loudspeakers":
"An electrostatic loudspeaker consists of a diaphragm made of two pieces of
metalic foil separated by a sheet of dielectric .... An electrostatic speaker
is nothing more than a capacitor; the internal capacitance is in the order of
0.0025uF from electrode to electrode.  Thus, the impedance presented by the
loudspeaker to the output of the amplifier falls off at a constant rate of
6dB/octave as the frequency is increased."
In essence, a large capacitor which is then hung vertically within the
framework of the speaker.  A polarizing voltage is then applied to the foils,
and the signal voltage fed to it to generate a fluctuation.  Again, like a
condenser mic in reverse.
Complex crossovers always complicate the load :-)

user: You are replying to Phil Roberts about "Sub Transducers".

Write your reply.

assistant: The sub transducers you saw in Damarks catalog are indeed used in
Home Theater applications. In fact there is an outfit that has a "high end"
transducer that was recently reviewed briefly in Home Theater magazine. The
pair cost over a grand ($1,000 US) and were attached to 12 inch plexiglass
disks that bolted or screwed to floor joists or furniture.
        The reviewer chuckled at the idea before he tried them, but in the
end really liked the effect. I would imagine they would be especially
effective in a small listening area with smaller or lesser powered systems or
for systems lacking big subs. The Damark price seems a lot closer to what I
would pay to have something "vibrate my butt for effect" than the high-end
models.
        The Home Theater reviewer said that he could no longer take exception
with critics that accused him of doing his critical listening for reviews
with his rear end. 8-) Really cute review though.

i need some help
a few questions .
1. Is there a limit to how many speakers you can run off one amp ?
2. If there is a limit. would a larger amp be the answer ? as then
   there would be more power ?
3. On my home stereo, I have the normal speakers which I guess are 8
   ohms, I have added two moer speakers which are 4 ohm. Can this
   damage the system at all ? It is a very cheap system and I don't
   think it would really matter.
4. If you want to put a lot of speakers on one amp, is it better to
   get an amp with more channels ? Say 4 or 6 channels ?
   Is this a way to get more speakers onto an amp ?
please help if you can

In a nutshell, ohms are a units of measurement of electrical resistance (or
more correctly in this case, impedance).  There's lots of good reading out
there on the subject, so I won't take up bandwidth by rehashing much more
than that here.
Basically, your amp isn't designed to have a load of less than four ohms
across the outputs.  The A and B speaker terminals are actually just wired in
parallel, I would guess with a switch or switches to select which ones are
used, if not both.
When connecting speakers in parallel, the total load they present to the amp
is reduced; if both are the same impedance (say, eight ohms), then the total
load is cut in half (to four ohms).  Thus, you could have the amp driving one
set of four-ohm speakers, or two sets of eight-ohm speakers in parallel... or
any other combination whose total load does not go below four ohms.
Car speakers are typically rated as four ohms; putting them in parallel with
the eight-ohm speakers would give you an average impedance of 2.7 ohms.  You
could do it as long as you don't turn the amp up very much; on the whole, I'd
recommend against it.

I have another question.  When your amp clips, how can you tell?  I mean, on
my dad's stereo, it was easy to tell because it has two lights that say
"Clipping."  Hahah, not too hard to figure out, but on my cheap lil amp, it
has nothing.  So do i just listen for audio distortion?  But then how can I
tell if it's the amp clipping or the speakers being overloaded?

Write your reply.

assistant: Hahahha, talking about computer speakers, I was using the lil white Labtecs.
You know, the ones that come with the SoundBlaster or you can buy for like 10
bucks.  At that time, I didn't really care much about computer sound until I
got into games and stuff.  Then I saw my friend's comp system and really
wanted one.  Hahha, so i asked my dad and he dug up a Onkyo reciever from his
closet somewhere and I took the speakers from my old car taht I wrecked
(another story) and put them in and had big sound from my computer.  Then my
dad bought me a pair of Polk bookshelves and I put them in, but then I tried
them on my dad's system for the surrounds and I thought they were much more
suited there because my dad had these really cheapy rear spkrs and the Polks
really improved the sound there.  I just connected the old rear from my dad's
system to my computer.  Now, I get pretty decent stereo sound and am happy.
I'd rather have this then waste 100 bucks on a set of "computer" speakers
just so that they will be white and I can put them next to my monitor (which
I don't want to do anyway).  They probably wont even sound as good, even with
a subwoofer.  Well, that's just my story.

assistant: It depends.  If you run speakers connected in parallel the load
on will decrease, but if you run them in series the load will increase.
I guess it would be theoretically possible to run speakers in enough
series/parallel connections as to keep the load within a respectable
level and keep adding speakers as well.
        Ah yes, the power consideration.  Even if you did manage to keep
the load within limits, the number of speakers would effectively
decrease the amount of power each one saw.  This could be likened to
poking holes in a water hose.  The first hole will see maximum pressure,
but each new one you add will descrease the amount pressure.  So, yes
you would eventually need an amp with more power.

Well, one of the guys ain't answering yet, but I wanted to respond.
Ain't no such thing as a generic subwoofer plan, since every sub is
different, it may require a different cabinet with more volume, port
size, etc., etc., than the generic speaker you plan to use. A 12" is
small potatoes for a home theatre subwoofer. When you purchase the
speaker and have (hopefully) the Theile paramaters, then you might be
able to come up with a cabinet design with those values to plug into a
speaker box program or doing the math by hand.

assistant: And so it came to pass, on 01-13-97 20:35,
   that Shayn Wilesmith spake unto All :
Yes and no.  As long as you keep the total load within the amp's tolerance
range, you can (theoretically) add as many speakers as you want, in
parallel/series combinations.  In reality, the available power must still be
divided up between the speakers, and eventually the law of diminishing
returns takes over.
There's also the interaction you'll get between multiple drivers and their
crossovers; the effects may be undesireable.
That would only allow you a little more leeway before the effects of the
extra speakers are negated by the splitting of power.  It would be better to
simply add MORE amps (as in, one for each pair of speakers).
If it's a cheap system, it probably doesn't have the capacity to handle small
loads.  An eight-ohm and four-ohm speaker in parallel gives a total impedance
of about 2.7 ohms, which is probably well below a "cheap system's"
capabilities.
Yes, or as I said, just get more amps (which is, in essence, the same
thing... a six-channel amp is the equivalent of three stereo amps sharing one
power supply).
