I was thinking of buying these, can anyone suggest some suitable gold
infused 200 Amp speaker wire with low oxygen content?

3/0 copper is the only wire you will find that can handle 200 amps, and
it's about 1/2 inch in diameter.

I think you mean 200 watts.

Oh, that site is an absolute gem. To wit:

"To provide you this we put a bi-wiring gold-plated back panel with
jumper bar connectors who can be removes."

"ULR was founded in 1986 and have been involve with industrial
vibrations and acoustic control equipment ..."

"We use our special multi frequency liztwire. We do our own wires. They
are impossible to find in anyplace. Those wires are important because
they conduct more efficiently the current to your drivers. The electrons
(the negative electric particle of an atom) in the current do not
propagate the same way when they are induce by different frequency. More
the frequency is high, more those electrons stay on the surface of the
conductors. It’s call a liztwire effect or skin effect. We can’t explain
all here because we would need many pages but this subject is well
documented in physics."


(Well, obviously English is not their first language. But some of the
howlers here transcend any language barriers!)

No you need full 200 amp capacity wiring for the peak demands for the odd
picosecond during use, for the best transcription

Though I know you're kidding, I sincerely hope you're kidding about buying
them.

For what the speaker costs, and the profit they make on it, they could
easily pay a native-English-speaking copywriter to create effective
advertising. That they don't, shows they don't care what kind of image they
present. I would not normally buy products from such a company.

I loved the line about the effectiveness of biwiring in controlling back-EMF
had been proved by lenz [sic]! (Lenz has been dead for some years.) In fact,
biwiring should have no effect on the back-EMF "seen" by the amplfier.

"But remember what it does when you block a bicycle pump at one side and you
lower the handle. It gets more difficult to compress air. Well all other
speakers have that problem!"

No, they don't. Planar dipoles don't.

If Tesla were alive, he'd probably sue for having his name attached to this
product.

I wish JGH were still alive, so I could call him and we could read the ad
together, and laugh our heads off.

If you have US$13K to spend on a speaker, you can buy something much
better...

I was actually looking for some good speakers when I came across the ad,
but seriously though, the whole audio sector is so overhyped, I know a
couple of guys developing speakers, and the way they go on, its more
magic than physics. I'd like to see a pro review of those speakers, they
may well sound great, but so far I've not found anything. The Quads look
good but again way out of my price range.

Not in the case of electrostatic or "orthodynamic" speakers. When properly
executed, such drivers are superior to cone drivers.


I'd like to see a pro review of those speakers, they may well sound

again way out of my price range.


Given that they use SEAS drivers, they're probably very good. But there are
better speakers for the same or less money.


I see nothing wrong with a "serious" listener spending $15K for a pair of
speakers -- that's what you spend on a car these days. But most people don't
see it that way.

If $15K is outside your budget, listen to the less-expensive Martin-Logan
hybrid electrostatics. They're not "cheap", but you're getting a really fine
speaker at a "reasonable" price.

If you don't want 'stats, listen to B&W. They're among the few "neutral"
dynamic speakers that don't sound insipid. If I didn't own planar speakers,
I would own B&Ws. (At one time, I did.)

Alternatively, take a look at some of the kitted "assemble it
yourself" speaker systems available from (e.g.) Madisound and
Zalytron. Many of them are available either as parts-only kits (build
the cabinets yourself from plans), or with cabinets pre-built (just
finish the cabinets and install and wire the components). There are
some very good kits available... essentially equivalent to the
reference designs from the driver manufacturers themselves.

One of the advantages of such kits is that you can build a rigid, tightly
braced, really /dead/ enclosure, which is never found in modestly priced
"box" speakers. You can also experiment with such things as painting the
cabinet with Nextel.

There used to be a joke that /everybody else/ knew more about using KEF's
drivers than KEF did. This was generally true.

Yup.

I designed and built my own cabinets, rather than using a fully-
kitted design, as I wanted to fit them into a specific space in
my living room. Double-thick front bezel with a deadening compound
between the two layers, lots of internal bracing, and a thorough
glopping of the interior with Shur-Stick Permanent Patch 100. These
boxes are *dead*... they go "thuck" rather than "boing" if you tap them.

I've always wondered (and dreamed) of a speaker cabinet made of granite or
soapstone. With the right drivers, I'll bet they'd sound great.

It was made from glazed tile sewer pipe. That was the DrainPipe 8
speaker.
http://www.audioxpress.com/magsdirx/ax/addenda/media/weems_drainpipe8.pdf
My father and I built one (not two as this was in the daze before
stereo). It think I was 15 or 16 years old at the time. I vaguely
recall that it sounded great, but my mother had aesthetic objections.
The sound also coupled nicely to the floor and neighbors downstairs
also voiced their objections. The only part I really remember was
watching someone haul off the monster to who knows where.

And then I found this...

I think David Weems did something such as
this in one of his speaker books from the
80s. If I recall, he used the chimney flues
which were rectangular and had rounded
corners. He cut the flue in half, making an
angled cut, so each piece had a slanted
front baffel, which was made of wood.


From what I can remember, it made a great
cabinet. I think it was Weems.


My memory served me well. He used 9"x13"x24" chimney flue tile, and cut
it in two, by making an angled cut, using a masonry blade attached to a
skil saw.

You might want to look at the higher end Paradigm speakers. Some of
their under $2k speakers sounded better than a $20k speaker we used to
sell at an upscale audio salon. Chuck

Best speakers I've heard were some prototype electrostatics built by a
friend in the hi-fi biz. Was hoping he'd go into production on them, but
failing that, anyone here have electrostatics that they'd recommend?

Well, there's probably a trade-off there (especially with regard to
granite). Ideally, you'd like the resonant frequency of a cabinet to
lie well outside the frequency range excited by the driver(s)
inside... either below, or above. It's also beneficial if the cabinet
is relatively "dead" (low Q).

Granite is quite heavy (lowers the resonant frequency), but also quite
stiff (raises it)... I'm not sure what the resulting resonant
frequency of a typical cabinet made of granite would be. I suspect
that its Q probably isn't all that low.

Stiffening a speaker cabinet with internal bracing will usually raise the
resonant frequency (the increased stiffness outweighs the added mass).

Now, a laminate composed of two or more layers of stone, separated by
a very lossy damping compound (a "constrained layer" arrangement)
could be quite interesting.

Unwieldy, though... it's bothersome to have to drive a forklift into
your living room to position the speakers properly. Tough on the
hardwood floors, and even worse for the carpeting :-)
