The indispensible Phil Allison tells us:

*******
The Quad ESL57 input transformer has an overall turns ratio of 292:1.

The bias voltage on the bass panels is 6.2kV and they require 18 kV
volts
p-p of audio to reach full output.

The bias voltage on the mid/high panel is 1.5 kV and requires 6 kV p-p
of
audio to reach full output.

The Quad ESL63 has a bias voltage of 5.2 kV on the panels and requires
16 kV
p-p of audio to reach full output.


To achieve this feat:

The ESL57 uses a single, modest size, C-core transformer to provide the
two
levels of audio drive.

The ESL63 uses a pair of modest size, C- core transformers to provide
the
audio drive.

These are born-dangerous truth-telling loudspeakers of very great
refinement. But behind the engaging smile, it's all high tension! I am
proud to own Quad speakers. I have never heard another speaker that
gives so much longterm satisfaction.

stuff on Quads.

Yes, and? You do this to see your pseudonym on the screen? This reminds
me of the scene in Alice, where the jurors are writing their names lest
they forget them by the end of the trial...

It is not certain what Mr. McCoy is, or what it believes its name to
be, so a little self-supplied reassurance must be critical to the
maintenance of its fantasies.

Worthless Wiecky whined:

Yes, and?

Jute did not say the words you falsely attribute to him, Worthless.

What's your latest plot with Lyin' Bwian? Are you going to abet his
conspiracies to rip people off, or are you satisfied with indulging his
insatiable desire to slander and calumniate?

I doubt that Phil ever told such a whopper.
The audio voltage never exceeds the diaphragm voltage.

No good deed ever goes unpunished.

Hi RATs!

I liked the Quads I heard at my friend's house. They were very nice. I
do not recall if he had hair on his chest. I do clearly recall none of
his girlfriends had any noticeable hair, on their chests.

The Quads worked great for many months (years?) until he force fed them
a 20 Hz square wave. Two blue flashes - silence. Audio is fun, but,
destruct testing gets expensive.

Objectivists have their agenda, I have mine.

Happy Ears!
Al

working overtime. You are one ignorant bit of snot, aren't you?

Worthless Wiecky learns how to include quoted text in his ****-missives.

One step at a time, even for a psychopath like you, Worthless.

BTW, how do you justify collaborating with Bwian McFraudster while setting
yourself up as an arbiter of morality? Aside from your obvious mental
illness, of course.

Exception:

http://sound.westhost.com/project105.htm

polarization is speced at 1.5 KV, and maximum drive is 2.5 KV RMS

Other authority:

http://www.geocities.com/quad_esl63/...atic/esl63.jpg

Gives the power supply voltage as 5.25 KV.


The turns ratio of ESL speakers is usually in the 80-100:1 range. The
maximum RMS input of the ESL-63 is given by some as 10 volts RMS. This would
lead to no more than about 1 KV.
