driving stacking Quad ESLs in parallel
micha...@my-deja.com
57s with one amplifier. The Quads would be stacked, two per left
channel, two per right channel. I'm aware the impedance of paralleled
units will fall sharply above 8 kHz, but in this case the amplifier
(and subsequently the Quads) will not see frequencies in this range as
I will be using an active crossover to present only 100 Hz - 8 kHz to
them (subwoofers and tweeters will handle the frequency extremes).
Anyone out there have an opinion or experience in this area?

I used a QUAD 405-II limited to 50 wpc (internal adjustment)
that drove stacked ESL57s quite decently---from 80-3000,with a
crossover.Finding a compatible sub(subs)and tweeters is important.
Feel free,if you have any questions.Raanan

I'm thinking Pyramid T-1 ribbon tweeters (I already have) above 8 kHz,
and subs below 100 Hz (don't have yet). Paralleled Quads will dip to
0.9 ohms impedance just above 8 kHz - a challenging demand for an amp,
hence my thinking in sending all higher frequencies to the Pyramids.
That sound like a good solution to you?

Excellent idea! Build a dedicated stand for the stacked 57s
so that you can alter the angles that each pair are pointed-as phase
problems are bound to occur in any room and phase problems will muddy
the sound.Being able to adjust the relative angles will enable you to
minimize the unwanted interaction.Play it by ear.
In addition,mount this dedicated stand on spikes-very very
important-makes A WORLD of difference.I just couldn't believe my ears
the first time I mounted one stand on spikes and compared to the
unspiked stand in mono!What amplification will you be using on the
stacked Quads?You might find it easier to write me at rey...@excite.com
