And so it came to pass, on 12-13-96 19:52,
   that T Owen spake unto Matt Ion:
 TO> It is the bandwidth itself, not how much of it we allow to pass through 
the chain,
 TO> that matters. Digital equipment simply needs to have better resoloution.
As always, a chain is only as strong as its proverbial weakest link...
 TO>> AL-III?  Never heard of that one. 
 MI>> Carver "Amazing Loudspeakers", their 7-foot-tall ribbon jobs. Talk 
about comparing
 MI>> apples and oranges :-)
 TO> Ah, I have heard lots of praise for the Carver ribbon drivers, though I 
have never
 TO> heard a pair. 7 feet tall? What is the driver compliment with those? I 
assume cone
 TO> drivers for the low frequencies, ribbons for the mids and highs....How 
many (if so),
 TO> and placed how? Take care.
Gordon has corrected me: only about 6 feet tall.  In any case, I believe 
(it's been a while since I looked) that they are comprised of only the ribbon 
driver, and a (relatively small) woofer (one may want to add a subwoofer to 
extend the lows).  That's one of the (theoretical) advantages of ribbon 
speakers: the extremely light elements reproduce highs 
very well, while the sheer size of the moving surface extends the lows quite 
well.
Of course, there are always trade-offs.  A near-ideal design for reporoducing 
sound, but 
they must be extremely large, the ribbons are relatively very fragile, 
they're hugely 
inefficient, and being an entirely capacitive load, require an amp that can 
deliver 
*LOTS* of current.
