[net.audio] Speaker survey, and a question

jeff@tesla.UUCP (Jeff Frey) (10/30/83)

I recently asked for opinions on top-quality loudspeakers.  The consensus
of replies was that the KEF 105.2 is THE speaker to have.  I discussed
this is with a long-lost friend recently, a real speaker buff; it turned
out he already HAD 105.2s.  However, he says they`re a bit large
(about a 17" X 17" footprint each) and said that in limited spaces
two KEF 103s plus a sub-woofer might be acceptable.  He mentioned
a powered sub-woofer from a company in L.A.; the name began with "A"
but he couldn`t remember it exactly.

So here`s a question on sub-woofers: 

Which one is the best?
Why are powered subwoofers made with amplifiers of as little as 30W?
I would have thought that much more (100W at least) would be desirable;
is the 30W a marketer`s decision?
How are they connected in relation to the regular speakers and the
amplifier?
How critical is room placement, and is this a function of the brand of
subwoofer?

Incidentally my friend has a Carver amplifier and a Sony CDP101 CD player,
which, like mine, has been trouble-free over the six months he`s had it.

Incidentally also, how much can be saved by ordering KEF 105 or 103
from England?
