[net.audio] sub-woofers

sasaki@harvard.ARPA (01/03/85)

While searching for speakers I have come across several that have excellant
(at least to my tin ears) imaging and higher frequency sound. The problem
is with the bass. As a specific, the Spica TC-50 sounds very good to me
(and the price is good!), but it seems a bit bass shy. Reviews of the
speakers have all mentioned that having a sub-woofer would fill in the
bass.

What is involved with a sub-woofer? Do I need another amp? How do you
separate the signal that goes to the sub-woofer from the rest of the
signal? Can I really get by with one sub-woofer or do I need two? If I
need another amp, does it need to be of high quality and output? There
are several sub-woofer kits, are they any good?

The dealer wanted very badly to sell me a sub-woofer that costed an arm
and a leg.
