I recently bought a pair of subwoofers (on the used market)
made by Spica to match the TC-50's.  Unfortunatley, they are out of
production.  They cost me $400 each.  I felt that
was a small price to pay for stereo subwoofing.  If I
had gone with Velodyne, for instance, I couldn't have
afforded the luxury of two subwoofers.

They are servo-controlled with 50 watt amps made by
the respectable PS Audio.  One 8 inch Audax driver (DVC maybe??)
in a 1.25 cubic foot sealed box.  They supposedly go down
to 25 Hz.

My comments are that they seem to integrate with the TC-50's well,
although perhaps not as well as I'd like.  They do not get that
ultimate deep bass that shakes walls.  The cross-over is
at about 70 Hz, and they seem to free up the TC-50's so that
they can concentrate on the stuff above 70 Hz.  On the negative,
the subwoofers take up alot of space, 
and I can't turn them on unless the downstairs neighbors are
away.  The TC-50's still sound great alone.
