I don't know much about Paradigm subs, the ps1000 seems to be
a very nice sub from what I've read. Assuming you have a 18 x12 room
with maybe 8' high ceilings, your looking at a little over 1700 cu ft.
A 15" titanic sub definately would be overkill for that size of room.
As for the 10" Sub, all I can say it's a pretty good deal, and goes down
to 30Hz. It's fast and musical. Driver is massive...link:

I have never owned a Paradigm speaker or sub. I've heard numerous
Paradigm speakers at Shelly's Audio in So Calif. and was very
impressed with there sound quality. Their top of the line sub is
extremely well regarded, but it's mighty expensive....you can try the
Parts Express 10" kit and see how you like it...but I think the Paridigm
sub would be just as good, and maybe hit a little lower (25 Hz verses
30 Hz).........good luck, vardo
