The first one I tried after reading a barrage of good reviews in Amazon is Polk PSW 10, which to be very honest with you should not be called a sub woofer, because it all it does is some rumble sound and no base, next I tried the HSU STF-1, which I must say a fantastic product, had I have a bigger room and more powerful speaker set I would have settled for it, but my speakers were too small for it, so I finally ordered the Bic 1020, after researching that it has almost similar spec as with the STF-1, and boy what a choice, it is a perfect match for my system
