Whatta Ya Think About Hsu Research Subwoofers?

IMHO the best subs they make are the  VTF-15H MK2.

You really need two, located properly in the room, but they mate better than any other model I was able to audition.

Yep Bob, the 10" woofer is down-firing, the cylindrical enclosure sitting on tall spikes which raise it off the floor. A Parasound amp will be fine with them, and as I said the subs came with a passive x/o, so no extra electronics are required. The two woofers can be replaced, or even just re-coned, which I was thinking of doing. I don't know what the price to have that done would be.

Hello bdp24,

     It seems like you're not aware that Bob is using his stereo Parasound A21 amp to power his ML 60XT main speakers.  He can't use this same amp to drive a pair of passive subs, he'd need another separate amp to power a pair of passive subs.  Or, he could use a pair of traditional self-amplified subs.

@noble100, So Bob thinks he can run his speakers and a pair of passive subs off the same amp at the same time?! You’re right, I wasn’t aware he was already using the Parasound on his loudspeakers. I was assuming he knew what a passive sub is ;-) .

I know what passive loudspeakers are, but I wasn’t sure if the Parasound could power both the ML towers and subwoofers.  From reading responses, I now know the answer is No, I would need a separate amp to power passive subs. I’m thinking I will go with new powered Hsu subwoofers, the ULS 15’s, which I can get in gloss piano black for $779 + $80 shipping each.  So $1718 for two (plus tax that will likely be added).  This is comparable to the SVS SP2000 Pro subs in gloss piano black that cost $1699.00 for the pair with shipping free.  The SVS have 12” drivers while the Hsu have 15” drivers, which sounds like more bang for the buck with Hsu.  The Hsu subs that wspohn recommended are somewhat more expensive and are ported designs, which are said to be better for home theater (not my interest) but less desirable for music (bingo!). Just thinking out loud here and I am always open to other opinions.  I thank bdp24 for his ideas as well.  I try not to agonize over every decision, but also try to avoid buyer’s regret.
