Sub recommendations for HT


What are some good subwoofers in the $500 - $800 price range for a large room. I'd like to keep the sub itself as small as possible though. I have considered the Sunfire subs but they are a little out of my price range.

Thanks for any help.

I thought the Sunfire junior sub will fit your price range, and possible a used Sunfire also -- I might be wrong. ACI Titan used to offer a kit package that costs about $700-800. Both Sunfire and Titan II are good with bass for music and movie. I recommend doing some hunting and get a decent sub, then you will not regret. Have fun!
Definitive Technology Subwoofers make great HT subs, and you can find them for pretty cheap.

I used to have the Definitive Technology Prosub 200, 12in driver 250rms, brand new it cost 549.00, never had any problems with it and it was a damn fine performer. Personally i liked it better than the equally priced velodynes. Worked pretty good for music, but excelled in HT.

Unfortunatly i had to sell it. WHen i rebuilt my HT thats where im going for my bass. But i will probablty splurge for a SUPERCUBE
