hi, i found this one subwoofer at radioshack.com and the price is quite low. the specs looks quite good based on the info on this page
http://www.adelcom.net/BIC-VSeriesSubwoofer.htm. the model number of the sub is BIC D1210R. the price at radioshack.com is $159. i planned on using it for a home theater, but i'm not sure if it will provide good bass quality. the size of my home theater is 15'x20'. can anybody who knows about subwoofer or have used this specific model before tell me if this sub would be good enough for a room of the size i've mentioned above. also, i would highly appreciated if anybody knows a good sub (10"-12") for home theater at the price of $350 below. thank-you.
