hey guys, I'm putting together some scrap pieces of audio equipment to make a sound system for the playstation 2 and I just need an adequate subwoofer. I'm using the philips AV receiver that's shown here and sound old weatherproof altec lansing "model 52" speakers. These speakers aren't on the altec lansing website cuz they're so old (instuctions booklet says "copyright 1995"), but the specs they list are: 4" cone woofer, 1.5" Dome Tweeter, 48Hz-22kHz plus/minus 3 dB (highly doubtful), crossover at 3.5kHz, and 8ohm nominal impedance. Anyways, I'm only putting this setup together cuz I have that stuff lying around so I don't wanna spend much money at all on the sub. I saw a $30 8" Jensen sub at BrandsMart that of course is looked down upon here, but is it the best deal for the price? Can you guys find a better sub for, say, $50? Also, if I put this kind of setup together, what kind of performance can I expect? For sure, I know it would be better than the tv speakers, but what about compared to $100 computer speakers or the bose accoustimass? If I can't beat those then maybe I should even try putting this thing together.
