I need to get a subwoofer!!! I have a $200 gift card to Best Buy so my choices are limited. What do you guys recommend getting for under 200? Here is the site to check out to see what they sell. If anyone can help me that would be great. I was looking at the Sony SAWM500 for $199. My room I will be using it in is about 13x15. I have never owned a subwoofer so I'm not sure what I should be looking for. Also, if anyone knows of any good review sites besides audioreview.com, let me know. thanks.
