It's not a TSW60. I wouldn't be incredibly optimistic about this subwoofer, it's 50 watts and only $30, but for that price, it's not like you're blowing an incredible amount of money if something goes wrong. I can't find this sub online, it may be part of a component system that Aiwa stopped making and had an overrun of subs for or something like that... but regardless, I think I'm going to stop by tomorrow after work and get one. If anyone picks up one in between now and then, do us a favor and tell us how it sounds?
