heh kinda long title but that about summed up my question. I'm looking to build subwoofer to complement my newly aquired Vifa XG18 / Seas 27TDFC MTMs. and was wondering- what's good? My bet right now is the dayton kit on partsexpress. But I wouldn't mind building my own box. Just as long as all the parts are under $500. I do watch a lot of movies but wouldn't wanna trade the sub's music quality for that 'boom' factor. so, could you guys recommand me a sub under $500 that's for music? thanks.
