why do most of the subs I have heard make loud droning sounds on music but on movies? I like lot of elecronic based music and some acoustic. well a lot more acoustic and rock music lately I am going through a girl rocker/ country/Acoustic Phase along with the dance music. The only standalone Sub that didn't Drone badly is the Used Audio source sub that they have at My local pawn shop that's been there for several years still on sale. I better go get it before someone beats me to it!
