My older system was the Bose acoustimass 5 which I never really got into. I can't really afford the sub for another month or two so my big question is can I still use the speakers without the sub? I heard on some forums the speakers were pretty good without one. I never really turned bass up anyways because I live in an apartment. I would appreciate the answer because I'm worried now that I won't be able to use the speakers when they get here.
