I am planning to add some speakers in my basement billard room. I only plann to use these speakers for music. (mostly POP music)I do not have room for a powered sub. So what speakers will put out great bass and sound good. I would prefer a larger woofer in each speaker 12" - 15". My main concern is having the bass without a powered sub. For a comparison I use Paradigm monitor 11's, in my home theater. These sound great but lack the bass out put I will be looking for. I also have a SVS 20-39pci sub and would like bass output simular to this. I know that I won't get nearly as much output as the svs but I would like a fair amount of bass. The room size is 26' X 18'.
