I'm selling my Paradigm Studio 100's, Studio CC and PS1000 sub to help pay for a new amp i'm going to buy for my 2-channel system and when I redo my home theater I thought about getting power towers like the Def Tech BP2006TL with a Def Tech C/L/R 2002 center for a smaller but still nice home theater. Does anybody here use power towers without a separate sub and do they produce enough bass for home theater without needing a separate sub?
