I think I'm in the right forum, but if I'm not, please accept my apologies. I recently decided that I wasn't spending enough money restoring old cars so I decided to edge myself a little closer to complete financial ruin by building a proper home theater (as opposed to the 32 inch TV with bose acoustimass 10 system I was using). I bought myself an LCD projector, 100 inch screen, and Denon receiver to enhance my experience...but here is my question for the people who actually know something about this. I have a large (16 x 20 foot) room dedicated to this theater and decided to save a little cash by using my old acoustimass 10 system. For those unfamiliar, this is the bose system with five double cube speakers and bass module. I am now very disappointed that my sound just is not as big as my image so I've been trying to figure out a way to make more moise and stretch any dollars I have left. My original plan centered on the purchase of a mid-priced Sub and center channel speaker and then eliminating the bass module from my bose system and connecting the remaining cube speakers directly to the receiver. I would also be purchasing an economically priced speaker to use a center surround speaker so I could make a 6.1 system out of my 5.1 (my receiver can handle 7.1). Now I'm starting to wonder if my money would not be better spent buying a very good sub and keepng the Bose Bass module to handle the lower frequencies between what the cubes and the sub can handle. I would stiil be purchasing a CS speaker...but this might allow me to buy something alittle better. What do you all think about my plan? Thanks in advance for your help.
