What is your budget? I am sure many folks here would suggest some other items that will perform better than Bose for your money.
Bose home theatre
With the passive subwoofers on the entry level Bose systems am I going to get the bass out of it I want without an amp? Also, if I go to the digital 5.1 and the right/left speaker outputs on teh sub don't specify front and back, will I get the true digital surround? I know these are basic questions, but I would really appreciate some help.
