My Bose LifeStyles system is on it's last leg and needs to be replaced. Originally, I thought to simply replace the receiver and use my BOSE speakers with a new receiver. However, after reading forums on this site, I see that isn't necessarily in my best interest, and I may have made a poor purchasing decision years ago.
The room is 41ft x 15 ft with the TV along the 15 foot wall (projecting into the 41 foot space). I have the couch set up at 12 feet away from the TV with the surround speakers 3 feet behind the couch (hanging about a foot from the ceiling). I was intreagued by the reviews of the Blackstone TL1600 and Pioneer SP-PK21BS, but not sure if these are good sets for my space. Any recommendations would be appreciated, and I'm hoping to use my current dimensions/set up if possible.
I should also note that I did wire two additional wires for 7.1. Although, I lost my map that would enable me to easily find the ends again, I know they are about 6 feet from the TV on each wall (about halfway between the TV and couch). Is it worth cutting out some drywall to find these and upgrade to a 7 speaker system?
