I am moving from 5.1 to a 7.1 system and I need some advise on the placement of the new 2 channels. My 5.1 system sounds fine as it is so I can't and don't need to change any existing speakers. Right now I am using a 15 year old sony 5.1 receiver and it looks like I will be getting the Denon 2112ci soon. My speakers are infinity alpha 50s and matching center and infinity primus for the surrounds.
Here's are my options; (Red color on pic is existing speakers)
I originally wanted to add rear surrounds but they will be very close (see green option on pic). Behind the couch is a window and they will literally have to sit on the lip of the window to work. Many people said that it is too close and would be a distraction and would be better off with front wides or highs.
I have no room for any more tower or bookshelf speakers so they will have to be in wall or in ceiling. I just got some in walls really cheap that I never even heard of. They are a pair of Dayton Audio 85 watts 2 ways. They look brand new and just holding them in the air , I was very impressed with the sound.
I know they would not be timbre matched to the infinitys so I would think that it may mess up the front wide immersion effect but I have a very small place to use them in wall as front wides ( see blue color option on pic) they would be a pain in the butt to instal in wall but could be done.
Finally, I could do in ceiling which since highs would be more ambient sounds, it may sound better being that they are not matched to the infinitys. (see pink puke purple color option on pic)
I have plenty of freedom to move the in ceilings where ever they should go but the in wall front wide option can only go in the spots on the pic due to openings, bricks and stuff.
So what should I do to get the best out of what I have to work with? I have a feeling from my research that in ceiling would be the best and if you all agree, where should the in ceilings go? Directly above the front mains? Can I widen them out? Right above the listening area? HELP PLEASE!!!
