Hi all, I have got the Denon 3802 amp and currently only use 5.1 setup. I am moving soon and will be upgrading to a 7.1 (or 6.1?) system. I will tell you my system spec, then ask all you good folk some questions.(which hopefully you will be able to answer) I have a panny 42 plasma, which will be wall hung at the new house. I currently have Eltax Liberty floorstanders at the front, with Eltax centre and some Eltax Liberty 6 speakers as rears on stands. I hopefully will be upgrading to the B&W DM602.5 S3's for the fronts DM601 S3's for the rears and the LCR60 Centre speaker I have a yamaha YST 320 sub Some questions are: a) Do I use 1 or 2 extra speakers? The amp has outputs for two I think? b) Where abouts do I mount these extra speakers? The room layout is about 11 feet by 20 feet, with the plasma on one of the 11 feet walls, then I would have a sofa about 10 feet from the plasma with two rear speakers on stands about 4 feet behind the sofa on each side facing slightly in to the middle of the room. Behind the sofa is just 8-9 feet of dead space where we might put a small table etc. The main viewing place (the large sofa) is acroos the middle of the room, effectively blocking it (but we have another door from the kitchen into the 'dead space' area) c) Do I mount speakers next to the sofa on the walls on each side? d) Should I use dipole/bipole speakers for a diffuse sound? e) what speakers (di/bi) would match the B&W setup. f) which set of speakers would be the mormal rears in this case? g) or should I use another pair of say DM600 S3's for my extra pair of speakers? h) or should I use just one extra speaker? should that be another LCR60? or a DM600? or what? AAAAAAAARRRRRRRRGGGGGGGGHHHHH Basically, what speakers do you recommend for using a 6.1/7.1 system with the spec I have listed and where would you recommend placing them. Hope someone can help me?
