I have a friend who has asked me to help him figure out how to set up a HT system the dream house he is now building, which is based on a Barn. Yes, a barn. He bought all the lumber from an old barn and is using it to build his house. The HT is going to go into his Great Room which is about 36' X 40' with the ceiling ranging from 14' to 27'. I calculate the volume at about 25,000 cubic feet. There are rafters crossing in 27' peak area that will be at about 17' (possible locations for side surround speakers). He wants to put the TV in one corner and have a main viewing area about 15' away, which is about a third of the distance to the opposite corner. So obviously he needs the biggest sceen size he can get, but cannot use front projection because of the large window areas which will not be coverable. So a 65" or 70" rear screen unit. He wants also to play music as well as DVD's & TV. He would like to use a 7.1 speaker set up. I am thinking a Denon 5803 for his receiver. So here are the questions I would like some help on: 1. Suggestions for brands/models of speakers. 2. The location of the L,C & R speakers is pretty easy, but the surrounds are not. He doesn't want speakers in or around the main viewing couch. I was thinking Rear speakers on the back walls and side surrounds on the rafters(which can be located fairly symetrically from the listing area). The side surrounds would then not be close to a wall or ceiling, but rather 17' up and to the side of the main viewing area. Should these be Dipole or Bipole speakers or should they be regular direct dispersion speakers? 3. Subwoofers - I assume two subs but I cannot yet convince him to have at least one of them close to the main listening couch. Any suggestions on which subs to use and/or some way of concealing one near the couch. The couch is going to be out by itself in the middle of the room, no walls close by. Thanks in advance for any ideas you would be willing to share.
