I'm moving into a new dedicated theater room shortly (yet to be constructed) & I'm wrestling with a speaker placement that is the closest to ideal for all of these formats, but it seems that I need to compromise one or the other. There's also the issue of back surround channels for DD-EX etc., I will have the capability but I'm not planning on using it as I'd rather save the money on those speakers to upgrade my current speakers. I feel that non-discrete channels are not where I want to spend my money at this time, and the fact that multi-channel audio is 5.1 also reinforces my opinion that 5.1 is best for me right now. (if someone wants to argue that I must-have 2 more matrixed rear channels, then go ahead...I'll listen ) So there's the issue of speaker placement for DD movies vs. SACD & DVD-A. According to The Dolby Guide to Home Theater Sound, one option is to place the surround speakers closer to ear level: http://www.dolby.com/ht/Guide.HomeTh...0110.html#s3.4 They also show the surrounds pointed toward the listening position, equidistant & on a "circle" with the front speakers. I was thinking that I could simply use a swivel mount on the wall for the surrounds to angle them in for DVD-A & SACD & point them straight at each other for DD. Is this really a compromise for DD? What about the recommended 30° angle for the front left & front right speakers with DVD-A & SACD? Is this a compromise for DD and/or 2-channel audio? Is the recommended 110° angle between the listening position & surrounds appropriate for DVD-A & SACD and DD? Is there a happy medium somewhere? I'd especially appreciate the opinions of someone who is currently using both SACD/DVD-A/DD in the same setup. (I do not currently have multi-channel audio & have not had the opportunity to experiment) If I have to compromise somewhere, I'd rather it be with DD than 2 channel audio or 5.1 audio. Any help is appreciated, as I want to run the wires in-wall to the closest location possible before the drywall is up. (not for a month or so yet) What if I do decide I want to add the back surround channels (DD-EX/DTS-ES etc.) to the back wall in the future? From what I've read, it's then preferable to move the side surrounds a bit forward, thereby messing up the position of DVD-A & SACD! It's a bit of a dilemma. For reference, the room will be 13 feet wide by 17 or 19 feet deep. The seating position will be in the center of the room, and this is intended as a 1-person theater, so I am not worried about catering the sweet spot to other seating positions. Thanks in advance for your help! -Dan B.
