    I'm having a new home built, and was wondering on where I could get info on the optimum size and shape for it....
    Is it true if the walls aren't parallel, that is good ?
    Equipment will be my current stuff...
    Mitsu 65 RPTV,
    N802 speakers, just 5 channels for now, but would go to 7 eventually.
    velodyne 15" sub
    Krell amps...
    Any suggestions are welcome
    Thanks
    Shelly

    If you want more than a couple rows of seats, then you need to consider perhaps a ceiling a little higher than the normal 8 foot height.
    It's not so much that you have to have a huge room (just not a bedroom size), but it's the dimensions of Height, Width, and Length (always rectangular shaped, never square) together that determine the best acoustical area for your a/v system.
    In the June 2001 issue of Stereophile Guide to Home Theater there are two articles on speaker placement and acoustics dealing with the dimensions of the room. There is also a free downloadable Microsoft Excel spreadsheet at www.guidetohometheater.com that works with these Home Architect articles. An interesting read.
    Also consider in your room's size the size of screen you want to wind up with in the future (especially if you move to front projection to augement your other TV, which is gaining in popularity). That will determine also how far back you must sit, how wide the rows can be, etc. Also the demands of the speakers you want to be using and how far apart and how far away from the walls they have to be in order to get correct imaging and soundwave placement. If you like a big picture and have the light output and resolution from the projector (and total light and color control in the room to make it pitch black) to do it, then 110" to 112" diagonal 16x9 (1.78:1) screens are very popular. You could even make one yourself- not as hard as you might think, so you have more money for a better projector down the road.
    If you ever do want a projector (be it CRT, LCD, D-ILA, or DLP), then placing a separate line in the ceiling (and having a lot of extra slack so you can place the projector at the right throw distance) is a great idea. Also, a long PVC conduit with a pull string inside going to your equipment rack and the approximate area of a projector (so video cable and remote control cabling can be run) would be a smart idea. Do it now, or it'll be a big headache later.
    Good thing this is a new construction job.
    There are also some great PDF Adobe Acrobat files to download from this site that helps to explain some of these things. There are always differing opinions on optimal performance and how to achieve it, but this can give you a start.

    Another thing is room isolation (top to bottom, side to side, and the door), and proper acoustic treatments after the dry wall is up. If you do not account for this during construction, even the best sound system in the world could sound like crud in the room. Another thing is possibly thinking ahead and having multiple, dedicated 20 amp circuits run to this room. Depending on future equipment needs and demands that could be maybe up to four or five circuits. One is for lighting only-- you do not want to have them on the same circuit as the rest of the equipment.
    HVAC considerations are another matter to deal with as well.
    Any other question, be sure to e-mail me if you'd like.

    Optimum room dimensions for a rectangle room are 1.00, 1.9, 1.4
    Second best is: 1.00, 1.9, 1.3
    3rd best is: 1.00, 1.5, 2.1
    These are inside dimensions for the room and will result in the least number of repeating room resonances.
