Home Theater Building

4.43.186.77

Posted by Brian LaCroix on July 16, 2001 at 23:53:21

We're in the process of building a new home, and I'm setting up the home theater in the gameroom above the garage. The room is going to be 18'W x 27'L x 8'H (although I think I'm going to ask the builder if the ceilings can be bumped up to 9'). Luckily, the wife gets into the home theater even more than I do. First, here's a list of equipment I currently have:

Processor: Denon AVR3300 (I've been thinking of moving this to the living room and replacing it with the Sunfire processor)
Amplifier: Sunfire Cinema Grand Signature
Fronts: Magnepan 3.6
Rears: Magnepan 1.5
Center: Magnepan MGCC
Sub: Velodyne HGS-18
Screen: None yet
Projector: None yet

We were discussing painting the ceiling and possibly the front wall black. How dark do the side and rear walls need to be, or can we go with a medium color? I was thinking a medium blue or something. I've also heard people talk about sound-deadening paint. Any info that can be offered would be helpful.

We were looking at a Dalite screen that is 92" wide. From what I've read, the screen width should be approximately 2 times the distance to the first row of seating. We were planning on putting the first row of seats at 14-16', so this should work if this is good advice.

My biggest question is about center channel and subwoofer placement. I'm concerned about the MGCC not being powerful enough, and that I may have to get another one to back it up. If this is the case, so be it. My bigger concern at this point is placement. If we are to raise the second row of seating 5" and the second row 10", would above the screen or below the screen be better placement? Also, would placing the sub in the corner or center of the room give the room more evenly distributed bass (not particularly volume, as I'm aware that corner placement is best for this)?

We're having a closet converted into an in-wall equipment rack, and I figured once its all in, I'd make a nice oak panel with cutouts for each item in the rack for that professional look. I even had a dedicated 20-amp circuit pulled into the rack, and a dedicated 20-amp circuit installed in the front for the subwoofer.

Any other suggestions would be greatly appreciated.
