I have a room that is 20ft long and 15 ft wide with 9ft ceilings. The end wall is flat with no windows. I would like a HT with projector and use the wall for a screen. I plan on tiering the floor for seating, using a butt shaker along with a sub. My thought is to have a front ground level, seven feet back step up seven inches, then seven feet again step up seven more inches.
Questions:
Should I divide the room in thirds for the stadium/tier seating?
I have a five thousand dollar budget for equipment right now, how much more will I have to add to be happy?
I want a 7.1 system.
I will carpet the floor, what about the walls, any sound cloth needed?
Any suggestions are greatly needed for my system, I am not a guy that uses this as a hobby, but I want a great room to watch movies in.
