I was really... really lucky when we bought our house... I accidentally chose a house with a near perfect listening area. My high audio guy says he has never heard one as good... and he has decades of experience installing many $200K systems. So, let me tell you what I think are some of the features which helped it.
.
First it is a daylight basement. The room is not a room but an area within a large area of an open plan and the system is set up against a wall that behind it is underground and is a solid concrete... dead silent. Also twenty five feet or so, left or right it is also underground... Dead silent. The downstairs is a sprawling Z shape with the audio system in the center of the Z. Isolation is created by it being down stairs and the living area is upstairs. The center audio area is 25’ by 35". Behind me is my library... open passage 15’ wide...then goes off another 15’ feet away from the audio room. To my left in the center is a hallway away to a couple other rooms. The space is rife with bump outs (bar... closet under stair)... only the wall with the speakers is straight. The ceiling is 8’ or whatever is standard. Above my seated head is a lowering of the ceiling by a foot... perhaps for the air conditioning... it is finished. I am not saying this to help you duplicate it. But that the key is quiet and asymmetry in all places except the fromt wall.
.
Also, my partner is disabled and has real sleeping problems. The bedroom is upstairs and on the other end of the house, so I can turn my system to any volume and it does not ever wake her.
.
Carpeted floor. I think the behind me being open and a long way to the back outside wall is an asset as no reflection.
Put dedicated lines on all three walls near your expected system location. You are sure to decide to move it at some point. It is really cheap to do now. If you are sure... put two outlets. Make sure the electrician wires them on adjacent breakers... putting them in adjacent breaker boxes can cause a ground loop between the outlets.
.
If this site has PM. I’ll be happy to send you some photos, them may make it easier to understand.
.
If I was building a room, and didn’t know better... I would have built a "room".. but a sprawling area is much better!
