I am in the finishing stages of my dedicated home theater. Its a room that is 22'x12.5'. I put in a raised section for an elevated second row seating. Also put in three built in areas in the back of the theater to for a snack bar and shelves for stuff. Room is painted very dark, projector wall and ceiling is an almost black brown and the sides are a few shades lighter. Biggest challenge with this is the bulk head and lower ceiling height. In the process of purchasing all new speakers and projector and screen. I was hoping someone could give me their thoughts or comments on what I have selected so far. Any personal experiences with any of the equipment would be great. This is mainly movie watching and gaming. Budget for all listed below is around 6k and would like to stay in the ball park. I will also need a new audio rack as this is where my speaker will go.
Sony Projector VPLHW40ES
Sanus VMPR1 Mount
Monoprice 106" 1.0 gain Projector Screen
Polk Audio Rti A7
Polk Audio Csi A6
Polk Audio Fxi A4
Definitive Technology Supercube 6000
Looks like for the money you have made some good equipment choices.
I personally would have gone with a larger screen but in your space that would necessitate an acoustically transparent material so you could tuck your speakers in behind...and likely a wide "scope" screen aspect ratio to fit under the soffit.
Given all that, your 106" diagonal is a reasonable, low hassle choice.
You will need to hang some sound absorbing panels around the room to limit the bowling alley echoe, but all in all, looks like a great setup.
