What would you change if you were to rebuild your Home Theater?

[randman]

I'm moving to a new home and part of the basement is unfinished. I plan on putting a home theater in the unfinished part of the basement. Approximate dimension: depth can be up to 21' to 22', but width can only be up to 11'. 
One challenge is that the room right next to the home theater is HVAC equipment, which can be loud. So, I'll need some sort of soundproofing. 

Another challenge is that the room is not that wide. Maybe 11'. So, I'd be hard pressed to comfortably fit 4 home theater chairs  in a row. I'll probably go with 2 tiers, with 2 or 3 chairs for each tier. Ceiling height is only about 8' though.

Also, given the width, I'm thinking of getting an acoustically transparent screen so I can put the L/R speakers behind the screen instead of to the left/right of the screen. This will allow me to have a bigger screen. However, this adds additional expense so I can have a smallish room behind the screen to hold the speakers. Anyone have suggestions on how to do a build with an acoustically transparent screen (I imagine that occasionally, I'll need easy access behind the screen to adjust speakers).

I'm thinking of putting the equipment rack in the back of the room. Less distraction, and shorter cable to the projector. I'm thinking of putting it outside the room, since I don't use physical media anyway (I put all my movies on disc).

You put the speakers in the room. Then build a minimalist screen wall
So no separate room for you speakers. See pics

Thanks. What material is the black frame around the screen made of? 
Wondering what to do in case I needed to access the speakers sometime in the future after the screen was up.

I've never used an AT screen before. Movement of air from the speakers don't cause the screen to move, I assume? I suppose the movement of air comes mainly from subwoofers in heavy bass scenes, so as long as they're below the AT screen, then moving air wouldn't be an issue.

correct moving air isnt an issue  but COULD be if you dont leave a little breathing room from the speakers I would assume. 

the frames are made of 1x2 common board (some use FJP but is more expensive) wrapped in black velvet.  all panels are friction fit so easily removable to access all behind the screen.  

also note i stuffed all the cavity between the speakers with insulation to help with reflections and build a sort of baffle wall
