room size

Putting up a wall definitely will make for terrible acoustics.So many reflections bouncing back and forth.If you are determined,go ahead and prop up some plywood or even drywall across the opening and listen to your music.Then decide before you do actual construction if you can live with that long-term.

I have a question. In a concert hall, where are best seat in the house?

Very close to the maestro, or a GREAT sound man.

You see any walls behind them, or close to them... there is a reason.

Boundaries are not sounds best friend. There are lots of problems because of their use, and few problems, because of the lack of them.

Neighbors, maybe..

Regards

sounds like a plan thanks to all

Hi , the room is really 11x 32 ft ,laid out like this: stereo room 11 1/2 long then entranceway 5ft long then movie room 16 ft long for a total of 11 x 32 ft ,the whole front of my home, I have the speakers on 11 wide  wall 3 ft out & i sit about 7 ft from them ,after that the entrance ,front door then movie part with lots of furniture,I just thought if I put a wall with door behind me it might sound better, thanks for the comments, Lloyd

Why collect the boom when you can let into the other room?
Is there a privacy issue? Is the partner saying divide the room.
Do you think adding a wall is better? I'd ask someone to look.
If they said yes, close the room off. 
I'd keep looking, they're wrong to.

Treat the room, leave the wall open. Every wall will need treatment, no walls no treatment...Less walls less treatment..

Keeping one side wide open, what a dream... Ampa style..

I have a similar sized room. I keep my room door open and removed the closet sliding doors to stuff my desk inside of that. I also have GIK acoustic treatments.  Room sounds great now with small monitors.

When I get bigger speakers in this room I will likely also use Convolution files via ROON for my digital playback (not analog). This will help tame the low frequencies. I many not need to use it since I have the GIK acoustic treatmetns but the Convolution file approach is my safety net if things go pair shaped with bigger speakers.

I have some photos on my A'gon Virtual System of this room. Though I have rearranged a few things last week to improve the sound even more. I will add some photos when the new gear is in place.

Sure that can be your listening room, and you are off to a great start with the Prima Luna integrated. Can you sit with your back to the adjoining room? And what about that room, is it noisy? Dead? Lively? So much depends on details one can never know without actually being there. 

What we do know for sure, that room is almost square. Depending on the ceiling almost a cube. Not a problem now. Right now its not an 11x11 room its 22x20 or something like that. In terms of bass its all one room. Add in a wall though and now it really is a cube and one with the same bass modes side to side and front to back, that is to say really bad. 

That said, if you do build a wall it can incorporate some really cool bass control functionality as well as a degree of sound isolation. Just go into it understanding we are not talking about your typical 2x4 sheetrock and hollow core indoor door type situation. 

Do it right and you could have a thoroughly satisfying listening room. Acoustically dialed in and with enough subs it would be especially mind-blowing to close your eyes and feel you are in a huge concert hall. Which you could totally do.
