Help Building an Audio Room

Hi All

I have been allotted a 15x15 x 10h room in the corner of my basement by the wife.
While I’m very happy to have a dedicated audio room, I have some questions and concerns. I’m hoping you all might be able to help. 

1) Three of the walls are poured concrete.  The space has crazy slap eco already and the 4th/back wall is not even closed in yet.

I am having the walls framed in, insulated, electrical, drywall etc. I am thinking of having them frame and build one wall an additional distance off the cement wall some amount so the room is not a square

Is that a good idea?  If so, how much out of square does it need to be to benefit from not being 15x15? Is 15x14 enough? Should I go for 15x13?  I can set up the speakers about any way I would like. 
 

2) Next question.  Should I have them install a certain type of insulation behind the drywall?  Money is an object, but now is my chance to build the room the best way I can within reason and to offset the square room I’m starting with. 
 

3) Anything else I should consider before/as they begin to frame, etc? 
 

Thanks very much!

That's probably overkill but maybe you can find a few ideas to incorporate in your new space.

I highly advise not having a square room because of the room nodes you will build into the room automatically by those dimensions.

Do some reading if you have the time on acoustics with room nodes.

15x12 is better than square. Maybe you can go 15x20? The more you can stay away from square the better off you'll be - at least acoustically. You'll still need some bass traps - especially with poured concrete walls.
