Great idea.

So I talked the wife into letting me angle the ceiling the question is how much of a slope should I incorporate?

The more the better but I think 6 degrees is minimum. Trevor likely knows more.

All the tilted in ceiling models you can buy are either 15 or 30 degrees.

I think the only 30s I have found are the Golden Ears. Rest are 15.

Trevor, Canes wants to know how much tilt he ought to incorporate in the ceiling to minimize standing waves.

None. Standing waves are not defeated, just moved. Splayed walls are only good in rooms where ceilings taper too. Always shrinking with the direction of sound away from the source.

Build a rectangular room and treat the ceiling with decending polycylindrical diffusers. Room should shrink as it heads further back in height. Using suspended polys allows tweaking after the fact and backing the panels with roxul to create membrane absorption. Will upload pic later.

Doing this will eliminate ring and flutter.

Is it necessary to cover the whole room in this regard or can I take it just beyond the main listening area, theater space?

I think it’s dependent on the room. Once you have one, a room that is, then you can figure out if you have a problem and how to solve it.. Otherwise you might find yourself solving something non existent or even creating a problem. I’m definitely guilty of predicting all kinds of audio room problems, spending lots of what if time, coming up with solutions, and never having to implement them since ... it was not a problem in the first place.

The room is defined by boundaries and Canes is trying to establish the properties of those boundaries. You have a blank canvas, Canes. Maybe you ought to do some research or hire someone for a consult.
