Ok this is just a question that I think the answer is pretty obvious but I may be wrong.  What is the perfect shape of an audio listening room?  Is a room that is not symmetrical a big problem.  I have a room that is the shape of a rectangle its 24x14x10 but there is a little 4x3 area for an entrance and the ceiling angles down on one end from about the last foot to about 9ft.  So it isn't a bad room but not perfect. Most rooms I imagine aren't perfect.  My wife and I are starting to look at some houses and an audio video room is on the want list but I want to make sure I know what I am looking for.

A good audio room is the Golden Ratio (no room treatment need.).
But the Cardas Golden Trapagon is better.

I had an 8ft x 13ft x 21ft room, just a smaller version of above (limited by ceiling height).  It was all insulated drywall, except for the carpet over concrete floor.  The interior partitions were staggered stud construction even though the spaces on the other side were storage rooms.  Used a fiberglass insulated exterior door with weather seal and flexible lined/insulated ductwork (could barely hear the furnace fan).  Builder refused to provide a suspended ceiling construction so I could hear footsteps above.  It was in the basement (no windows) and opposite all living areas upstairs.  So nearly perfect.

I added GIK 244 panels but they were barely needed.  I lent them out to a restaurant that had a serious noise problem and they ended up buying (23) 242 panels.  I took them over to a friend's place and they made an immediate improvement.  I used the Cardas formula for speaker/listening position setup (mid-field).  It was ideal.  Unfortunately we've moved the the room in the new house is too small for a mid-field setup (even for monitors), so I've reverted back to using headphones which for my failing hearing is OK.

How much money, time and effort do you want to spend?

I remember an article many years ago that started with a “Golden Ratio” for a dedicated listening room, then made sure that the walls were non- parallel, increasing width and height from the front to the back. Special Materials. Double-studded walls. Lots of details.

But, definitely- Golden Ratio.

A good audio room is the Golden Ratio

Golden Ratio is only special because it has irrational ratios, many nrooms with different irrational ratios work.

But the biggest bdifferencemismmade with a sloped ceiling.
