I'm daydreaming about a room with the same shape as the typical Axiom cabinet...I want one.
Even if you had to build a room inside an existing room...

Lol
1 drink, I swear.
But seriously if a guys was to build a room why not use the shape?
Even if you did build it into an existing space the space behind the wall coverings you would see would make an exellent space for bass traps.

Its interesting that in their example the room is widest at the rear of the room.
Pretty sure this example is for 2 channel audio.
I was thinking the widest part of the room would be at the front to allow a wider L&R spacing. I'd like to get 12'-14' apart and have around 4' from the side walls.
The depth of the room would allow the sweetspot to be at least 12'-14' away and have a full row of seating behind it.
Wish I still had a PC. Guess I'll dig out the old graph paper and waste an afternoon.

Seriously, the fan shape has been one of the classic designs for theaters and concert halls for a long time, although it has been falling out of favour recently because the lack of parallel-ish sidewalls and associated "immediate echo" is felt to reduce the listening experience.

The interesting question though is whether that applies to a listening room, since one could argue that the purpose of an audio system plus listening room is to recreate the sound of the original performance including the acoustics of the hall in which it was performed. One can also argue that since we tend to have to put wall treatments at first reflection points maybe those first reflections are not wanted anyways.

There may also be a moderate degree of angling (similar to what Axiom uses in its speakers), smaller than a typical concert hall, which maintains enough in the way of side reflections to make the room seem "alive" but still reduces the standing waves at low frequencies. Only thing is that AFAIK the walls would have to be pretty solid in order to have an effect on standing waves, and that would probably be incompatible with putting bass trapping behind them.

Anyways, a listening room with angled side walls has always been on my list of things to try when time permits.
