You don't see many people taking this view, so I have no idea where other sources might be found.

From a book that I'm familiar with:

Tip #13: Should you accept the “non-parallel walls are best” theory
for your listening room?

OK, there is a case to be made for non-parallel walls in listening rooms.

But it’s fraught with peril.

I tend to think of this as one of those myths that got started and just
won’t die. I’ve been involved with the design of custom listening
rooms where the walls weren’t parallel, including some that I designed for
myself. With the exception of one, all were problematic at best.

Some so-called experts suggest building one or more walls at an angle
(non-parallel) on the horizontal plane. For example, the opposite walls
may be 15 feet apart at one end of the room and perhaps 16–20 feet apart
at the other end.

I’ve been able to “play” with different geometries and found that the
only thing that is consistent is that you cannot consistently predict what
that room will sound like!

It’s almost impossible to determine how such a room will perform. Bass
standing waves will have no easily predictable pattern. Contrary to some
claims, there’s an excellent chance that you may never find a place that
permits smooth bass along the length of a single sofa!

Another issue that arises is found in corners that become more acute
angles than the normal 90-degree corners you find with conventional construction.

For the most part, these corners tend to collect more bass and
to generate more mid/high frequency slap echo.

The single instance where non-parallel walls worked was when we introduced
a subtle effect on two walls where the walls very slightly leaned
inward. This caused the mid/high frequency reflections to be reduced.

Best regards,

Jim Smith
