RE: Agree to disagree.

No. That's not the reason.

Theoretically, a perfect dipole does not excite modes that are orthogonal to the dipole's alignment. Practically, these modes will be excited at greatly reduced levels since the radiation pattern won't be perfectly symmetric and the dipole won't necessarily be perfectly aligned with the walls.

These effects are real and can be measured at low levels, for example by equalizing the dipoles to that they have flat on-axis response at the frequencies involved. If this is done with "wimpy" speakers the resulting low bass may be inaudible due to poor bass hearing at low volumes, but the room modes will still be there, nulls and peaks.
