If, as you contend, the subs are omni and they cannot be aimed then take your
pro sound subs and turn them around being careful that they stay on the same
plane. Do you think you will notice a difference in FOH? What about onstage?

For a single 12 inches non-horn loaded playing below 80 Hz, I'll bet it
would not change a thing. Actually, if there is some wall behind the
speaker, you may notice an increased output.

However, a stack of 18 inches playing to, say, 120 Hz would be quite
different because the mutual coupling of multiple drivers would cause
some directivity in the higher bass.

Meyer went to great lenght to design a "cardioid" sub and the thing have
4 drivers, weight 400 lbs, need extensive on-board processing and huge
power to run. It's certainly not commonplace yet.

If you know of a single 12, 15 or 18 inches pro sub that have some
directivity below 80 Hz, please post references.
