Regardless of what they say, wall mounting a dipolar speaker
is a bad idea. Conventional cabinets absorb the backwave.
Wall mounting these speakers would cause the backwave to
propagate right through the panel.

These are curved and are mounted on a metal open frame - so
the sound isn't too terribly messed up from backwaves. Also,
because it only goes down to 100hz or so, the backwaves are
minimal.

Sound Labs has a product called the Sallie ($970 pair)
http://www.soundlab-speakers.com/accessories.htm
which acts on the backwave propergation phenomena.

Why would the lack of low frequency output reduce the
backwave? Something thick enough to effectively
absorb the backwave kind of negates the advantages of
wall mounting. Sally is more of a dispersion device.

It seems like that to me. If the distance to the rear wall
is less than the length of the soundwave, simple acoustic
tiles or mat or simmilar will negate almost all of it.

It's the under 100hz that is still directional that is
the problem - and maybe a dispersion device like this would
work better, but yeah - a big thing stuck to the wall isn't
exactly the right idea. Just get a pair of Magnepans and
mount them on edge if you're willing to have a foot or more
intrusion into the room. The new MMG-W has a piano type hinge
exactly for this purpose. Fold flat when not in use, move
out to 90 degrees when in use. No backwave problems.

"effectively absorb "... please define this term?
Total (theoretical) absorption would have a negative
effect on a planar's sound stage performance. To
optimize performance is desirous to attenuate and
scatter the back wave.

By design it does this, too.

But are Magnepans truly "High End"?

Unlike your speakers they are, if one is talking about their top
models


Thanks for admitting that Magnepan is not a high end brand.


Except he's wrong. You're wrong, too.

As though anyone cares.
