Given the extremely narrow perspective into the realm of speaker
design and manufacturing that, to be frank, makes amateurs
amateurs, this is not surprising in the least. At least one
reason behind this is amateurs are not constrained by nor,
generally have ANY idea whatsoever on what it means and the
constraints imposed with having to build to a price point as one
primary design goal. An amateur worker can sit ther and fiddle
with veneering a cabinet, spending hours or days getting it
"just right" and end up with a result that, if it had to go to
market, would end up selling for an order of magnitude more than
what it is commercially worth.

There is an exception to the DIYer vs commmercial firm equation,
though - that is, if the speaker doens't have a box to tweak
or design(planar/stat/stat/etc)

I suspect that it would not be that hard to duplicate a Magnepan
if you had access to the same panels.
