Anyone heard these? I'm wondering if they are OK to check out. They are
a coaxial horn loaded tweeter design with built in DSP to compensate for
room nodes.

They've sounded pretty good for speakers in demo rooms which is the only
place I've seen
them. John Gatski reviewed a set for Pro Audio Review (I don't think
it's been published yet)
and he thought they were pretty good. Kind of expensive, though.

DSP doesn't really compensate for room nodes, but it can help somewhat.
Mostly what it
does is first correct the speaker system so that what hits the room is
accurate. Then you can
bugger it up as much as you want.

They're a square box with DSP to compensate for the box modes and for the
horn resonances.

They don't sound terrible, but listening to them makes it very clear that
there is a lot of processing going on. They sound as "processed" as the
Meyer HD-1 does. I count that as a big black mark, but on the other hand
they give you the narrow dispersion of a horn system and the "processed"
sound sure beats the "horn nastiness" sound of the traditional horn
alternatives.

Trying to compensate for room nodes is like failing an IQ test - it is a
fool's mission. Nodes are a great place to dump near-infinite amounts of
power, get no useful SPL improvement, and possibly cause problems elsewhere
in the room.

The horn drivers appear to be diffraction-based constant directivity horns.
Constant-directivity is good, but the sharp break at the end of the throat
is a big give-away. I'm under the impression that diffraction-based CD
horns have been eclipsed by newer designs for at least 20 years. Of course,
some of that newer technology is patented. I'm under the impression that one
of the potential licensees might be footloose and ready to deal.

One reason why diffraction-based CD horns were obsoleted, is because of the
series of nulls that the sharp change in horn impedance causes. AFAIK, it
takes the about same amount of plastic and molding to do it right.
