I cannot dispute that since I have not used, listened to or measured
those systems.  I did get a nice technical run-through of the JBL
system but not a demo.

Again.  No argument.  Filtering for room modes at low frequencies can
be quite effective especially since physical acoustical treatments for
those frequencies are bulky and generally eschewed by the domestic
user.  Simple electroniv magnitude EQ at higher frequencies can be
done but is more easily accomplished physically.

I have a similar experience with the Meridian system but several
Audyssey implementations have been very effective and more than
acceptable for domestic use.
