I'm contemplating building some custom speakers and multimedia cabinets, and thinking about horns and bass.
(1) At the highest frequencies, if a horn/waveguide really holds directivity constant, then the response droops. Can Audyssey effectively EQ that back up, without needing another equalizer?
(2) The very interesting paper linked in the last post on the first page of

seems to indicate that, for instance, a smaller box with a higher Q is not inherently bad (it's the interaction with the room that equals boom, hey I'm a poet an' did'n know it 😛). This made me wonder, if you were building a sealed box tower or sub, could you then simply shrink it a LOT (from Q=0.5 to Q=1) and let Audyssey "fix it"?

You're right that what you get involves the room as well, however this doesn't always mean you can measure at your listening position and equalise what you see there just because it is a combination of the room and speaker.
Maybe in the bass you are more likely to get away with it so your idea seems worth a try, but the need to equalise bass tends to show that the response throughout the room varies due to modes. Room interactions are in various ways an acoustic issue that preferably call for an acoustic solution.

mmm, good point. I need to look more into how Audyssey EQ's the top end. Or possibly switch to Dirac. (I'd want to keep a receiver for multichannel, I don't want to be getting into miniDSP modules cascaded/stacked and all kinds of boxes and DACs. I won't have space for that).
Consider a conventional RC EQ for the horn. Audyssey can then tweak it.
FWIW I'm not a fan of Audyssey and switch it off with my horn two ways. YMMV

First off, I should have said this is a 5.1 setup maybe eventually 7.1 fed from either HDMI or from ARC HDMI. And this friend has zero interest in getting into like miniDSP boxes or whatever. Hence the question regarding whether Audyssey could do that function, though I should have said Dirac as well.
