Jeff, I think that's what I've been saying, "Just that it isn't a panacea for every issue." and had said previously. RC can smooth out the room response but won't handle reverb, first reflections arriving just late enough to smear the sound and all the other nasties that take proper room design and treatment.
RC does make a nice first step for those for which treatment isn't possible. And it does some things much easier than moving walls to correct standing waves. At least partially.
Of course ideal room can be more than a challenge. Not all of us can go out and have a bespoke room done. Love to do it but I'd have to use an iPod and dock for the next 10 years or so to pay for it. Assuming I stay employed in this administration.
And I'm starting to be sorry I started this fuss even though I still believe Theta is going to have to add EQ or RC to compete properly.
