Dr. Toole has said that EQ can help for room effects, but it can't fix a poorly designed speaker. Frequency response is important, but you can't just look at on-axis. A smooth and predictable off-axis response that mirrors on on-axis response (though with a more downward slope as you move further off axis due to directivity of the tweeters) is just as important as a smooth on-axis response, and EQ often doesn't fix problems in off-axis response.
So, proper EQ can help make a good speaker sound even better in a room, it can't fix a speaker with fundamental design flaws.
As far as the various levels of Revel speakers go, while all are designed to exhibit the best on and off-axis response as possible at their various price points, there are benefits moving up the line.
Moving from Concerta2 to Performa3 (and now Performa3 Be) to Ultima2 you get greater bass extension, greater power handling, greater dynamic range capability, less dynamic compression, less distortion at extreme dynamic levels, etc (plus of course the intangibles like more nicely finished cabinets and such).
Playing material without much bass content at a lower volume the Concerta2 F35 should sound remarkably like the Ultima2 Salon2. Change the material to something with deep bass content and a very wide dynamic range played at reference levels and the differences will become apparent.
The new drivers in the Performa3 Be offer more dynamic headroom, lower distortion at extreme volume levels, and stronger motor structure/better cooling to decrease dynamic compression.
