Here are the frequency response captures of the four systems we listened to at the KC g2g as taken from the sweet spot.
Yes, my room is heavily treated with zero slap echo. Not quite dead, but close. My foam(which is said not to work according to the guys that sell treatments) was completely dead! The wall treatments are not quite dead and look better. Besides the treatments my walls are all 100% fabric covering sound board which kills high frequencies. I wanted this because I want to hear the speakers direct sound and not echos. Even with all that there are still some issues. My response is +/- 2.5 dBs from 80hz to 20khz and yours is +/- 7 dBs. Big difference.
You guys can clearly see why you commented on what you did.
JTR's- best midbass(they had a 3dB advantage)
eD's and JTR's best dialog on movies, again they had an advantage with a higher peak up there. The DR's had the lowest vocal range but the highest 2K-10K range, that would probably make them brighter, by a lot.
Your two favorite speakers had the most rolloff from 3K and up which tells me in Carps room my JBL 4675C's would have wiped the floor with all because that is their natural response! Of course for HT only. Music they were OK. To me the response shows everything I need to know and again, your two favorite speakers had the same response minus the midbass which I can bet the JTR's had the most. The JTR's also had the smoothest response.
