Interesting, and disappointing since I went back and forth several times over a few days to try to get a right answer. We went back and forth on the differences between the DSP settings and such, and he said he had checked with other engineers. Argh. Oh well, proof's in the measurements. I have never owned a QSC amp, and the only Crown XLS I have used are in our church sound system where a separate amp does sub frequencies. I don't have one around to measure. I was told that, while the XLS series had filters (both subsonic and ultrasonic), the XTi series does not. I do not know since I have not measured them.
I have used Crown amps in pro installs and for sound reinforcement work for decades but only rarely had one in my personal stereo (AV, now) system.
My apologies for doubting, but I had read all the same stuff, and thought I had gotten the right answer. - Don
