It has been a steep learning curve so far. The flat frequency response into the room in the treble freqencies does not sound right. Looking at the in-room frequency graphs of the more highly regarded speakers measured by Stereophile, all show a decreasing response in the top end, usually ending up around -5 to -10 db at 10000 hz. The thing to remember, when adjusting the filters is that you are manipulating the measured room response and not the speaker response.
My basic setting for P1 after 6 days of trial and error has resulted in using the "shelving high" filter set at 4000 hz with the level set at -3.0 db and a Q of .6. The other filter I used was the "low pass" filter set to 12500 hz with a Q of .5. I left the bass and midrange frequencies set to flat. So far this has resulted in the most natural balance. With this setting, I have a -7 db point at 10000 hz for an in-room setting.
The supplied manual isn't very helpful with instructions at "how to" achieve an acceptable in-room response. Perhaps some other users can relate their experience as well.
