I'm not missing any upper bass/midrange with the Ultra blended to the M22. I set up the Ultra in 15Hs mode with room correction off. I did have to use the single stage equalization on the Ultra to tame bass centered around 60Hz and get a flatter overall response. I had to use correction tables for the SPL meter to adjust out it's response. I have the M22s crossed at 80 Hz so I'm not stressing them and the Ultra has plenty of output left after the equalization is applied.

Whose avatar should I borrow next?
