The subs blend well. I use the highpass filter built in the E112s and have them passed at 60hz. To use the highpass I can put of the “preamp” into the subs then out to the amp.
I measured the frequency response of the room then did minor gain tweaking to taste by ear after that. I get flat bass plus or minus 7db. I have a 7db spike at 30hz and a 7db hole at 55hz.
