Today I tried the auto eq, and in the beginning it didnt like my levels...so I kept lowering them until I had 80db. I then went through the process of the EQ, and ended up with this result from my MLP. With my old tune I was going past 10k before it started dropping. Auto tune def gave me more 20hz though, by about 10db! Now one thing I did is I ran REW the first time with all my presets blanked on the Xilica xp4080 and i never set and crossover. So I am assuming REW just EQd it to be +-5db, but as you can see it did not do enough to get me to 20khz. Should i raise the gain on the horn and rerun it to get it to extend more on the top end? I will hopefully have my new F20 subs in the next week or two and was planning on rerunning REW anyway. Ultimately I would like to have it 20hz-20khz as flat as possible to a curve with a gentle down slope from 20HZ to 20khz.
