When I was at Cochella I ran CCM4's in front of the 722 and the bass was overpowering.. mainly the fault of the sound guys IMO.
I am back home now and running my ADK's again. Prior to the 722 I ran a V3 and nearly always ran a bass roll of at 75htz at 12db/octave... never had boom or muddy low end.
After Cochella I decided to do the bass roll off with the 722... changed it to 40htz and 18db/octave on the 722 and had a fantastic result.
FWIW I am not a fan of overpowering sub bass that has been digitally created at the booth... give me solid, tight low end that makes the music whole, not thump thump like a cheesy honda with a 15 in sub in it you can here for 3 blocks!
