i am a bit of a bass head plus my velodyne CHT-10R has to keep up with my CV VE12's, so i run the mains at 0db, center at 0db, surrounds at +3db and sub to +6db with the volume set at midway exactly, and dsp set to jazz (no bass boost) sometimes i set it to movie mode (boosts lower output). hey i love the bass!!! plus the VE-12's are very clear, and the onkyo amp i have is not able to really push the 12 inch drivers, although it does a decent job!!
