I have a Harman Kardon avr 3550 and a yahama subwoofer yst -fsw050. Its a 7.1 system. Just curious what the best setting would be in general. I have turned on the LFE on my sub setting. and adjusted the db to 8 db. and also turned the bass management up to 7 . Is this too high? I would like some cinematic background thud while watching tv or blue ray movies, i jsut dont want to blow anything out. Anybody have any ideas?
