Get your phone and tell it to play a 300hz tone. 250-300hz is the highest bass notes.
I run Bass (including MB) columns, separate from the mains and subs. 60-300hz. I think you're mixing up percussion with MB it can go pretty high 500hz and higher maybe 800 or so.. Play a 800hz test tone.
Few system please my bass taste. I can't stand a rattling sound system. The whole house vibrating..
60-80hz down is GRs OB servo system.
60-300 bass columns
300-25khz Small planar/ribbon hybrid LS
Calipso, ska, reggae, and merengue music my system just really makes it fun to listen to without going bass deaf. The way servo pressures a room, makes a lot of difference on all the rest of the frequencies.
