Subliminal Talk

I got new speakers. The logitech z323 and I tried listening to with and without bass and I noticed it makes a difference in sound distribution and noise. Shannon are we not supposed to use subs with bass?

So bring bass to 0? as for tremble im not sure there is a knob for that. I'm not understanding this lol

im using the same speakers

with the woofer knob turned on, the ultrasonics are not silent anymore... theres an irritating boom boom chika boom sound
