The primary reason I post this now is that I recently added the bass track to a collaboration we're doing. I thought some of the higher tones kind of disappeared in the mix, especially when monitoring without my SBX subwoofer, while my friend didn't really notice it on his HS50s.
The db levels of the bass tones were about the same, so I'm just trying to figure out if the BX5s have a "weakened" response for some bass freqs, if the HS50s are unbalanced the other way around, or if all this is because of my untreated room.
