played a weird room last night, large, low ceiling, very live room wide verb with slapback, decent amount of windows part carpet part concrete flooring. i had us set up away from the walls as much as possible, we were put in a corner. i chained together a few cables together to get into the room about 55-60 feet to hear the mix. the vocals and drums sounded huge and awesome, bass was mushy. volume was amplified by the room and didnt help, we played as quiet as possible. i tried reduced bass then more mids on account if the reflections to get a decent bass sound but the size of the room wanted more bass to not sound thin with full band playing. ive dealt with reflective out door venues and other indoor venues similar gut nothing to this degree, any suggestion on combating this situation?
