I play with a drummer that has a difficult time hearing my bass unless he has a loud monitor or iem. My question is this: since the bass rig is generally next to him pointed forward (of course) and asuming that we are not set up with a monitor for him, will a rear ported speaker help him to hear the bass better? He happens to be a hard hitting and hard of hearing but very good drummer. I have considered a two channel bass rig just to be able to give him his own bass feed. All of my cabs happen to be front ported. Just wondering if rear ported cabs would help him hear the bass?
