Ive just got done with a new build and ive got a little hearing damage now i guess so it doesnt seem loud enough after a few days. I wanna try and do a ported setup now, and just build a new box. The manufacturer reccomends 3.25 per sub tuned to 42 hz with 3x 4"x12.5" round ports, or a slot port with 37"^ and 12.5" long. Ive got 2 of these right now in a sealed box, and they get decently loud but i wanna get it louder while also learning how to do ported boxes. What would you guys do with my setup?
