Wassup guys I'm doing a port swap in the next few days and trying to get opinions/suggestions. I have a box 39.5h x 41.5w x 13.5" d (outer dimensions) with a port 12h x 10w x 40" l which gives me 6.8 cubes tuned at 31hz with 17.75 port per cube. It's just not giving me as much pressure I want on lows. The new port is 12" o.d. Pvc (11.5" I.d.) x 36" l with 2-4" external. This will give me about 8 cubes tuned at 29 with 14.25 p.p.c. I don't have anything to lose, and I'm not building a new box until I design a 6th. So what are your thoughts on what I have now?
