I just got a design from supergumby and it turned out perfect. 2.5ish cubes tuned to 32/33hz. Port was 3" by 12"Alright have the money for a new box, just need an offical design so i can see how it is and if it fits well. Im thinking something around 3 cubes after box and port displacement at around 35Hz?
Ive seen some boxs on youtube for 9512s that have huge looking ports.
