I need help designing a ported box for my pro 5100, it will be used as a ht sub.
My room is 18 long by 15 deep with 9 foot ceilings.
I have it in a large ported box that is tuned to 36hz I believe and I am pretty happy,
But I would like to check into how to get a ported box tuned much lower in the 20s to maybe teens.
can anyone ponit me in the right direction?
i dont have any software.
i like pr's but i don't want to spend the money on them.
