Alright, I've need designed a ported box befor and I need someone to help and or design one for me. I'll pay to have it done if needed.

Anyways the sub is a 12" Fi Q. Box specs for what I have to work with are H-18" | W-36" | D-9", with using 3/4" MDF that works out to 2.471ft^3. I have no idea on what port area size should be used, if it needs bracing, etc. I would like it tuned to 33Hz.

Thanks :)

Ok... I think I got it, I just need to know should I go with 2" or 2.25" for the port width?
