I just got an enclosure and was wondering if anyone might help me with the specs on it.
I was wondering what the freq. and size are.(Just thought I would have someone tell me what they get for the size I can figure that out myself)

The box is 14" Tall x 32 1/2" Long x 11 1/2" wide. I got like 3.2xxxxxxx for the size but I don't know how or if you need to compensate for the port, I have never worked with circle ports I usually stick to ported.

It has one circle port on it that is 7" long x 3 1/2" Wide.

I appreciate any help thanks.

well im not the best at backtracking like this but my math shows that if ur external dimensions are 14" Tall x 32 1/2" Long x 11 1/2" wide and ur using 3/4 inch mdf then ur actually 2.24ish cubic feet internal..slightly smaller after u subtract ur port.. and the tuning is around 34hz..correct me if im wrong lol..just thot id give it a shot

thats all i ever use

you can enter the wood width and find the internal volume then subtract speaker and port displacement

i also use the windows calc

how do I find the port tuning? and port displacement?

14" Tall x 32 1/2" Long x 11 1/2" wide. 3/4" MDF

It has one circle port on it that is 7" long x 3 1/2" Wide.

And from what I found the sub is .24 displacement
