I am looking to build a box for a dd 2515 15" woofer, I have read the specs on their site but I am not possitive on how the port works, how do I know how wide to make the port and where the port turns in. Anyhelp will be greatly appreciated or a push in the right direction.

Thanks again

Kerri

 

my 9515 I had in a box that peaked @40hz I now use my comp box daily which is 46hz though.
393.6mm high
863.5mmwide
504mm deep
port was- 355.6mm high
76.2mmwide
504mm long... I should made the port a little longer, but peak @ 40hz was good for me.
This is based on 3/4" MDF
