Hey guys,

I need help on slot port length for my enclosure.
The specs to my enclosure are as follows: h 12.37", w 20.75", d 17.50" = 2.60cu ft. The port will be w 2.5" and one sid of the enclosure would make up the port ie. d 17.50". The height of the port is 12.37".

woofer: IDMAX 12D4V.3 displacement: 0.12

Amp :Rockford 1500db

I want to tune the enclosure at 27hz.

Thanking you in advance guys.
