Im building a new box for my 2x xxx 15s since my last box blew up... im done fiberglassing the spare tire well and now im on to the box part... im wondering what would be the optimum port area, the box is 10 cubes after all displacements with the port i have designed now... 130 sq in @ 33hz, i was thinking i may be better off going with a bigger port say 200 sq in... any body have any insight on this?

200 might be a lil much and that would be one big *** port @33hz.lol

I'd suggest 180 sq. in. tops...

I'd shoot for ~150

i heard like 13-15 inch in sq ft for port area for every cubic ft of volume of the enclosure. 150 sounds perfect i would think.
