Posted January 3, 201213 yr and lower tuning.. plus the subs heat up the enclosure, bad for the amps too, so better cooling!Port is 24" long now for a 22Hz tuning, I get bad cancellation I think, so I will do a 30" port which will reult in 20Hz
January 3, 201213 yr Maybe i'm wrong but i don't think changing tuning will help with your cancellation problems, from looking at your pics of the inside of the box i would be inclined to think you have way too much interference going on inside.

When I ripped out the old port completely, leaving the 10" thick wall as a 10" port...that should have raised tuning to 27Hz and been hella louder...but it was dead... even more cancellation. I'm making the port longer to keep the rear wave from cancelling through the short port. Though I should lose dB from lowering tuning, I think it will be similar or increase from stopping the cancellation.
January 3, 201213 yr Author From rear wall to bottom of invert mounted sub is 52", subtract 20" for 1 port diameter end clearance and 2" for play 30" port

January 6, 201213 yr Author So on the right is the new 30" port for a 20Hz tuning. 20" off the rear wall for 1 port diamerter clearance and will stick out the front of the wall as far as the inverted subs will... but see, the one on the left, 43", keeps staring at me. It would come out the wall quite a wayze and right inbetween the front seats... 2 free ends....18Hz tune... ah shit, here we go!
