How much bracing? Cause that will have to be subtracted from the overall internal area which will change the tuning blah blah and so on and so forth

15mm is about .6" that isin't too bad you shouldn't have to brace it that much

Well lets say for arguments sake not more then .05cuft of bracing, so could anyone please tell me if my estimate for the port length is right to tune the box to 35Hz?

Cheers, for your help

INTERNAL DEMINSIONS:

15.8 H x 19.8 W x 14.8 D = 2.679416 NET - .07 (bracing) = 2.6

PORT FACE = 12" x 2"


PORT LENGTH = 15.26" (not including port or sub displacement)



so that 18" length should be fine... take care
