Box is 10.42 before displacement, minus subs and vent I have 8.9 cubes. They call for 1.5 per so that's close. For the vent I have 96sq in" at 24x4 and 12.25 deep tuned at 35hz does everything look okay guys? Green light?

Autruche Posted April 17, 2011 Report Posted April 17, 2011 That doesn't come out to 16 inches per cube, it comes out to 10.8 per cube. Definitely needs more port, imo. I got it at 8.65 cubes, and that makes it about 11 square inches per cube. Just doesn't seem like enough port to me. Box volume seems good though, and you were right with your tuning. If those are your max dimensions, maybe try aero ports. Quote Need Test Tones/Sine Waves?

mazdaspl Posted April 17, 2011 Report Posted April 17, 2011 I think that its going to be alittle on the small side.. I have accounted for sub displacement and to me it drops it down to the mid 7cuft.. Jay Quote
trafficjamz Posted April 17, 2011 Author Report Posted April 17, 2011 So I'm going to need about 130sq in of port?

trafficjamz Posted April 17, 2011 Author Report Posted April 17, 2011 (edited) Can someone help with the vent? Pretty please I can do up to 37" wide by 4" tall port which is way to much but that's my max also the box is 18" deep to more than likely I'll have to bend to port....
