Piggi3 Posted March 6, 2013 Author Report Share Posted March 6, 2013 Here are some pics. I took my port out so now it tuned to about 49hz. 31x11x2.5 in 21cubes. Quote Link to comment Share on other sites More sharing options...
Piggi3 Posted March 6, 2013 Author Report Share Posted March 6, 2013 It's not sealed up yet properly but I think it should be louder then what it is. Quote Link to comment Share on other sites More sharing options...
corona_jeff Posted March 7, 2013 Report Share Posted March 7, 2013 Based on your sealed side at 4cu per chamber. I'm gonna say you need to be tuned in the 47-49hz range. But of your tuned at 49 with our port out, I'd leave it there and play with it. Once th subs FULLY break in, slowing shrink port. Again I see you best results around 46-49hz tuning. I would shoot for a port size of 360-390 sq Based off mine, which still needs a few tweaks. It's 7 cu sealed and 22.75 ported, tuned to 50.5. And that tuning was figured for brand new subs put the sub. I need to slightly lower tuning now. Quote Link to comment Share on other sites More sharing options...
Piggi3 Posted March 7, 2013 Author Report Share Posted March 7, 2013 Ok. Thanks Jeff. I'm at 341 right now 31x11. All try 31x13 and see what happens that will be 400 " of port. Quote Link to comment Share on other sites More sharing options...
