IKnowImLost224 Posted March 12, 2012 Report Posted March 12, 2012 I just made this box, it sounds like shit. I didnt know about port area before I made it. I wanna make close to the same thing except this time it will have a 3.75" port tuned to about 36 Hz. If I kept the sub firing up and just faced the port back would that be okay? Otherwise I wouldn't have much room for the sub to face forward. Quote
bobobass Posted March 13, 2012 Report Posted March 13, 2012 That port looks really small. I would stick with a minimum of 14 square inches of port area per cubic foot. Quote 2000 Subaru outback 2.5l Head Unit: Pioneer deh 4300ub front stage: tbd subwoofer: Stock Fi Q 18" amp: Audio que 1200d
IKnowImLost224 Posted March 13, 2012 Author Report Posted March 13, 2012 (edited) I know... I said that in the original post about the port being small and making it bigger Edited March 13, 2012 by IKnowImLost224 Quote
IKnowImLost224 Posted March 13, 2012 Author Report Posted March 13, 2012 Anybody??? Just wanna know if just facing the port back is gonna make that much difference Quote
Sheena Posted March 13, 2012 Report Posted March 13, 2012 well port back (at least in my trunk car application) results in a massive amount of trunk rattle which is rather annoying on a large scale. every application is different, so you'd have to try it for your situation.

Joe X Posted March 13, 2012 Report Posted March 13, 2012 Port back sub up on a trunk vehicle is a bad idea. Just doing a wider port neither is going to make a meaningful difference. Quote

IKnowImLost224 Posted March 13, 2012 Author Report Posted March 13, 2012 WEll I made it wider and kept it in the port area range on Torres until I got the tuning where I wanted. Should I try to do something with both firing back? Quote
Joe X Posted March 13, 2012 Report Posted March 13, 2012 Port back sub back can work, high port area (like >= 16 sq in per cube), tune 33-35, extremely solid build is necessary for this sub. Quote
