InfiniteRuckus Posted May 30, 2010 Report Share Posted May 30, 2010 I was just curious what size ports are on the edge of too small (to the point where port noise is a serious factor) for both round & slot ports. i tried to search this topic but mainly came up with port tuning instead of port noise.

treossi Posted May 30, 2010 Report Share Posted May 30, 2010 I was just curious what size ports are on the edge of too small (to the point where port noise is a serious factor) for both round & slot ports. i tried to search this topic but mainly came up with port tuning instead of port noise. from like 13-20 inches per cube of port area was always pretty good to me.. i ran 30 inches of port per cube for a while.. just under those numbers causes some breathing problems Quote Team sundownWESTCOASTSPL.COM we're throwing dbdrag events very soon visit the website for details Link to comment Share on other sites More sharing options...
InfiniteRuckus Posted May 30, 2010 Author Report Share Posted May 30, 2010 how wide was the port? Quote Link to comment Share on other sites More sharing options...
bkolfo4 Posted May 30, 2010 Report Share Posted May 30, 2010 The required port area will depend on the sub, the volume of air it can sweep (Vd), how much power you will use, and tuning frequency. Using anything else to size the port is an estimate or guess. . . You can use smaller ports if they are flared.

AssKicker Posted May 30, 2010 Report Share Posted May 30, 2010 I do about 16 per cube, 1.5 cubes of space, works phenomenal so far. Gets loud and hammers the lows. Quote Link to comment Share on other sites More sharing options...
loburbon Posted May 30, 2010 Report Share Posted May 30, 2010 dont forget also just because you have the right port area doesn't mean you wont have port noise. an example is a 10x10 port for 100sqin should have zero port noise. but if you make a long ass 50x2 slot port your gonna have a shit load of port noise.
