fecupe2001 Posted October 10, 2012 Report Share Posted October 10, 2012 Depends on many factors, box size isn´t even that important, what sub??? 24SQ of port should be enough for a daily application, my current 12" box has 42SQ of port I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

DAD KMH 12, honda prelude. I do have a 4" psp aeroport. Been trying to come up with a box for it. Torres says it needs to be 11.5" long but im not sure how to factor in the flares Link to comment Share on other sites More sharing options...

bkolfo4 Posted October 11, 2012 Report Share Posted October 11, 2012 Add an inch to the port for end correction. Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

SCS_Audio Posted October 11, 2012 Report Share Posted October 11, 2012 Add an inch to the port for end correction. Correct. Torres adds in end correction but it seems like the tuning is always lower than calculated. It auto calculates one flanged and one free which should be correct when using an aeroport. For example, if you have a 6 inch tube in between 2 flares, your port length would be 12" (if each flare is 3"). I would type 13" into torres as your length and the tuning will probably be closer to that than if you type in the real 12" physical. Box size, box position, and other things affect how close the tuning will be as well. 2012 North American Street Stock Runner-up - 150.9 on 1800 clamped watts (Teammate)2013 dB Drag Street Trunk World Champion - 153.9 on 3200 clamped Watts (Teammate)2013 MECA Trunk 1 World Champion - 152.8 Headrest (Teammate)2013 MECA Park & Pound 2 World Champion - 130.6 (Teammate)Checkout our build and videos !! : ) 150+ Trunk Build Log itsgordy1 youtube channel (click for Hairtricks)Smith's Custom SeatsMartinsburg, PA (Second Skin Dealer) Link to comment Share on other sites More sharing options...
