bkolfo4 Posted May 4, 2010 Report Share Posted May 4, 2010 Yes, but when you calculate the port length, it is not a slot port, it is just a standard square port. 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.

lowrider77 Posted May 4, 2010 Author Report Share Posted May 4, 2010 ok cool thanks man, also is there any disadvantages to this type of design? Link to comment Share on other sites More sharing options...
Symmetry9898 Posted May 4, 2010 Report Share Posted May 4, 2010 not to thread jack but i had a question as well. Would the subs nearest to the port cause any type of turbulence issues or cancellation problems being that close to the port?

bkolfo4 Posted May 4, 2010 Report Share Posted May 4, 2010 I have built at least 2 like this. For daily/music, it will work fine. You can also just have the 2 subs on each side on the same baffle (no angle between the two subs on the same side).
