bkolfo4 Posted April 23, 2013 Report Share Posted April 23, 2013 Have you already built the box? If not, can it be any larger? As the port gets longer, the net volume gets smaller, which makes the port have to be even longer. . .going to lose a lot of net volume to get to 32 Hz. 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.

Ryan_H Posted April 23, 2013 Report Share Posted April 23, 2013 If his setup would allow it, adding external port length would save from loosing net volume. Link to comment Share on other sites More sharing options...

Joe X Posted April 23, 2013 Report Share Posted April 23, 2013 It's changed in the linked thread, however can't figure out how do you know 35Hz is bad if you didn't ever build it. Or how do you know 32Hz is good for that matter. Link to comment Share on other sites More sharing options...
