ccrider540 Posted January 21, 2010 Report Posted January 21, 2010 i was wondering if the tuning frequency is affected if the port tube sticks out of the box. for example i was thinking about extending my port tube out of the box and into a factory subwoofer hole in my rear speaker deck. if anyone knows tis would be a big help. 1)Alpine CDA-117 1)hifonics brutus bxi 2610 1)hifonics zeus zxi6410 3)Alpine sps-600c 2)Fi BL d1 15s fully loaded
bkolfo4 Posted January 21, 2010 Report Posted January 21, 2010 It is fine. Just make sure when you calculate the port tube displacement you only calculate the portion still in the box. 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.
