IH8PunkRok Posted January 30, 2011 Report Share Posted January 30, 2011 ive looked over a lot of places and the definition ive found is "the amount of air equivalent to the 'springyness' of the subwoofer's suspension" now how does this factor into box design? should the box volume be close to the vas? or is it useless info? -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
bkolfo4 Posted January 30, 2011 Report Share Posted January 30, 2011 Your description is correct. It describes the suspension stiffness vs. compression of an equivalent volume of air. Check this out along with the frequency response tab: http://www.diysubwoofers.org/prt/ported1.htm 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.
