Hotdog Posted May 31, 2012 Report Posted May 31, 2012 you should be able to build a 3:1 ratio 4th order in that area. around 8ft3 sealed and 28ft3 ported Quote (NEW) 2004 F-150 Build Log -->http://www.stevemeadedesigns.com/board/topic/192208-hotdogs-f-150-build-log/ 2003 Mercury Mountaineer Build Log --> http://www.stevemeadedesigns.com/board/topic/114380-hotdogs-2003-mountaineer-build-log-20-removed/page__gopid__1602379#entry1602379 2008 Equinox Build Log --> http://www.stevemead...g/#entry1475764
Stee-Z Posted May 31, 2012 Author Report Posted May 31, 2012 ok. so from my max measurements what would be a good box height width and depth if i'm running four 15" DC XL's on a DC 7.5k ? I'm not quit understanding the ratio portions of this fully. so basically make your own whatever you want box design, find the resonating frequinecy then tune it where the peak of that frequency is correct?

Hotdog Posted May 31, 2012 Report Posted May 31, 2012 (edited) yea and the ratio thing is not hard to grasp. if you want a 3:1 ratio then your ported chamber needs to be 3x the volume of your sealed chamber. and you want to find the sealed chambers resonant peak frequency. you tune at the peak frequency Edited May 31, 2012 by Hotdog Quote (NEW) 2004 F-150 Build Log -->http://www.stevemeadedesigns.com/board/topic/192208-hotdogs-f-150-build-log/ 2003 Mercury Mountaineer Build Log --> http://www.stevemeadedesigns.com/board/topic/114380-hotdogs-2003-mountaineer-build-log-20-removed/page__gopid__1602379#entry1602379 2008 Equinox Build Log --> http://www.stevemead...g/#entry1475764

Stee-Z Posted June 1, 2012 Author Report Posted June 1, 2012 O.k. so from my understanding this is what the insides should look like, two sealed enclosures, then you find the resonant frequency of the ebclosure and where the peak of that is at is where my port should be tuned to. Correct me if im wrong Quote (4)DD 9918's (2)DC 10k 8 6.5" focals 2 DD SS4 mid amps Audison Bit One processor Jl-cl-rlc line driver iPad in dash Dual Irragi 320a alts 8 batcaps 4000's Second Skin sound deadened
