rocking.that.eclipse Posted February 17, 2016 Report Posted February 17, 2016 So I found this nice little approximation for resonance of a single sub in a sealed box. It is: Fs* SQRT[(Vas/Vb)+1) So i'm wondering how do you take this single approximation and modify it to fit for more subs. I know that resonance will change as you add subs and you increase sealed side as long as you don't make each sub in its own box (ie sealed box with 6 12s all common chamber will have lower resonance than 6 seperate sealed boxes for said 12's) Any help or insight would be awesome

lutkeveld Posted February 17, 2016 Report Posted February 17, 2016 AFAIK box resonance frequency doesn't change when using 'n' subs in a box that is 'n' times as large as a single box. My WinISD sims confirm this.

My WinISD sims confirm this. So youre saying that a 1 cube box with 1 sub in it will have the same as a 6 cube box with 6 in it

ALPINE408 Posted February 19, 2016 Report Posted February 19, 2016 in for this record breaking system on paper! dont get to caught up in calculations with vehicle variables the only true way to get loud is test test test and test some more Have you ever had your woofers blown?
