DatDude619 Posted September 17, 2014 Report Posted September 17, 2014 Doing a 4th order bandpass Like this but 2 woofers Gonna be 45w 20h 30 deep Going 1.75 sealed each with 8cu Ported total. Tuned to 45hz (magnets on Ported side) (slot ported) How much port area do I need to get the right compression with these subs in this application
SQL50 Posted September 17, 2014 Report Posted September 17, 2014 I'll reply since nobody else hasn't.. I'm not really familiar with bandpass but I have a p3d4-15 in a slot.. rockford recommended 40 sq in of port for the recommended airspace which was on point with about 15 sq in of port area per sq ft of useable airspace.. so I would think that this 12-16 sq in of port area would apply to bandpass also.. someone enlighten me if im wrong.
CleanSierra Posted September 17, 2014 Report Posted September 17, 2014 The same logic does not apply. I'd do 150-180". Half the cone area is 176". Last bandpass I did was for a single P2 10" and I gave it 36" which was half its cone area. It was a great all around box and did a good job on 150W. Im not the one you want to try to troll. Just a fyi for you.
