Hey guys,
I am in the process of building my first box and I think I'm gonna need a little help.
I'd like to build a ported double-baffle box like Steve did a while back but I'm having a little trouble figuring out how to get it tuned right.
Link to Steve's build.
My question is: Which calculator would you use to tune the port? I can't find one for this style of box.
I'm gonna post some pics of my build so far but I'm warning you...this is a fuckin trainwreck.
Looks like a goddamn coffin. LOL
For future reference:
Subwoofers: (2) 12" Rockford Fosgate Punch HX2
Details:
* dual 4-ohm voice coils
* CONsealer gasket hides mounting screws and prevents air leaks around the frame
* frequency response 26-200 Hz
* power range 150-500 watts RMS (250 watts per voice coil)
* peak power 1,000 watts
* sensitivity 88 dB SPL
* top mount depth 5-13/16"
* sealed box volume 0.8-4.0 cubic feet
* ported box volume 1.75-4.0 cubic feet
Recommended Ported Box Volume: The ported box volume range recommended by Rockford Fosgate is 1.75 cu/ft to 4.0 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 2.0 cu/ft, so this is the enclosure recommended by Crutchfield. One 4" diameter x 10-3/4" long port, tuned at 35Hz, should be used with a 2.0 cu/ft enclosure.
