Ported Box Volume help for 2 rockford rosgate p3's Help

[RyanV]

What should the volume be for this box?

Also what should the port size be to tune to 35 hz ( I think this is the ideal).. can do either a circle tube port or a slot port.

I have most of the dimensions mapped out, i just need to adjust the width of the box according to the volume.

I put my P3's in about 3.6 cubes net, tuned somewhere around 33hz. They sounded OK. Port was 3.5" x 13" - about 24" long.

There are various calculators you can use to find the dimensions you're looking for:

Rockford Fosgate® - Woofer BoxWizard

RE AUDIO - Box Calculator

Car Audio - PORT Size Calculations and Formulas for WOOFER and Subwoofer BOXES

I think most would suggest something like torres if you're running windows os.

What diameter/length I could use for a circle port? seems easier for this box shape
