Enclosure questions!

[Buffalohed 0]

I'm in the final planning for the enclosure I am having built inside the trunk of my Camry for 2 15" Mags. I haven't decided exactly what to do with the ports though so I need some advice.

First off, I have 9.3 cubes gross to work with. The base model I am working with is 29hz tuning with 93"port area, 34" length and 7 cubes net for the Mags. But playing around with WinISD I have found a couple other things that work as well. For example, 29hz with 93" port but 7.4 cubes and only 32" port. Or, 30hz with 101" area and 34" length with 7 cubes net.

My goal is powerful low-end and of course SQ. I might compete casually with this but I would really like to get good numbers at like 30-34hz. What would you recommend towards this end? More port area and slightly higher tuning with 3.5/sub volume, or less port area with a bigger enclosure and lower tuning? I know nothing about how ported boxes work so any advice would be fantastic.

Also just real quick, can someone tell me the displacement of the 15" mag?

Thanks guys.

The displacement of the 15" Mag is 0.15 cubes each. And I highly recommend sticking to what we recommend on our web page.
