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.
