Default Push pull for VVX's?

I got two Skar 12" VVX subs, now I'm trying to get around to designing a box.

I have a Miller and Kreisel push pull home theater sub that goes HARD. After showing it off tonight I got to wondering how my Skar's would do in a similar setup for my jeep. Any thoughts? How should I go about the design?

Thanks!

You talking about an Isobaric?

are you sure your HT sub is an actual push pull? A lot that I have seen only have one actual sub and the other thing that looks like a sub is a passive radiator. sometimes they are too stingy to put two subs in lol.

"Push/Pull" isn't iso or a PR alignment. One sub is inverted and polarity reversed. A lot of HT's utilize this to stabilize the cabinet because the pushing a pulling forces from each sub are opposed.

It also cancels out some unwanted harmonics. Push/pull doesn't require any special modeling or design. Just design it like a standard dual sub enclosure and invert one with reversed polarity.

Haha yeah I'm sure. From what I can tell, my M&K sub is made by the people who came up with the idea. Mine is this product, but made back when it was M&K rather than just Kreisel

Thanks man, I appreciate your help. Does a push pull setup deliver and more/less volume/quality? (as opposed to ported)
