Hell yea! I was just thinking about an isobaric push pull design the other day and was wondering why you don't see them much around here.

What are the pros/cons of these style enclosures?

isobaric mounting gives you double the moving mass, which lets you build a box half the size for the same output as a single sub. It also helps cancel out nonlinearities in the sub's motor structure for cleaner sound. Drawbacks? well, it takes twice the subs and twice the power for about the same output. I don't think there's any other way to fit 2 12s in a bandpass box in a trunk that size.

Sorry to thread jack Steve... I :wub: isobaric mouning

This is gonna be epic

Steve you never cease to amaze me. Your build get better and better. Cant wait to see how this turns out :drink40:

The spot with least resistance LOL.

I would ground to a rubber dildo if it had less resistance than a run of 4/0 wiring.

how many poeple work there 3 or 4 lol

At crescendo HQ? probably 2-3

At the sweatshop in china? 30,000 children

Pro is the Sound Quality is awesome. Con is it takes double the power to get the same volume level of a ported design.
