this set up doesnt make sense to me i've never seen subs face to face, it doesnt seem like it would get much bass out of it-------------

that would not work well. it looks to me that 2 subs will be totally sealed. i woyld think those voice coils would get way to hot.

Woofers "face to face" is called isobaric loading. ISO loading creates a system with 1/2 the required Vb of one woofer. The configuration shown would create a high-output SPL system. No, the VCs would not get too hot. It's no different than standard sealed mounting.

isobaric, also known as a "push-pull" system is great for being very controlled. All you have to do is wire them out of phase. They will take alot of power and keep the make up stable.

Man, that takes me back. I remember building that exact enclosure for 4-10" Petra Prowlers back in the day.

great info on this subject and would like to add something to help stripes26051 understand it a little better. when this is set up for push and pull one woofer pushes and one pulles just as described but when you through the woofers out of phase (wiring them) to create the push and pull effect . in this app. you need to make sure the other set of woofers are in the same operation as the oposing ones. or they will cancel each other out.

each column repersents a woofer.

One of the hardest hitting systems i have heard with 10s.had four blaupunk 10s set up like that in a porsche way back when isobaric enclosures first came on the scene. But it has to be built perfect or it sound like junk.
