Does anyone have experience with this type of driver configuration?
Is it true that you could half the size of an enclosure using this technique,
How important is the EPB of a given woofer in determining what type of enclosure it should be housed in?
Alot of manufacturers seem to state that there subs can be used in both sealed and ported enclosures, but to optimize the performance of your sub shouldn't you customize the enclosure to the parameters of your speaker?
Cheers, JMB

Here is how the IB loading is defined..
ISOBARIC: (isobarik, compound loading) - a method of using two drivers working in tandem in order to achieve a smaller box size for a given design. Theoretically, the Vas of the complete system will be half that of a single driver, which results in a net box size that's also reduced by half. The sensitivity of the isobaric system will be the same as that of a single driver, but you've got to spring for that extra driver! "Clamshell" mounting, where the two drivers are mounted face to face and one driver is wired out of phase, seems to the most popular isobaric system used today, as it is the easiest to build.

Here is a project , where u will see how the enclosure for 2 12" RF subs is made..

ok... thanx to Victor... i now have a general knowledge... but 2 add 2 what JMB asked... does an isobarik setup produce x2 bass? or bass equal to that of just one sub? ur still runnig power to 2, but displaceing the air of one... kinda confused... help me out...

2x the bass, no. it's jus a tricky lookin design.
