Driver for Isobarik use

Isobarik configuration doesn't really require specific parameters.
Just design the enclosure as you normally would for a given driver, except VAS will be greatly reduced. Two woofers in an isobarik clamshell config will only require half the space of one of those woofers. If you're planning on going the clamshell (face to face) route to obtain the reduction of distortion that's associated with it, or any time a driver's motor structure will be exposed, you should generally try to use drivers that are 'quiet' in operation, without excess mechanical noise from movement of the driver's parts, or from the movement of air through parts of the woofer, especially the vented pole piece (if it has one). Of course, I suppose the importance of this depends on the application. For instance, these mechanical noises are usually much less noticable in a mobile environment. Also make sure that neither of the woofer's surrounds will come in contact with each other when mounted. Also keep in mind that efficiency is greatly reduced, but power handling is greatly increased. It takes A LOT more power to drive a system like this. Mess around with WinISD Pro for a bit and model an Isobarik config to get a good idea of what to expect.
 
"You are right but then you lose most advantages of isobaric since air is loosely coupled and also power dissipation is greatly reduced."

Not only that, But also the added volume .

I highly suggest you find a sub or woofer that dont need too much box volume in the first place.
