isobaric resonator? - Click HERE for Original Thread

I think isobaric means to abutt to drivers cone to cone and haveing them move together? what if you moved the drivers apart with an air volume. this air volume would couple with the drivers at its resonance and damp everywhere else? I think of it as holding a fishtank full of water and sloshing it around. has this design ever been studied?
thanks

An air gap/chamber between the two drivers can add to the effective mass property of the cone. You'll have to search for your own references, I wouldn't imagine it's that easy to pull off in practice compared to what theory predicts.

It's not only been studied, it's been done commercially many times. See, for example, the Dynaudio DA500 from the '70s and the more recent Consequence.

cool! what keywords should i search when i do some research?
thanks a bunch.

The Decware Housewrecker does exactly that in a 6th order bandpass alignment. The isobarik chamber in the middle smooths the response verses a typical 6th order bandpass.

facinating!

isobaric, -3dB sensitivity,half box requirement. Good for lots of cheap woofers.
