: I haven't bothered to look at the rear woofer configuration in my M, but if they are really push-pull (sealed chamber between them) they are in what is called an "isobaric" configuration.

This is how it appeared in the pictures I've seen. I have not taken mine apart to look at it.

: The advantage to an Isobaric configuration is not that it "simulates" or is "equivalent" to a larger driver, but that it allows the use of an enclosure of 1/2 the size required by a normal single speaker configuration.

Yes, that is ONE of it's advantages. Another is increased power handling. Another is greater output than from just one speaker.

It reduces the efective value of a speaker parameter called "Vas" by 1/2.

Correct, as usual, my good man, LOL.
