Is there any advantage to having another midbass driver positioned directly behind the external midbass driver inside the cabinet with the 2 magnets facing each other and the internal driver is wired with reverse polarity to the external driver in an isobaric configuration of a bass reflex cabinet?
Isobarik halves the Vas, so, ignoring the coupling chamber, the box volume can be halved. Magnet-to-magnet will dance the magnetic field to a large extent, but the chamber being (iote. abit deeper, the extension at the top decreases (already decreased in any isobarik) so it makes little sense.

Thank you for your reply. Would the coupling chamber in such a magnet to magnet config be a sealed compartment within the bass reflex cabinet or would the 2 midbass drivers use the total volume of the bass reflex cabinet? I am just trying to understand this configuration as design concept.
A small sealed environment. One driver would see the inside of the box, one would see the outside world, but both will feel each.
In this arrangement, the 2 mid bass each at 8 ohms wired in parallel would be treated as 1 speaker at 4 ohms? Would the cross over be designed as if designing for 1 woofer at 4 ohm in a 2 way (tweeter / woofer) setup?
