Mart,You really don't end up with a true air seal, the rear cabinet is placed up against the planar speaker frame and the foam sealing strips just help prevent vibrations and the worst of the leakage, they do not provide an air tight situation.
Such a box size is rather large, and even if there was an actual air seal to this rear chamber, the amount of air 'compression' would be very slight, and the rock wool/Miraflex would tend to absorb some of the backwave energy.
I have heard this on an electrostat, and on a Maggie, and both instances were quite amazing how much it cleaned up the sound field (going from a di-pole to a mono-pole radiator was a large part of this) and how much the bass was extended and made more solid.
The easiest way to address planar bass extension is to use the bass traps, they get about half of the improvement that the huge box does, with out all the hassle and space.
