Use an acoustically transparent fabric to cover the rear of the driver (as used on old Klangfilms etc.).
Fill rear chamber volume with chopped up pieces of foam (see above post) or whatever you want as long as its in small pieces. You could even use cork; maybe even wine corks, available from places that sell wine making kits.
Vary the quantity of solids to adjust the volume of air.
I like this solution much better.
