Default Acoustic lining.

Some years ago I read about a lining material for speaker cabinets (possibly in Coice Coil magazine) which claimed to increase the effective internal volume of the enclosure. I am going by memory but I think it was a solid porous material - possibly graphite based. Has anyone heard of this matertial or others like it?

KEF developed a material based on activated charcoal which was claimed to effectively increase the cabinet volume by adsorbing air under pressure and releasing it when rarified IIRC.
