"Isobaric dipole"...
Christ... :P
Enclosure was built to Adire specs... 1.25 cu.ft. each, 3" diameter x 14" long port to tune it to 30hz.
Except this enclosure was built for two Brahma 10's, not one... and even though it was still reasonably compact in dimension, it was thoroughly braced, including a large pair of center braces that had cutouts to cradle the hulking magnets.
I took a couple construction shots... but forgot to take pictures of the completed box, so I'm glad that HB did.
