Looks like a home brew attempt at magnetic shielding to the rear of the speaker. Either that, or someone just wanted it to weigh a bit more. ;-). I'm not sure how much sound would actually make it through the holes in the "Grille" material.... certainly nothing low frequency. Maybe it was not for sound, but some kind of acoustic resonator.

With any luck, the builder of this contraption is an ARF member and will remember it ............ 8)
