Not really, only that a studio dumped it there. Or, FAR more likely....a studio hand had a mate into subs, so the hand bought or stole the sub from the studio, he then flogged it to his mate who took it home. On getting it home said mates WIFE said (or shouted) DWAYNE!!! You aint never not no way brunging that thang inta here while mah kiddies is needing food and slippers! Dwayne dutifully thought 'what the Tom Hanks is ah gonna do with this puppy'. The rest, as they say, is history.
Flipping nice model though eh? I just love these big things.
