Deaf Bonce Fight R12 Sub Unbox / Box Design

Machette MF-12R D4, got it on a Down4Sound B stock sale. This thing is a great sub, with very rounded performance musically and reaching low into the 28-30hz range without batting an eye at it. Powered by a Skar RP1500.1 @ 2ohm, 2.2 ft^3 box, 30 in^2 port, 25.75 in long port, tuned to 32hz.
