Cabinet Type
The Paradigm Defiance X12 has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the Definitive ProSub 1000 have Passive Radiator type enclosure.
