Audison APS 10 D Subwoofer Driver | 800 W Peak Power | 250 mm | 4 + 4 ohm

• Ultra-low profile (4.7 in. / 120 mm) for maximum installation flexibility. 
• Designed to deliver maximum performance in a sealed enclosure starting
  from 10 lt.
• Special designed cone-dustcap-basket geometry which guarantees a
  long linear excursion capability (11 mm, one-way) while keeping the
  mounting depth to minimum.
• Air vents on the basket underneath the spider, eliminating the need for
  the central pole vent allowing mounting close to rear wall of enclosure.
• Massive motor assembly, optimized with FEM (Finite Element Modeling)
  for perfect control under high power, high excursion conditions.
• Water-repellent pressed paper 10 in. cone, featuring a profile developed
  with FEM simulation and optimized with the Klippel Scan Vibrometer.
• Dual voice coil design specifically developed to be combined with either
  AP8.9 bit (2 CH + 2 CH bridged), AP5.9 bit (Sub CH) or AP4.9 bit/AP4 D
  (2 CH bridged) amplifiers.
• Steel mesh grille and plastic gasket included.
