Audison APS 8 R Subwoofer Driver | 500 W Peak Power | 200 mm | 4 ohm

• Ultra-low profile (3.11 in. / 79 mm) for maximum installation flexibility.
• Designed to deliver maximum performance in a reflex enclosure
  starting from 8.5 lt.
• Special designed cone-dustcap-basket geometry which
  guarantees a long linear excursion capability (almost 9 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 excursion conditions.
• Water-repellent pressed paper 8 in. cone featuring a profile developed
  with FEM simulation and optimized with the Klippel Scan Vibrometer.
• Specifically developed to be combined with either the Audison AP8.9 bit
  (2 CH bridged) or AP4.9 bit /AP4 D (2 CH bridged) amplifiers.
• Steel mesh grille and plastic gasket included.
