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

The APS 10 D is designed to deliver maximum performance in a sealed enclosure with ultra-compact volumes, from 10 lt. to 12 lt. The dual voice-coil and single voice coil versions feature push connectors for ease of wiring and configurations. Prima subwoofer components have been developed with a primary goal: to deliver high output in tight spaces. Output is a matter of excursion; the more air the cone moves, the more output. However reduced mounting depth traditionally has meant low excursion. Prima subwoofers employ a special cone-dustcap-basket geometry which guarantees large excursion of the mobile group, while keeping the mounting depth to a minimum. The surround and spider have been carefully designed to prevent the rocking-mode phenomenon. The cooling circuit has been designed with air vents on the basket underneath the spider, eliminating the need for vents on the bottom-plate. This allows the subwoofer to be mounted close to the back wall of the enclosure, making the most of the reduced mounting depth.

Features

  • 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.
