The APS 10 D was designed to deliver maximum performance in a sealed enclosure with an ultra-compact volume of 10 to 12 liters. The dual voice coil and single voice coil versions feature plug connectors for easy wiring and configurations. The Prima subwoofer components were developed with one primary goal: to deliver high performance in a small space. Performance is a matter of excursion; the more air the cone moves, the more output level. However, a shallow mounting depth traditionally means low excursion. Prima subwoofers use a special cone-dust cap-frame geometry that guarantees large excursion of the moving assembly while minimizing mounting depth. The surround and spider were carefully designed to prevent the "rocking mode" phenomenon. The cooling circuit is equipped with ventilation openings on the frame below the spider, so no ventilation openings are required on the backplate. This allows the subwoofer to be mounted close to the enclosure’s rear wall, making optimal use of the shallow mounting depth.

FEATURES

• Ultra-flat profile (120 mm) for maximum installation flexibility.
• Designed for maximum performance in a sealed enclosure with a starting volume of 10 lt.
• Specially developed cone-dust cap-frame geometry that allows long linear excursion (11 mm, one-sided) while keeping mounting depth to a minimum.
• Ventilation openings on the frame below the spider eliminate the need for a central ventilation opening, allowing mounting close to the enclosure’s rear wall.
• Massive motor assembly, optimized with FEM (Finite Element Modeling) for perfect control under high power and large excursion conditions.
• Water-repellent, pressed paper, 10-inch cone with a developed profile using FEM simulation and optimized with the Klippel Scan Vibrometer.
• Dual voice coil design, specially developed for combination 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.
• Includes steel grille and plastic gasket.
