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 startingfrom 10 lt. Special designed cone-dustcap-basket geometry which guarantees along linear excursion capability (11 mm, one-way) while keeping themounting depth to minimum. Air vents on the basket underneath the spider, eliminating the need forthe 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 developedwith FEM simulation and optimized with the Klippel Scan Vibrometer. Dual voice coil design specifically developed to be combined with eitherAP8.9 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.
