Audison Prima

Audison Prima was designed to meet the interest of the car model enthusiasts who like to appreciate all the nuances of the musical message with components that are perfectly integrated in the car OEM system, preserving the most precious Prima on Audison requirement of OEM integration: space.

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. 

• 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.

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.
