Audison APS 8D Prima Series 8" Subwoofer Driver | 500 W Peak Power | 200 mm | 4 + 4 ohm

Product Overview

APS 8 D - SUBWOOFER 200mm 4+4Ohm The APS 8 D is designed to deliver maximum
performance in a sealed enclosure with ultra-compact volumes from 7.5 lt. to
8.5 lt. It features push connectors for ease of wiring and configurations and
has 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 (3.11 in. / 79 mm) for maximum installation
flexibility. Designed to deliver maximum performance in a sealed enclosure
starting from 7.5 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 power, high excursion
conditions. Water-repellent pressed paper 8 in. cone featuring a profile
developed with 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.
