Audison Prima APS-8D User Manual

APS 8 D SUBWOOFER

1 Ultra-low prole (3.11 in. / 79 mm) for maximum installation

flexibility.
2 Designed to deliver maximum performance in a sealed enclosure
starting from 7.5 lt.
3 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.
4 Air vents on the basket underneath the spider, eliminating the
need for the central pole vent allowing mounting close to rear wall
of enclosure.
5 Massive motor assembly optimized with FEM (Finite Element
Modeling) for perfect control under high power, high excursion
conditions.

6 Water-repellent treated paper 8 in. cone featuring a prole

developed with simulation and optimized with the Klippel Scan
Vibrometer.

7 Dual voice coil design specically 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) ampliers.

8 Steel mesh grille and plastic gasket included.
