Audison APS 10 S4S

Subwoofer | 800 W peak power | A mm 250 | 4 ohms.

The compact Prima subwoofer family is expanded with the introduction of the new 25 cm (10 inch) APS 10 S4S, optimized for closed boxes with reduced volume from 10 liters.
The 4 ohm voice coil configuration makes it ideal to be driven by the new AP F8.9 bit amplifier with built-in DSP which delivers an outstanding 260 W RMS with two bridged channels.
Also interesting is the possibility of creating custom boxes with two APS 10 S4S powered by the AP 1D amplifier with 540 W RMS delivered at 2 ohms load as a result of the speakers being connected in parallel.

Features:

Ultra-low profile (120 mm) for maximum installation flexibility.
Designed to deliver maximum performance in a closed box from 10 liters.
Specially designed cone, dust cover and cage geometry ensures long linear stroke (11 mm, single path) while keeping mounting depth to a minimum.
Air vents in the basket under the spider eliminate the need for a central pole vent, allowing for mounting close to the back wall of the cabinet.
Massive motor system, optimized with FEM (Finite Element Modeling) for perfect control at high power and long stroke.
Water-repellent treated 10-inch paper cone, developed with FEM simulation and optimized with Klippel Scan Vibrometer.
Single voice coil, specially developed to be combined with the AP F8.9 bit (2 CH bridged 260 W RMS) amplifier, which utilizes bass boost and the integrated parametric equalizer in the built-in DSP.

Steel mesh grill and plastic gasket included.
