Audison Prima APS 10 S4S Subwoofer Driver

10-Inch High-Efficiency Subwoofer with 4Ω SVC and Shallow-Mount Enclosure Optimization
The Audison Prima APS 10 S4S expands the Prima compact subwoofer family with a powerful 10” single voice coil (4Ω) configuration, engineered to deliver 800W peak power and maximum performance in sealed enclosures as small as 10 liters. Designed for applications where space is at a premium, this subwoofer features a super-slim 120mm (4.7″) mounting depth while maintaining high excursion and tight low-frequency response.

Its custom cone-dustcap-basket geometry allows for an impressive 11mm one-way linear excursion, moving more air without increasing mounting depth. Engineered with a FEM-optimized motor assembly, this sub offers stability and control even at high power and excursion levels. The water-repellent pressed paper cone, shaped with Klippel Scan Vibrometer, ensures natural, distortion-free bass.

The APS 10 S4S pairs perfectly with the Audison AP F8.9 bit amplifier, delivering 260W RMS in bridged mode—ideal for DSP-based setups with customizable EQ and bass boost. For enhanced bass output, users can wire two APS 10 S4S units in parallel (2Ω load) and drive them with the AP 1D amplifier, achieving up to 540W RMS output.

Designed for both OEM integration and custom installs, the APS 10 S4S includes a steel mesh grille and plastic gasket, ensuring protection and sealing integrity in tight enclosures.
