Audison Prima ABPX 10 AS2 Subwoofer Box

High-Efficiency 10-Inch Active Subwoofer with Built-in 400W RMS He-Li Amplifier and OEM Integration
The Audison Prima APBX 10 AS2 is a premium-grade 10-inch active subwoofer developed to deliver powerful, deep bass in compact vehicles or installations where space for a full subwoofer system is limited. Engineered with a high-performance 400W RMS / 800W Peak He-Li Class D amplifier, it achieves up to 90% efficiency by eliminating the need for a traditional voltage booster—thanks to its ultra-low impedance (0.16Ω) dual-coil driver.

The APBX 10 AS2 integrates DBT (Dynamic Bass Tracking) to intelligently manage audio peaks and deliver clean, distortion-free bass even at extreme volumes. The sealed box design is enhanced with 2S² (2 Sides / 2 Sounds) technology, allowing you to choose between Down-Firing for extended low-end performance or Up-Firing for more punch and clarity.

Complete with adjustable bass boost, low-pass filter, phase control, and multiple input options, this subwoofer is ready for OEM or aftermarket integration. Plug & Play terminals (SSP) and HRC AP remote control ensure fast installation, real-time tuning, and flexible user control.

Key Features

Amplification & Sound Performance

• 400W RMS / 800W Peak built-in He-Li (High Efficiency / Low Impedance) Class D amplifier.
