Audison AVBX-12-D4-II AVBX 12 D4 II - 300mm 4+4ohm 1100W Sealed Subwoofer Box

Overview

The AVBX 12 D4 II is a compact 12-inch loaded subwoofer enclosure engineered to deliver powerful, controlled low-frequency performance in space-conscious installations. Designed within the VOCE II platform, it combines high output capability with refined bass accuracy for both OEM upgrades and custom systems.

Built around the AV 12 D4 II driver, the system features a dual 4-ohm configuration for flexible integration and consistent performance under demanding conditions.

Feature Highlights

• Ultra-shallow sealed enclosure for compact installations
• Dual 4-ohm voice coil configuration for wiring flexibility
• 550W RMS / 1100W peak power handling
• 2S² dual-orientation design (down-firing or up-firing)
• Sub Smart Plug (SSP) hybrid connection system

Construction & Engineering

The enclosure is constructed from high-density 15 mm MDF and reinforced with internal bracing to ensure structural rigidity and effective damping. This design minimizes unwanted resonance and coloration, resulting in tight, accurate bass reproduction with strong transient response.

The integrated subwoofer utilizes a polypropylene cone with mica injection, rubber surround, and CCAW voice coil on a glass fiber former. A high-density ferrite magnet and optimized motor structure support controlled excursion and reliable performance.

Installation & Integration

The 2S² dual-orientation architecture allows flexible installation in either down-firing or up-firing configurations, adapting to different vehicle layouts and acoustic goals. Its compact footprint makes it ideal for space-limited applications.

The Sub Smart Plug (SSP) terminal enables quick and secure connections through a combination of plug-and-play and traditional push terminals, supporting high-current wiring with ease.
