The AVBX 10 D4 II is the compact subwoofer enclosure of the VOCE II line, designed to bring high-end low-frequency performance into tight installation spaces—without compromise.

Its ultra-shallow sealed architecture is engineered to deliver tight, accurate and dynamic bass while preserving valuable in-vehicle space. Built from high-density 15 mm MDF with internal bracing, the enclosure ensures maximum rigidity and effective damping, eliminating unwanted resonances and coloration.

The internal volume and damping are acoustically matched to the AV 10 D4 II subwoofer, which features a dual 4-ohm voice coil for greater wiring flexibility in high-power system configurations. This pairing guarantees seamless integration and controlled low-end response, even in space-limited applications.

Thanks to the 2S² dual-orientation design, the enclosure can be installed in Down-Firing or Up-Firing configuration, adapting to available space and acoustic goals. The Sub Smart Plug terminal combines Plug-&-Play convenience with traditional push connectors, ensuring fast, secure and high-current-ready wiring.

The enclosure’s refined styling reflects the visual identity of the VOCE II speaker line, combining performance and elegance in a single, integrated solution.

Compact, precise and ready to perform, the AVBX 10 D4 II is the ideal solution for adding impactful, controlled bass to OEM or custom installations—where space is limited but expectations are high.
