MZ-12 | 12″ Powered Subwoofer

Product Overview

The MZ-12 is a high-performance, high-efficiency 12″ active powered subwoofer. Finished with an environmentally friendly water-based paint, it features a built-in Class D dual-channel digital amplifier with DSP. Its design incorporates a single high-power, long-excursion 12″ driver in a direct-radiating cabinet structure, delivering powerful and impactful low-frequency sound pressure. When paired with line source column speakers, its performance is truly remarkable. The uniquely designed accompanying flight case (or custom packaging) facilitates easy transportation and installation. It is widely suitable for applications such as KTVs, conference halls, auditoriums, multi-function rooms, banquet halls, chill-out bars, dance halls, and small to large-scale mobile events.
