MZ-15 | 15″ Powered Subwoofer

Product Overview

The MZ-15 is a high-performance, high-efficiency 15″ 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 15″ driver in a direct-radiating cabinet structure, delivering powerful and impactful low-frequency sound pressure. When paired with the L-Series 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.

System Configuration:
This amplifier module is integrated within the subwoofer cabinet. It provides two 600W channels at 8Ω. One 600W channel drives the internal 15″ subwoofer. The other 600W channel, via limiting, delivers appropriate power to drive the matched column speaker(s).
