15-inch Active Subwoofer [MZ-15]

The MZ-15 is a high-performance, high-efficiency 15″ active subwoofer with an environmentally friendly water-based paint finish. It features a built-in Class D dual-channel digital amplifier with DSP, a 15″ high-power, long-stroke driver unit, and a direct-drive cabinet design for powerful low-frequency sound pressure. When paired with L-series line source sound columns, it delivers even more impressive performance. Its unique design, combined with an aviation case (or custom packaging), facilitates easy handling and installation. It is widely used in KTVs, conference halls, auditoriums, multi-purpose halls, banquet halls, lounges, dance halls, and large, medium, and small-scale mobile performances.
