The Martin Audio SXH218 is an extremely powerful subwoofer, capable of producing 148dB peak output at 1m. Its Hybrid® horn/reflex loading combines the acoustic efficiency and impact of bass horn technology with the low frequency extension of a reflex design, enabling it to produce significantly higher output levels than a traditional reflex-loaded subwoofer. With an operating range of 32-150Hz + 3dB, it features dual long-excursion 18 inch (460mm)/4.5 inch (115mm) voice coil neodymium drivers, with water resistant cones and triple roll surrounds.
