Martin Audio SXH218 2 x 18-Inch Passive Hybrid Horn/Reflex Subwoofer: Subwoofer Powerhouse for Maximum Bass Impact
The Martin Audio SXH218 subwoofer redefines low-end performance, delivering earth-shaking 148dB peak output at 1 meter. Ideal for large-scale sound reinforcement applications and premium permanent installations like nightclubs, the SXH218 excels as both a standalone solution or seamlessly integrated with WPS, WPC, and WPL arrays.
Its innovative Hybrid horn/reflex design combines the forceful punch of a bass horn with the extended low-frequency response of a reflex enclosure. This translates to significantly higher output levels compared to traditional reflex subwoofers. The SXH218 boasts a frequency response of 32Hz to 150Hz (+/- 3dB), ensuring powerful and accurate bass reproduction. Dual 18-inch (460mm) long-excursion drivers with 4.5-inch (115mm) voice coils and neodymium magnets provide the driving force behind the subwoofer's exceptional performance. Water-resistant cones and triple roll surrounds ensure reliable operation even in demanding environments.
