Martin Audio SXH218, 2x 18" High-Output, Hybrid horn/reflex-loaded Subwoofer. Ground Version Black & White
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” (460mm)/4.5” (115mm) voice coil neodymium drivers, with water-resistant cones and triple roll surrounds. Also available is the Martin Audio SXHF218, a version of the SXH218 with flying hardware. It can be incorporated at the top of a WPL array, or more commonly flown as a separate array alongside. Like the ground-stack version, a combination of forwarding and rear-facing enclosures can be configured with specific directional properties. Also, Both the SXH218 and SXHF218 can be powered by either a single channel of a Martin Audio iK42 4-channel amplifier or a bridged pair if maximum output is required. Its connector sockets are wired so that one four-core cable from the amplifier will power two subwoofers. Subwoofer settings are determined by a pre-determined parameter set in Vu-Net when used in conjunction with iK42, or Settings are available from the Martin Audio website when used with alternative amplifiers. By adding the input board cover accessory, the subwoofer is fully weather resistant and suitable for permanent outdoor usage.
