SXH218

The SXH218 is an extremely powerful subwoofer capable of producing 148dB peak output at 1m. It is the ideal partner for Wavefront Precision WPC arrays where maximum low frequency output is required as well as a standalone solution for premium permanent installations such as nightclubs.

Description

Features

  • Ultra-high output ground-stacked subwoofer
  • Hyid® horn/reflex loading for maximum acoustic efficiency and low frequency extension
  • Dual long-excursion 18” (460mm)/4.5” (115mm) voice coil neodymium drivers
  • Forward or rear-facing operation

Applications

  • Outdoor festivals
  • Stadiums, arenas and theatres
  • Concert halls
  • Nightclubs

Its Hyid® 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.

The enclosure is constructed from multi-laminate plywood and coated with hard-wearing textured black polyurea. A rigid perforated steel grille protects the front of the enclosure, while interlocking skids protect the top and bottom surfaces and prevent movement when stacked.

The SXH218 can be powered by either a single channel of a Martin Audio iK42 4-channel amplifier, or a idged pair if maximum output is required. Its connector sockets are wired so that one four-core cable from the amplifier will power two SXH218’s. SXH218 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.
