Martin Audio announced two new subwoofers for its Wavefront precision line of speakers—an ultra-high output subwoofer, the SXH218; and the SXF115, a flyable 15” subwoofer.

SXH218: Ultra-High Output Subwoofer
The SXH218 is a subwoofer capable of producing 148dB peak output at 1m and is the ideal partner for WPC optimized line arrays where maximum low frequency output is required. It can also be a standalone solution for premium permanent installations.

“It looks destined to be the fastest selling subwoofer we’ve introduced in some time,” commented Managing Director, Dom Harter.

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.

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 bridged 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.

The product will ship from April 2018.

SXF115 Flyable 15” Subwoofer for Wavefront Precision
The ideal companion for our new WPM optimized line array, SXF115 can extend the performance down to 42Hz and can be flown as part of an array, or ground-stacked separately. Cardioid operation can be achieved by arranging the SXF115 in forward and rear-facing pairs.

“Wavefront Precision line arrays have sold very successfully and across more varied applications than initially expected. With that has come demand for additional subwoofer solutions," said Harter.

The SXF115 is a passive subwoofer designed to extend the performance of Martin Audio WPM and MLA Mini systems down to 42Hz. Featuring a powerful, long-excursion 15” (380mm)/4” (100mm) voice coil driver in a very compact bass reflex enclosure, it can be flown as part of a WPM or MLA Mini array, or ground-stacked separately.

The design of the 15” driver maximizes output while minimizing power compression and distortion, and four reflex ports reduce air noise at very high output levels. The SXF115 enclosure is constructed from multi-laminate birch ply, finished with a durable polyurethane coating and equipped with a perforated steel grille, skids and twin bar handles. An M20 threaded fitting in the top surface facilitates pole-mounting of up to 4 WPM or MLA Mini enclosures.

Being a passive subwoofer, the SXF115 is ideal for flown WPM or MLA Mini fixed installations where ground-based, rack-mount amplification is preferred — either for ease of servicing, increased IP protection, or reduced visible cabling in the air.

When used with a WPM or MLA Mini array, Martin Audio iKON amplifiers or the MSX rack-mount power plant respectively deliver the correct drive characteristics to the SXF115, with onboard DSP presets for a variety of system configurations. Cardioid operation can be achieved by arranging the SXF115 in forward and rear-facing pairs.
