The SXHF218 is an extremely powerful subwoofer capable of producing 148dB peak output at 1m. It is essentially the flown version of SXH218 and is the ideal partner for Wavefront Precision WPL arrays where maximum low frequency output is required.
Features
- Ultra-high output flown subwoofer
- Hybrid® 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

Martin Audio SXHF218
The loudspeaker shall be a flyable subwoofer consisting of two 18”/4.5” voice coil, long-excursion, low frequency transducers in a hybrid horn/bass reflex configuration. The on-axis frequency response shall be 32Hz-150kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 148dB peak calculated at 1 metre.
Power handling shall be 3000W AES, 12000W peak. Rated impedance shall be 4 ohms. The rear connector panel shall be fitted with two NL4 type connectors and the loudspeaker shall be operated in conjunction with a dedicated controller amplifier.
The loudspeaker shall be capable of forward and rear-facing operation to enable the construction of flown or ground-stacked subwoofer arrays with specific directional properties.
The loudspeaker enclosure shall be constructed from multi-laminate plywood with a textured black polyurea coating. The drivers shall be protected by a perforated steel grille and the enclosure shall be fitted with bar handles and skids.
Dimensions including skids, excluding castors (W x H x D) shall be 1148mm x 604mm x 1027mm (45.2in x 23.8in x 40.4in). Dimensions including skids and castors (W x H x D) shall be 1148mm x 604mm x 1155mm (45.2in x 23.8in x 45.5in). Weight shall be 138kg (304lbs), with castors 146.5kg (323lbs).
The loudspeaker shall be the Martin Audio SXHF218.
