The SXCF118 is a compact, high performance cardioid subwoofer. The flown version of the SXC118, it is the ideal partner for flown WPS or TORUS T12 arrays — combining maximum low frequency output with pattern control. It features an 18” (460mm) forward facing driver and a 14” (356mm) rear facing driver, each driven independently by separate amplifier channels and DSP. Each driver has its own chamber with optimised bass reflex porting.
Features
- Compact, cardioid flown subwoofer
- Front facing 18” (460mm)/4” (100mm) voice coil driver
- Rear facing 14” (356mm)/3.5” (88mm) voice coil driver
- Cardioid dispersion pattern
- 28dB rear rejection at 75Hz
- High output capability
- Tour-grade plywood enclosure
Applications
- Live sound reinforcement
- Fixed installations including live event venues and nightclubs
- Theatre sound
- Corporate AV events
Each driver has its own chamber with optimised bass reflex porting. This arrangement produces a cardioid dispersion pattern which maximises the front radiation and reduces unwanted radiation behind the subwoofer.
This arrangement produces a cardioid dispersion pattern which maximises the front radiation and reduces unwanted radiation behind the subwoofer. The recommended iK42 amplifier optimises the DSP parameters for front and rear drivers to maximise the rear rejection — from 21dB at 43Hz to 28dB at 75Hz. This keeps low frequencies away from stages and walls as well as reducing reverberant energy in the room — greatly improving low frequency response accuracy and impact.
In front of the enclosure, the output from the two drivers is additive, giving an extra 2dB of output when compared with a conventional 1 x 18” subwoofer.
The enclosure is constructed from tour-grade plywood and finished with a hard-wearing textured polyurea coating. It is equipped with four grab handles and foam-backed perforated steel grilles protect the front and rear drivers. Integral flying hardware, coupled with the WPSGRIDT, allows the SXCF118 to be incorporated at the top of a WPS or TORUS T12 array, or flown as a separate array alongside. Interlocking skids prevent movement when stacked and a threaded plate in the top surface facilitates pole-mounting of up to 4 WPM enclosures or a single point source enclosure.
The addition of the input cover accessory makes the SXCF118 weather resistant and suitable for outdoor usage.

User guideMartin Audio SXCF118
The loudspeaker shall be a compact cardioid subwoofer capable of being ground-stacked or flown. It shall consist of an 18” reflex- loaded transducer radiating to the front of the enclosure and a 14” reflex-loaded transducer radiating to the rear. The transducers shall be driven independently by separate channels of a dedicated controller amplifier.
Power handling of the 18” transducer shall be 1000W AES, 4000W peak and power handling of the 14” transducer shall be 800W AES, 3200W peak. Rated impedance of each transducer shall be 8 ohms. The on-axis frequency response shall be 43Hz- 150kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 140dB peak calculated at 1 metre.
The loudspeaker enclosure shall be constructed from multi-laminate birch ply with a textured polyurea coating. The rear connector panel shall be fitted with two NL4 type connectors. The drivers shall be protected by a perforated steel grille and the enclosure shall incorporate an integral rigging system to assemble an array of up to 16 enclosures suspended from a dedicated flying frame. The enclosure shall also be fitted with a threaded pole-mount plate, bar handles and skids.
Dimensions including skids and castors (W x H x D) shall be 650mm x 611mm x 940mm (25.6in x 24.1in x 37.0in). Weight including castors shall be 78kg / 172lbs.
The loudspeaker shall be the Martin Audio SXCF118.
