Martin Audio announces two high-performance cardioid subwoofers

Martin Audio SXCF118

Martin Audio has announced the release of two new compact, high performance cardioid subwoofers, the SXCF118 and the SXC115, suitable for both live sound reinforcement and fixed installations.

The SXCF118 is a flyable version of the SXC118 released last year and has been purpose designed to accompany the WPS optimised line array system, while the ground stack SXC115 is set to partner WPM.

The SXCF118 combines maximum low frequency output with exceptional pattern control.
It features an 18” (460 mm) forward facing driver and a 14” (356 mm) rear facing driver, each driven independently by separate amplifier channels and DSP. Each driver has its own chamber with optimised bass reflex porting.

This arrangement produces a cardioid dispersion pattern which maximises the front radiation, while reducing unwanted radiation behind the subwoofer.
The recommended iK42 amplifier optimises the DSP parameters for front and rear drivers to maximise the rear rejection from 21 dB at 43 Hz to 28 dB at 75 Hz.

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 2 dB 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, while foam-backed perforated steel grilles protect the front and rear drivers.
Integral flying hardware, coupled with the WPSGRIDT touring flying frame, allows the SXCF118 to be incorporated at the top of a WPS array, or flown as a separate array alongside.

The SXC115 follows similar principles and contains a 15” (380mm) front facing driver and 12” (300 mm) rear facing driver, each driven, again, independently by separate amplifier channels and DSP. Each driver, similarly, has its own chamber with optimised bass reflex porting.
In front of the enclosure, the output from the two drivers is additive, giving an extra 1 dB of output when compared with a conventional 1 x 15” subwoofer and 21 dB at 43 Hz of rear rejection. It is the perfect accompaniment to WPM or indeed with a pole mount for Martin Audio point source loudspeakers.

Shipping for SXCF118 will begin in May with the SXC115 a month later.
