Martin Audio has announced the release of two new compact 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 WPS optimized line array systems, while the ground stack SXC115 is set to partner with WPM systems.

The SXCF118 incorporates an 18-inch (460-mm) forward-facing driver and a 14-inch (356-mm) rear-facing driver, each powered independently by separate amplifier channels and DSP. In addition, each driver has its own chamber with bass reflex porting, and arrangement that produces a cardioid dispersion pattern that maximizes front radiation while reducing unwanted radiation behind the subwoofer.

The recommended iK42 amplifier optimizes the DSP parameters for front and rear drivers to maximize the rear rejection, stated as 21 dB at 43 Hz to 28 dB at 75 Hz. This helps low frequencies away from stages and walls as well as reducing reverberant energy in the room in order to improve low-frequency accuracy and impact. In front of the enclosure, the output from the two drivers is additive, offering a stated extra 2 dB of output when compared with a conventional 1 x 18-inch sub.

Enclosures are constructed from tour-grade plywood and finished with a hard-wearing textured polyurea coating. They’re 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 SXHF118 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-inch (380-mm) front-facing driver and 12-inch (300-mm) rear-facing driver, each in its own bass reflex chamber and independently powered by separate amplifier channels and DSP. In front of the enclosure, the output from the two drivers is additive, stated as providing an extra 1 dB of output when compared with a conventional 1 x 15-inch sub and 21 dB at 43 Hz of rear rejection. In addition to accompanying WPM, there’s also a pole mount for use with Martin Audio point source loudspeakers.

Martin Audio managing director Dom Harter states, “We were delighted with the response to our initial cardioid subwoofer last year and this has really driven the demand to release these two further products. This also means we have announced 12 new products in the first three months of the year which is a record number of new products for us in such a time frame. We are consistently reviewing the market and our customer needs, and working tirelessly to offer our partners the optimal solutions between technology and price to win in the marketplace.”

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