Martin Audio SXC118
Compact, High Performance
Cardioid Subwoofer
Description
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.
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, turntables and walls as well as reducing reverberant energy in the room, greatly improving the system’s 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 plywood and finished with a hard-wearing textured paint. It is equipped with four grab handles and foam-backed perforated steel grilles protect the front and rear drivers. It can be used individually, stacked or flown individually by means of threaded flying inserts.
The SXC118 is an ideal partner for WPM and WPS line arrays or our range of point source loudspeakers where low frequency pattern control is required. 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 singular point source enclosure. The product is supplied as standard without castors but they can be purchased as an accessory.
By adding the input board cover accessory, the subwoofer is fully weather resistant and suitable for permanent outdoor usage.
