1×15″ Compact High Performance Cardioid Subwoofer

SKU 26620 Categories , Tags ,


Designed for touring sound and installations, the SXC115 is a compact, high performance cardioid subwoofer. It features a 15” (380mm) forward facing driver and a 12” (300mm) rear facing driver, each driven independently by separate amplifier channels and DSP. Each driver has its own chamber with optimised bass reflex porting

The SXC115 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 low frequency response accuracy and impact of the whole system. 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 15” subwoofer.

The SXC115 is an ideal partner for WPM line arrays or Martin Audio point source systems where low frequency pattern control is required. It can be used singly, stacked or flown individually by means of threaded flying inserts.
