Martin Audio SXC115
Compact, High Performance
15" 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 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.
The enclosure is constructed from birch ply 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. 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 loudspeaker.
The addition of the input cover accessory makes the SXC115 weather resistant and suitable for outdoor usage.
