SXCF115 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. 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 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, delivering 137dB peak, an extra 2dB of output when compared with a conventional 1 x 15” subwoofer.
The SXCF115 integrates perfectly with WPM flown line arrays and TORUS 8 constant curvature arrays, as well an accompaniment for Martin Audio point source systems where low frequency pattern control is required. It can be used singly, stacked or flown, supported by accessories.
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.
The addition of the input cover accessory makes the SXCF115 weather resistant and suitable for outdoor usage.
Martin Audio SXCF115
The loudspeaker shall be a compact cardioid subwoofer consisting of a 15” reflex-loaded transducer radiating to the front of the enclosure and a 12” reflex-loaded transducer radiating to the rear. The transducers shall be driven independently by separate channels of a dedicated controller amplifier.
Power handling of the 15” transducer shall be 1000W AES, 4000W peak and power handling of the 12” transducer shall be 800W AES, 3200W peak. Rated impedance of each transducer shall be 8 ohms. The on-axis frequency response shall be 44Hz- 150kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 137dB peak calculated at 1 metre.
The loudspeaker enclosure shall be constructed from multi- laminate birch ply with a textured coating. The drivers shall be protected by a perforated steel grille and the enclosure shall be fitted with a threaded pole-mount plate, bar handles, skids and support for flyware. The rear connector panel shall be fitted with two NL4 type connectors.
