Designed for touring sound and installations, the SXCF115 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. 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 44Hz 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 15” subwoofer
The SXCF115 features two drivers, a 15” front facing driver and the rear facing 12” driver used to achieve a cardioid response. Connection is made via two NL4 connectors which are wired in parallel. Although these are nominally labelled ‘INPUT’ and ‘LINK’, either connector can be used to connect to the sub or to link out to a second speaker. The Front 15” driver is connected to pins 1+/-, the rear 12” driver to pins 2+/-. A 4-core NL4 cable must be used. If using the recommended iK42 amplifier, connection can be made to output NL4 1 or 3 as these also carry the output signal from channels 2 and 4 respectively to power both drivers
