WPS USER GUIDE

Low Frequency Extension

SXC118 and SXCF118

Designed for touring sound and installations, the SXC118 and it’s flown variant, the SXCF118, is a compact, high performance cardioid
subwoofer. It features an 18” (460mm) forward facing driver and a 14” (356mm) 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, 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.
