118Sa is a compact, exceptionally powerful active touring subwoofer, created as a core component of the AUDIOFOCUS ARRoCC constant curvature loudspeaker system.

The subwoofer houses a next-generation 18” neodymium LF transducer. Tetracoil Double Voice Coil technology allows 118Sa to achieve best-in-class SPL for its size while ensuring exceptional efficiency and clarity.

118Sa is equipped with an AUDIOFOCUS A4M SCiO Class-D amplifier module with comprehensive integrated DSP. The amplifier can be remotely monitored and controlled via a browser-based WebUI.

118Sa can be used standalone or stacked and can be flown with CC210Wa and CC210Na cabinets using the ARRoCC flying frame accessory.

All AUDIOFOCUS loudspeakers are built in Belgium by skilled craftspeople and state-of-the-art machinery before being coated in tough, weather-resistant polyurea to safeguard your investment.
