The CSX-LIVE 118 is a compact, high-performance subwoofer that extends the low frequency operating range of a CDD-LIVE full-range system to 35Hz - providing exceptional low frequency impact and increasing headroom. It features a long-excursion 18" (460mm)/4" (100 mm) voice coil driver with a water-resistant cone and triple roll surround in a compact reflex enclosure. The design of the 18" driver maximises output while minimising power compression and distortion, and the four reflex ports have a large frontal area to reduce turbulent air noise at very high levels. With a maximum SPL capability of 135dB peak at 1 metre, the CSX-LIVE 118 is the ideal subwoofer for theatre and portable live sound applications, as well as premium installations that require the maximum output from a compact enclosure.

A self-powered system, the CSX-LIVE 118 incorporates a Class D amplifier, DSP and DanteTM digital audio networking - simplifying set-up, enhancing control and eliminating amplifier racks. The onboard amplifier delivers 2000W peak output to the driver, and its switched-mode power supply auto-ranges to global mains voltages from 100 to 240V 50/60Hz. DSP functions - including parametric EQ, delay, muting, gain and preset selection - can be controlled over Ethernet from a PC or Windows® tablet via intuitive VU-NETTM proprietary software.

For simple set-ups, ‘plug-and-play' presets for operation with the CDD-LIVE 8, 12 or 15 - as well as a user-defined preset - can be selected on the rear panel, instead of using computer control. Additional presets provide the appropriate settings for the rear-facing subwoofer in a cardioid pair.

As an alternative to its analogue inputs, the CSX-LIVE 118 is Dante enabled for digital audio distribution and control over a single CAT5 cable to maintain audio quality however long the cable run.

The enclosure is constructed from multi-laminate plywood with a durable polyurea coating and equipped with a perforated steel grille, twin grab handles, skids, M10 flying inserts and a threaded pole socket.
