Name: SXP118
Rating: 4.7 (23 reviews)

The SXP118 is a compact, high-performance subwoofer that extends the low frequency operating range of a CDD-LIVE! full-range system to 40Hz — 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 SXP118 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 SXP118 incorporates a Class D amplifier, DSP and Dante™ 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-NET™ proprietary software.

For simple set-ups, ‘plug-and-play’ presets for operation with the CDD-LIVE 8, CDD-LIVE 12 or CDD-LIVE 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 SXP118 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 Zintec grille, twin grab handles, skids, M10 flying inserts and a threaded pole socket.

The product is supplied as standard without cabinet wheels, but they are available as an accessory.

By adding the input board cover accessory, the subwoofer is fully weather resistant and suitable for permanent outdoor usage.
