CLS 218S

Lynx Pro Audio

Subwoofer 2 x 18″ (45cm) Active 6000W

Subwoofer unit in direct radiation configuration

Compact & extremely powerful, self-powered (6000 W Class-D with PFC), DSP integrated sub-bass unit in direct radiation configuration. Dual 18” (4.5” voice coil) neodymium transducer.


The CLS-218S is a high-output, extremely powerful sub-bass element designed to be used in unison with the coaxial CLS-212 line array module.

It uses two low distortion 18” (4.5” Split winding copper voice coil) custom speaker with double silicon spider with optimized compliance, ventilated voice coil for reduced power compression and aluminium demodulating ring for very low distortion.

Designed to be used either as a standard sub bass unit or easily configurable in cardioid configuration thanks to integrated front & rear power connectors enable a discreet installation without any cables visible at the front of the cluster. The extra strong, especially designed internal wooden reinforcements reduce unwanted vibrations eliminating any noise, lowering distortion and delivering a clear sound. At the same time, the bass port is designed with a flare to eliminate any turbulence caused by sharp edges in the sound waves path.

The 6000W Class-D amplifier with PFC (Power Factor Correction) offers exceptional efficiency with maximum system performance whilst significantly lowering power consumption. With Thermal, short-circuit and overload protections the system module delivers an outstanding sonic performance. Coupled together with our new generation, 64 bit/96KHz processor the system electronics are yet further guaranteed not only the utmost protection but the best performance.

Designed in-house by Lynx Pro Audio engineers our DSP offers the most recent advances in digital processing, delivering a linear phase & frequency response. The latest 32 bit/96KHZ AD/DA converters make the system one of the most advanced & innovative line arrays on the market resulting in superior sound quality.

A 2.8” IPS user interface is located on the enclosure’s back panel and has multifunction joystick control enabling the user to control, select and/or adjust parameters such as cabinet presets, gain, delay and input EQ (see user manual). Two Ethernet ports enable the system to be controlled with the OCS platform for easier alignment, monitoring and processing of the array and together with the new Rainbow 3D prediction software delivers a complete system design tool.

The enclosure is made from premium grade birch plywood and finished with a polyurea coating for longer durability & weather protection. It also has a number of dedicated accessories available.
