CLS-218SP
Subwoofer unit in direct radiation configuration
Compact & extremely powerful, 3400W sub-bass unit in direct radiation configuration. Dual 18” (4.5” voice coil) neodymium transducer.
Description
he CLS-218SP is a high-output, extremely powerful sub-bass element designed to be used in unison with the coaxial CLS-212P 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.
Depending on the configuration, the system is amplified with the GTX Series, 4-channel, extremely high power level amplifiers with outstanding, high efficiency. They come equipped with a quality FIR-DSP with high performance 96kHz DSP processing and a large IPS display with a touch panel user interface.
Advanced Audio Power Control Management has been implemented in the design of the GTX series. This enables the user to configure the division of power between the channels via the DSP enabling them to obtain maximum power through just one single channel if desired. Optional Networking AES67 and AES3 Digital inputs are also available.
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.

Hardware for CLS-218SP
 | EnclosureThe CLS-218S cabinet is constructed from 11-ply and 13-ply premium birch plywood (15mm & 18mm thickness). The enclosure is finished with polyurea coating. |
 | Internal designThe internal structure of the CLS-218S is heavily braced for greater longevity and all parts are assembled on metal inserts with metric screws. The amplification modules & DSP are housed in a separate chamber to the drivers avoiding excessive heat & vibration, thus delivering greater efficiency and reliability. |
 | Rear panelThe powder coated steel front panel contains connections to power and signal for cardioid operation. |
 | GrillThe CLS-218S has three heavy duty, powder coated front grille with a special acoustic rear fabric to protect the transducers against dust and dirt. |
 | HandlesThe CLS-218S has six ergonomic handles with firm internal grip, three on each side of the enclosure, to facilitate transport, positioning and loading of the cabinets. |
 | TransportThe CLS-218S has two transport options: front squid cover with wheels (100mm) and a metal transport dolly for up to three CLS-218S enclosures. |
