CPS-18SP
Subwoofer unit in band pass configuration
Compact & extremely powerful, passive subwoofer unit in band pass configuration. 18″ (4″ voice coil) neodymium transducer.
Description
The CPS-18SP is a high-output, extremely powerful sub-bass element designed to be used in unison with the coaxial CPS-214P point source module.
It uses one low distortion 18″ (4″ QUATTRO in/out copper voice coil) custom speaker with FEA optimized ceramic magnet circuit and Exclusive Malt Cross Technology cooling system. It implements Exclusive NCR (Neck Coupling Reinforcement) and is optimized for band pass configuration.
The extra strong, specially designed internal wooden reinforcements reduce unwanted vibrations eliminating any noise, lowering distorsion 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 enclosure is made from premium grade birch plywood and finished with a polyurea coating for longer durability & weather protection.
