YAMAHA IS-1218 Passive Subwoofer 18″ 1400 watt

Yamaha\'s new Installation Series Speakers address a number of important issues that give them unprecedented performance and handling characteristics for live sound applications, including permanent installations. In particular, phase characteristics have been kept smooth and consistent throughout the entire series, so you can mix and match speakers to suit any system and venue without ending up with hot and dead spots due to phase interference. And of course sonic quality is superb throughout the entire reproduction range so the full impact of the source material reaches the audience undiluted.

The Sub 2.18 is a double 18“, high-power subwoofer for very high sound pressure levels: sensitivity 102 dB 1W / 1m, max. SPL 138 dB.

Boasting power handling of 1000W continuous and 4000W peak, the Sub 2.18 can be used universally for active two-way or three-way systems.

It is above all, however, the ideal companion to the C 25.2 for the creation of an active two-way system together with the DSP 260 or DSP 600 controllers and power amplifiers from the SL or LX series.

For easier transport, the Sub 2.18 is prepared for the optionally available DC-WK-C18 wheel kit.

The new Yamaha CW218V features a super durable, paintable, elastomeric-sprayed coating with foam lined acoustically transparent steel grilles. Gives a great professional look much preferred over carpeted enclosures. Assembled by hand in the US by skilled technicians, each cabinet is designed for better low-end response and includes heavy steel handles and sturdy pole sockets to make moving and positioning easy.

The custom drivers from Eminence feature high-strength curvilinear cones and Kapton® voice coil formers, plus oxygen-free copper voice coils and oversize strontium ferrite magnets to provide high power handling and long life. 15" and 18" drivers use cast aluminum frames to support the massive magnet structure, eliminate flex, and dissipate heat. The titanium diaphragm compression driver is mated to a 90 degree x 40 degree custom-designed horn. Internal electronics feature an over-built crossover network and overload protection.

Connections are dual Neutrik Speakon® and 1/4" jacks. With professional features, excellent sonic performance, and great value, Club Concert Series loudspeakers deliver premium quality night after night.
