The drivers, or speakers in these cabinets, are custom made my Eminence Speaker Corporation to Yamaha's exacting tolerances. Woofers share design features like high strength curvilinear cones and Dupont Kapton' voice coil formers. Oxygen-free copper voice coils and oversize strontium ferrite magnets are also used to provide high power handling and long life. The 15" and 18" drivers use cast aluminum frames to support the massive magnet structure, eliminate flex and help dissipate heat. The compression driver that generates the high frequency sound uses a pure titanium diaphragm. This 2" dome is one of the largest in its class, allowing for very high output and low distortion, without the aid of cooling fluids. It's mated to a 90 x 40 custom designed CD (constant directivity) horn with excellent dispersion and response.
Crossover networks that divide the signal going to the woofer and compression driver are constructed with oversized coils, high voltage capacitors, and power resistors designed to provide the best possible sound quality and minimize loss. Overload protection is also included to protect the components.
Connections on these loudspeakers are dual Neutrik Speakon jacks for the highest possible strength and current capacity. Two of each connector makes it easy to "daisy chain," or add speakers.
