The S112V is a trapezoid design cabinet, with oversize steel handles, steel corner protectors, steel jackplate with both dual Speakonâ and high current, heavy duty Switchcraft® 1/4" jacks, and a built-in pole socket (1 3/8") for easy stand mounting. The woofer, or low frequency driver is a high power, custom design. The High frequency driver is a custom, 2" diaphragm (1" exit) design with an exclusive phase plug that reduces harmonic distortion inside the driver itself. This driver is mated to a Yamaha designed 90° x 40° constant directivity horn to give smooth, even coverage over the pattern of the horn. Both of these drivers are custom made for us by Eminence®. The internal passive crossover has protection circuitry to help guard against damage that may occur from over powering the S112V. This loudspeaker is manufactured in the USA. It is covered by a 3-year warranty.
