The S115V is a trapezoid design cabinet, with oversize steel handles, steel corner protectors, a steel jackplate with both dual Speakonâ and high current, heavy duty Switchcraft® 1/4" input jacks, and a built-in socket for pole mounting. Its covering is tough black carpet, with a heavy gauge perforated steel grille for driver protection. The woofer, or low frequency driver is a high power design using cast aluminum frame, with a cooling port in the pole piece for extended high power handling. 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 90° x 40° constant directivity design 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 S115V. This loudspeaker is manufactured in the USA.
