The shielded low-frequency driver’s carbon fiber diaphragm remains extremely rigid at high power levels, producing a linear response and low distortion. The cone is fitted with a durable foam surround and treated to resist moisture. The high-frequency section features a 110º x 110º constant directivity horn with a built-in mechanical phase equalizer. The horn is driven by a Ferrofluid cooled, 0.75″ soft dome tweeter.
