K-Array Concert Series KH4 Self-Powered Line Array Element, 80Hz-20KHz Frequency Range

The K-Array KH4 is a self-powered, 2-way line array design speaker system. At just over 100 lbs (47 Kg ) and 6" depth (16 cm) its ultra-compact aluminum enclosure contains an incredible reserve of power that ensures very high sound pressure with wide, consistent (120deg.) horizontal coverage and the unique capability for varying the vertical coverage from 7deg. for line array applications to as wide as 37deg. for single speaker systems. This provides for an incredibly versatile and flexible cost-effective inventory.

The KH4 is best suited for medium to long throw applications in theatres, concert halls and churches and for corporate AV events. The KH4 easily integrates with other K-array products such as the KS4 large format bass line array element, or KH15 satellites. Bass response and output capability can be extended with the incorporation of the KO70 or KO40 powered sub bass cabinets.

The KH4 uses twelve 8-inch cone drivers with 2.5" voice coils for low-mid frequencies, powered by six power amplifier channels. The mid-high frequency section uses five 1.75" voice coil compression drivers mounted on 1"x 4" constant directivity waveguides. The drivers form an array exactly in the centre of the speaker. A mechanical system can provide different vertical coverage from 7deg. to 37deg. on each KH4. An internal DSP module provides configuration presets. Dedicated remote control software allows for control of the speaker from a PC.
