The KSN1188A driver is designed to provide mid-range and high frequency response along with high power handling. Featuring a standard 1 3/8”-18 UNEF2A thread coupling, it can be easily used with most standard horns. The driver is well suited for pro sound and other sound reinforcement applications. The 100-watt driver incorporates protective circuitry which allows it to be used safely at continuous power levels of 400 watts.
