The SL2-F-amp loudspeaker is a powered version of the SL2-F loudspeaker system wich is a fully horn loaded cabinet made for application where directivity and power are of importance. The SL2-F-amp uses two proprietary 12 inch low frequency cone driver housed in a horn loaded enclosure and a 1,4 inch high frequency driver loaded with a 70° x 40° CD horn. The SL2-F-amp is easily arrayable with its 8.5° trapezoidal shape and Ltrack rigging flying hardware.
