The SL2-F loudspeaker is a fully horn-loaded cabinet made for applications where directivity and power are of utmost importance. Top sound quality : the SL2-F system is a processor controlled 2 way active design, LO & MID/HI. The SL2-F uses two proprietary 12 inch low frequency cone driver house in a horn-loaded enclosure and a 1,4 inch high frequency driver loaded with a 70° x 40°CD horn. The drivers are acoustically aligned at the same vertical plane producing thus an astonishing flat and smooth frequency and phase response from 40Hz to 20KHz. With a cut-off frequency of 40HZ, the SL2-F can be used as a stand alone full range cabinet, or can be associated with the SUB800 or SUB1000 subwoofer to extend the low frequency response of the entire sound system.
