RCF NXL 24-A MK2 Powered Speaker. A line array column speaker called the NXL 24-A MK2 was expertly developed from the bottom up to provide outstanding audio performance for bands, DJs, clubs and rental businesses. Premium RCF transducers and a 2100W two-channel amplifier work together to create the best-in-class coherent 100° x 30° coverage for the listening area with up to 132 dB. Four 6" neodymium woofers and a 3" driver are mounted on an asymmetrical waveguide in the two-way configuration. The horn's construction avoids tilting the enclosure while delivering precise sound to the coverage area. The speaker can be flown, used as a stand-alone speaker, or combined with another NXL 24-A MK2 for greater coverage. It delivers an enhanced frequency range down to 60 Hz.
