Features 2200W Two Way Amplifier 137 dB Max SPL 48 kHz, 32 bit DSP processing 1.4" Titanium Compression Driver, 4.0" voice coil 2 x 10" Neodymium Woofers, 2.5" voice coil Exclusive FiRPHASE technology on-board RDNet Control and Management 680 Hz Crossover Point The RCF HDL30-A is a compact bi-amped 2-way active touring system for medium to large events, both indoors and outdoors. It features two 10-inch woofers and an impressive 4-inch titanium compression driver. The time coherent waveguide is the result of in-depth research and design. HDL 30-A is the first line array in a composite cabinet with zero-degree phase and ultra-linear amplitude response. The built-in 2200 watt class-D amplifier delivers excellent playback clarity and up to 137 decibels SPL max. The RCF HDL30 -A features state of the art RCF transducers with neodymium magnets. Considering its acoustical power, it has a remarkably low weight for easy handling and flying. The HDL 38-AS is the ideal flyable bass complement for the HDL 30-A array system Neodymium RCF precision transducers High frequencies - Superior compression driver with extreme precision in high frequency reproduction.
