The ART 745-A MK4 is the flagship speaker in its category. The titanium dome, 4.0” voice coil neodymium compression driver offers a unique vocal clarity and sound projection. The 15” neodymium woofer offers an extremely linear response and a precise, deep low frequency control. The transducers are produced using the most advanced assembly technologies. The amplifier delivers 1400 watts and is controlled by a DSP that takes care of crossover, equalisation, phase control, soft limiting and speaker protections.
