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
