Part of the Art 7 Series MK4 line of speakers, the RCF ART 745-A MK4 is a lightweight (at 41.5 lb) and portable active speaker designed to deliver full-range sound with accurate high-frequencies, and controlled deep bass. It is well suited for live sound reinforcement or distributed sound systems in clubs, corporate spaces, houses of worship, or for mobile DJ setups. The ART 745-A MK4 is equipped with a 1400W peak, Class-D digital amplifier, which drives 1000W into the 15", neodymium woofer and 400W into the 1.4", titanium compression driver. The speaker delivers a frequency response of 45 Hz to 20 kHz with a peak SPL output of 132 dB, and wide, 90°H x 60°V coverage angles. The driver features a 4.0" voice coil, perfect for a crossover point at only 650 Hz, which allows for better impulse response, fast decay, and superior efficiency. The integrated DSP manages the loudspeaker processing, including crossover and EQ, soft limiter, and dynamic bass boost. Phase and amplitude are corrected using proprietary FiRPHASE technology conceived for delivering a natural and transparent sound, with a balanced stereo image. Easy to operate, the ART 745-A MK4 comes with XLR and 1/4" balanced/unbalanced inputs for connecting a microphone, mixer, or audio device, and with a volume knob to set the level. Furthermore, the switchable Flat/Boost mode enables you to emphasize the bass response when playing at low volume, or keep it flat for all other applications. The cabinet is molded with rugged polypropylene composite material (PP), and designed to dampen vibrations, even at maximum volume settings. It features a top, and side handles, which allow you to firmly hold the speaker, and move it easily. The ART 745-A MK4 can be mounted on a stand or a subwoofer pole, or positioned on its side to serve as a wedge monitor.
