ART715A Mk4 is a nicely balanced, yet very powerful active PA speaker. With 500w going to its 15″ woofer and an impressive 200w to the 1″, this little speaker certainly packs a punch – 130 dB worth of punch! Use ART715A Mk4 as a high-powered stage monitor (for larger stage layouts), DJ booth monitor, or as part of a complete Front-of-House system. It’s a multi-purpose speaker that represents the best choice for situations in which a full frequency range with punchy bass and high definition is needed. Maybe it’s the FiRPHASE RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener.
