Funktion one Monitor RM15


The RM15 compact monitor is designed for static stage performer or DJ use. Mid and high frequencies are delivered with exceptional coherence from the 5″ paper cone transducer originally designed for the innovative R1 loudspeaker. The Funktion One designed lightweight Neodymium 15” low frequency driver is incorporated into the enclosures with a special loading technique. This technology results in bass performance normally associated with horn loaded boxes whilst maintaining the size and weight of their ported counterparts.

This product is ideal for use as highly accurate and powerful DJ monitors with their low distortion significantly reducing ear fatigue compared with compression driver based alternatives. The horizontal dispersion of this monitor (in stage orientation) is relatively narrow and so on stage it is at its best with static performers.

The enclosure is provided with an integral 35mm pole mount, so that it can also be deployed as a main PA loudspeaker, and comes complete with a sturdy, foam backed, full metal grille. The RM15 is also available with an optional passive crossover.
