Three-way active monitor with unique cardioid characteristic in the range from 35 Hz - 300 Hz, minimising reflections from rear walls of listening rooms and excitation of room modes. The mid- and high-frequency range unit is arranged coaxially with the long-throw bass driver and has a directivity index that supplements the bass system superbly. The high-power long-throw bass driver is in a compact enclosure to achieve optimum impulse behaviour Power dispersion optimised for Nearfield monitoring with narrower positioning. Especially interesting for OB van applications Skilful design achieves convincingly low levels of non-linear distortion and coloration, and the system provides superior localisation behaviour. Fitted with a 3 channel integrated MOSFET amplifier and electronic crossover. An intermittent LED signals when the overload limit is reached. Beyond this the output level is reduced by 20dB to avoid component overload. Infinitely variable low frequency controls are supplied for the two adjustable frequency ranges to match transfer characteristics to room acoustics.
