HPCM High Performance Control Monitor



Of compact dimensions and no compromise construction the HPCM is a loudspeaker possessing accurate phase response, remarkably extended frequency response and high power handling capability.

The dimensions of the enclosures have been carefully selected to avoid internal reflections. The narrow baffle with reverse angled edges minimizes edge defraction and secondary radiation. High power handling capability has been achieved by a use of the massively constructed styrene and fibreglass coned woofer in the sealed enclosure, combined with ferrofluid damping of the mid-range and tweeter units. Both the mid-range and bass unit have their rear radiation absorbed in separate and tapered cabinet sections. An in-line configuration of drive units produces precise and stable stereo imagery. A full third order crossover rejects inter-driver coupling, whilst maintaining an accurate transfer function and presenting a smooth impedance curve to the amplifier.

This visually attractive compact loudspeaker, fulfills all the requirements of a high-level monitoring system. It offers uncompromising performance and will accurately reproduce all material of the widest dynamic range.
