‘THE OPUS SERIES’

The OPUS is a new series of loudspeakers. They are large format loudspeakers, utilising multi- ple drive units.

The loudspeaker meets the demands of the most discerning audiophile.

These 3 way loudspeakers exhibit exceptional performance characteristics based upon the fol- lowing concepts.

Very low distortion across the entire audio band. Low excursion requirement of the cone drivers.

High flux magnet systems enabling good dynamic response and impulse control. Broadband dispersion for excellent stereo image and staging.

Careful attention to component design, operation, integration and acoustics.

THE CABINET

The enclosure of your speaker is finished to a high-quality furniture standard. Real wood veneers have been selected and carefully patterned matched by hand. Over a period of several days a high gloss ‘Piano’ finish has been achieved. This involves several coatings of lacquers being applied, each being cut and polished before the next coat is applied. Only through this time-consuming and skilled technique, can we achieve the necessary depth and lustre of gloss.

Instead of the usual cuboid shape of speaker cabinet, Opus is built with a beautiful curvaceous design, with a special purpose:- to reduce to negligable levels any internal cabinet standing waves and reflections. Parallel-sided tall boxes promote the creation of acoustic wave formation within the box by reflection up and down the length, these can add and subtract creating anomalies in the forward response. The multiple curved and braced interior of the Opus cabi- net prevents this and results in a much clearer, more precise sound.

Skilfull engineering in ‘MDF’ or Medium Density Fibre Board, universally known to be one of the best enclosures materials, has resulted in an ideally shaped, very strong, internally multiple braced, low resonance structure.
