Castle is celebrating forty years in business with an Anniversary edition and collector’s item, Richmond Anniversary.
Ever since Castle was founded, the Richmond has been the smallest speaker in the Classic range and has defined the Castle sound and quality. Richmond Anniversary loudspeakers offer natural reproduction of musical instruments and voices and according to the recording technique you will hear the full height, width and depth of the original performance.
For this Anniversary issue Castle engineers have investigated every aspect of the Richmond performance to extract the ultimate sound quality from this diminutive monitor-class speaker.
Castle’s woven carbon fibre cone is retained as it offers strength to mass ratio, operating as a pure piston over its pass band. It has a 130mm carbon fibre woven bass unit and a polyamide micro-fibre 19mm dome tweeter. The tweeter has wide bandwidth, with the upper limit of high frequencies extended to well beyond audibility. The use of a simple but thoroughly researched crossover network with Linkwitz-Riley slopes achieves linearity over a wide listening angle. Crossover components have core bass inductors, generously oversized air core inductors and Castle’s proprietary, low-loss polypropylene capacitors.
Input to the crossover and drive units is via updated bi-wire terminals which accept bare wires, spade lugs, pins or 4mm plugs allowing your preference of speaker cable connection. Together with the crossover PCB layout, the bi-wire terminals allow full star grounding back to the amplifier for minimal crosstalk between the split frequency sections.
Additional internal bracing ensures that the dynamic capabilities of the drive units are fully realised. Special attention is also paid to the construction of the grille cover. The frame is composed of two different wood materials for added rigidity thereby minimising any form of resonance.
A touch of luxury is well reflected in the precious Lacewood veneer, specially chosen by highly experienced Castle cabinet craftsmen, some of whom have specialised in selecting the right veneer for each application for more than 30 years, the new Richmond Anniversary will complement conventional to modern room environments.
