Since 1973 Castle has been a loudspeaker manufacturer in the truest possible sense with both design and manufacture of their world famous speakers housed entirely in one factory. Castle is rare amongst loudspeaker manufacturers in that they not only manufacture the drive units and electronic components found in their speakers but also the beautifully hand crafted real wood veneered cabinets used to enclose them.

30 years ago when Castle was formed the founding concept was to be a complete loudspeaker manufacturer and despite changing times and the globalisation of manufacturing Castle still retain this as the basis for the company.

Castle Acoustics is now part of the International Audio Group and maintains its position as a leading Hi-Fi brand in the international market through innovative ideas and impeccable craftsmanship. Castle  products are developed through sophisticated research in acoustics engineering, while retaining the traditional virtues of impeccable design and presentation – a perfect balance of form and function.

Whether it be our superb hand finished real wood veneered cabinets, available in eight alternative choices, or our state of the art woven carbon fibre coned bass units that first attracted you to the Castle product you can be sure that they were manufactured by Castle, the world's most complete loudspeaker manufacturer.

 Richmond Anniversary

The Richmond Anniversary is Castle’s smallest and first loudspeaker to redefine studio monitor sound and furniture quality craftsmanship. It offers exceptionally natural reproduction of musical instruments and voices across all musical genres. Its enhanced dynamics and transient capability bring musical richness and excitement that will have you exploring your entire music collection.

Castle engineers succeed in reducing panel resonance to below audibility by using multi-layer, composite panel materials, a loose fibre weave and bitumen damping pads to absorb internal sound waves. Additional internal bracing ensures that the dynamic capabilities of the drive units are fully realized. 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.

The new Richmond Anniversary employs a 130mm carbon fibre woven bass unit and a polyamide micro-fibre 19mm dome tweeter. The bass driver operates as a pure piston over its pass band and offers a remarkable bandwidth and superb dynamic performance. The tweeter has exceptionally 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 superb 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.

Beautifully veneered in real lacewood, specially chosen by highly experienced Castle cabinet craftsmen, some of whom have specialized in selecting the right veneer for each application for more than 30 years, the new Richmond Anniversary will complement conventional to modern room environments
