The Windsor Duke is equipped with an 8” woofer, purposely-developed together with a 28mm textile dome tweeter, to perform seamlessly in a classic bookshelf / monitor styled cabinet.
The drive units have all been engineered from the ground up, using cast alloy components, yet retaining the essential character through the use of new woven Polypropylene cones and glass-fibre voice coils.
The cabinet work is, as you would expect from a product bearing the Castle name, first class. The hand-selected, book-matched pairs of veneers are sourced from the original suppliers to ensure continuity in the Castle legacy. Our dedicated ‘hand – finished’ team is trained to deliver the highest quality ‘furniture – grade’ finishes and build. No two pairs are the same!
Castle are proud to announce the Windsor Series, signalling the return to the UK for the manufacturing of Castle Loudspeakers. Castle Windsor Series comes, with the craftsmanship and quality that is self-evident and clearly marks the brand’s intention to restore and build upon the reputation of the brand for superlative quality loudspeakers.
Echoing the origins of the brand that was established in 1973; the speakers are hand built and hand finished, by our loudspeaker production experts, in England.
To ensure the Windsor Series is truly something special, Castle has harnessed the talents of world- renowned speaker designer Karl-Heinz Fink and his Fink Audio team. Built over decades, Fink’s track record of developing excellent loudspeakers is exceptional, He was recently described as “today’s most influential speaker designer” when presented with the Outstanding Contribution Award at the What Hi-Fi? Awards 2022 – a fitting tribute to the success of his designs.
The Polypropylene used in the cones is precision cut into thin strips, woven back into a sort of fabric and comes together again to form a solid foil. This foil gets pressed into the final shape and then cut to size.
This is a much more complex way of creating a polypropylene cone, but it has significant sonic benefits. The process creates a material with different properties of rigidity, at different directions between the voice coil and the surround. This helps to minimise resonances, which produces a flatter response curve – a desired characteristic of any drive unit designed for high-performance audio.
The resulting cones, with a diameters of 200mm, feature surrounds fashioned from low-hysteresis rubber which will not deteriorate over time.
The magnet system in the Castle Windsor Series includes an aluminium compensation ring. This ring helps minimise the variation of the impedance during the operation of the drive unit. As a result, the harmonic and intermodulation distortion values are reduced, for improved openness of the midrange performance.
The voice coils are made from glass fibre, bonded with high-temperature resin – the stiffness and rigidity of this material is extremely close to that of aluminium, but it doesn’t generate eddy currents like aluminium would. Thus, it maintains signal purity by its very design. The mid/bass drivers’ magnet system includes an aluminium compensation ring, which helps to minimise impedance variations during operation. As a result, the harmonic and intermodulation distortion values are reduced, contributing greatly to an open and expressive midrange performance.
