Most of the bass units in our range feature cones made from woven carbon fibre, a light yet exceptionally stiff material with good internal damping. Our voice coil formers have exceptional power handling ability, while we also use innovative magnet assemblies with the highest quality copper and aluminium wire.
This means a far more linear motion is maintained, improving accuracy and dynamics, while reducing distortion, the latter results in a reduction of the moving mass of the driver, a vital parameter in producing speakers capable of maximising the impact of modern source components and program material.
We have also designed our tweeters to match the sonic performance of our bass units and so to enhance all musical accuracy of all Castle loudspeakers. They offer extended and substantially flat response characteristics with very low distortion and are married with bass units through crossovers built with the highest quality components.
