In Richmond IV we have taken into account the wider bandwidth of modern recordings, increasing the size of the drive units to deliver a wide range of supreme musical detail, while still keeping true to the 'monitor class' performance for which Richmond is justifiably famous.
The enhanced dynamic capabilities and transient performance of the Richmond IV brings a musical realism and excitement that will have you exploring your musical collection all over again.
Engineered to Perfection
As a start, the cabinet’s behaviour was investigated using the latest vibration and spectral analysis. Richmond’s original 15mm MDF cabinet was later damped by the addition of bitumen damping pads in the 3i in order to reduce the audible effects of panel resonance. For this Anniversary edition, Castle’s engineers reduced panel resonance to below audibility by using multi-layer, composite panel materials and incorporated a loose fibre weave to absorb internal sound waves. In addition, the use of judicious bracing ensures that the dynamic capabilities of the drive units are fully realised.
Fulfilling Acoustic Requirements Without Compromise

Realising the Musical Potential of Modern Hi-Fi Equipment
A larger than usual 6 inches (150mm) bass unit features a newly developed motor system for extreme linearity, midrange precision and profound bass impact, raising sensitivity to a high 88dB. This is married, via a sophisticated but simple Linkwitz style crossover, to a new 32mm treble dome with a rear chamber, providing exceptionally natural reproduction of musical instruments and voices, whatever your choice of music.The enhanced dynamic capabilities and transient performance of the Richmond IV brings a musical realism and excitement that will have you exploring your musical collection all over again.
