British High-Fidelity Architectural Sound Redefined

The WSS430 flagship maintains its siblings’ shallow depth—all three feature identical footprints—and offers supreme audio performance, drawing on design principles and materials from Monitor’s Audio’s high-end Platinum II speakers.

The WSS430 range topper employs dished C-CAM cones to ensure ultimate diaphragm rigidity; the main aim here is to reduce distortion. High-strength Neo magnets and larger voice coils provide incredible driving force, low magnetic leakage, and a slim profile. The magnetic system provides an ‘under-hung’ motor arrangement, ensuring the coil stays in the gap, reducing distortion further and increasing power handling.

Still just 50 mm deep, there is a lot going on with the WSS430. The MPD high frequency transducer technology—also from Monitor Audio’s flagship Platinum II designs—ensures incredibly low distortion, delivering clear high frequency to over 50 kHz. Remove the model’s magnetic front trim, and you can rotate the tweeter to provide the optimum dispersion when using the model in landscape orientation.
