Monitor Audio WSS430 in Wall Speaker (Each)

Our Price £429.00 RRP £475.00 Save: £46.00
The Monitor Audio WSS430 In-Wall Speaker is the super-slim flagship model, offering high-end performances for both music and movies, with 3 x 3 inch C-CAM bass-mid drivers and a MPD High frequency transducer whilst still being just 50mm deep for easy wall mounting.

The WSS430 flagship maintains a shallow depth while offering a supreme audio performance, inspired by Monitor Audio Platinum II high end speakers. Three dished 3 inch Ceramic-Coated Aluminium/Magnesium cone material is used for the bass-midrange speakers, for ultimate diaphragm rigidity, reducing distortion from the speaker. For an incredible driving force, neo magnets and larger voice coils are used, also providing low magnetic leakage and a slim profile. The magnetic system is designed to provide an ‘under-hung’ motor arrangement, making sure the coil stays in the gap, to reduce distortion and increase power handling.

The high frequencies are handled by the WSS430’s MPD high frequency transducer technology, first used in the flagship Platinum II designs. This top-of-the-range design ensures for low distortion for frequencies up to 50 kHz, giving clear and crisp top end detail. The tweeter can be rotated if the speaker is fitted in a landscape orientation, for the best dispersion of sound.

The WSS430 in-wall speaker is designed to be slim enough to fit in 2 inch stud walls, or when placed landscape the speaker fit between two standard 14 inch stud bays for the most flexible placement options. A magnetically attached trim-less grille forms an easy covering for a discrete look, and is paintable to blend easily with any décor. Tri-Grip Dog leg fixings provide a reliable and robust fixing, and make the WSS430 quick to install. With the WSS430 installed, it works ideally for a discrete stereo speaker, or as part of a larger setup for home cinema systems, either as a rear surround, or a highly capable front speaker.
