The IWS-10 subwoofer driver employs an extraordinarily rigid, flat 10” surface of 10mm (3/8”) RDT® material derived from Monitor audio’s acclaimed ‘Platinum’ series of high-end speakers. Rigid Diaphragm Technology is a sandwich of C-CAM® alloy, bonded to a honeycomb Nomex core. The resulting properties of low mass and great strength give the driver the ability to behave as an extremely agile piston, resistant to bending, light enough to deliver an accurate bass response through large excursions, even within a shallow 81mm profile. A large vented pole helps to move air quickly, reducing power compression and heat dissipation.
Consequently the IWS-10 is specified to generate excellent bass quality from wall, ceiling, even floor locations, providing a wide range of new and retrofit possibilities ideally but not exclusively with its IWB-10 back box. It features Monitor Audio’s patented Tri-Grip® clamping system which is easier to install and provides three times the surface area of a conventional dog-leg type clamp for better overall surface sealing. The IWS-10’s trim-less grille and frame edge are paintable to blend discreetly with décor. When used with the IWB-10 back box, the IWS-10 will return optimum ‘controlled’ performance.
C-CAM® BASS DRIVERS
Refined over many years by Monitor Audio, Ceramic-Coated Aluminium/Magnesium is used as a driver cone material for all our speaker designs from the mid-market models up. Originally developed by the aerospace industry for jet engine components, C-CAM's properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. C-CAM bass drivers are able to resist the bending distortion imposed by sudden and extreme bass excursions to reproduce very clean, deep and dynamic bass frequencies. Conventional cone materials are more likely to flex in operation, producing a significant level of audible distortion.
RDT is a unique technology developed specifically by Monitor Audio's engineers for the Platinum series of loudspeakers*. Designed to reduce mass and increase cone stiffness, RDT applies ultra-thin skins of C-CAM to a core of honeycomb Nomex®** material, creating a structure which is extremely light but incredibly rigid. At only 40 microns thick, the C-CAM skins are half the thickness of a human hair, yet when bonded to the Nomex core they form an RDT cone, which is 150 times more rigid than a single layer of 200 micron C-CAM alloy, but has a fraction of the overall mass. These properties allow the cone to operate as a lightning-fast piston for a clearer more natural sound. The RDT cone's concave geometry has been refined by FEA analysis to provide a smooth frequency response and to eradicate break-up.
TRI-GRIP® DOG FIXINGS
All models feature a unique Tri-Grip fixing design. This 3-position 'dog' style fixing provides a greater contact surface area than other types, whilst saving installation time. The Tri-Grip fixings are made from a tough re-enforced polymer, giving a secure fixing without the risk of over-tightening.
