Monitor Audio Shadow 50 Loudspeakers

Pair of super slim satellite speakers

The S50 is designed to coordinate with video displays of up to 50". It features dual 4" RDT drivers and a 25mm C-CAM tweeter in a D’Appolito array, augmented on either side by dual ABRs.

Features

• Ultra-slim depth of just 40mm (1½") complements the slimmest TV screens.
• Designed and tuned to provide optimum sound quality when flush wall mounted.
• Black anodized aluminium finish for excellent aesthetic results.
• Easy installation: flat to wall fixings, invisible cable entry/connection and a removable magnetic grille make installation simple and seamless.
• A single alloy extrusion provides a slender profile, maximises the internal cabinet volume and offers high rigidity to suppress resonance.
• A specially developed 25mm C-CAM® tweeter features a unique venting and rear loading chamber for low resonance and clean pure sound down to the low frequency crossover point.
• 4" low profile bass-midrange drivers feature a flat RDT® sandwich diaphragm constructed from C-CAM® and Rohacell materials.
• Unique 'floating' driver mounting reduces colouration: the drivers bolt to the rear of the cabinet and are de-coupled from the baffle at the front in an airtight neoprene seal.
• A special 'concertina' driver suspension design provides high excursion from a low profile assembly.
• 4" low profile ABR drivers are individually tuned, providing punchy bass without the noise associated with ported designs.

Technology

C-CAM® Drivers: Ceramic-Coated Aluminium/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminium/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.

Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range. C-CAM tweeters and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.

ABR: For open environments sound quality can be further enhanced through the use of a sealed ABR (Auxiliary Bass Radiator). The ABR works like a piston moving back and forth generated by the movement of the air via the motion of the mid/bass driver inside the sealed cabinet. This makes the ABR ultimately act like a conventional port resulting in superior low frequency punch and extra penetration whilst keeping the elements at bay.
