Monitor Audio: deep bass for walls of sound12 February 2015
A flexible in-wall subwoofer designed to add deep bass frequencies to architectural speaker systems is on show at Monitor Audio’s stand. The system is an amalgam of the IWS-10 subwoofer driver, IWA-250 amplifier and IWB-10 back box.
The company says the IWS-10 subwoofer driver generated excellent bass depth with maximum installation flexibility. It employs a 10in highly rigid, surface of 10mm Rigid Diaphragm Technology (RDT) material. RDT 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 and 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 improving heat dissipation.
The company says the IWS-10 has been specified to produce excellent bass quality in a range of wall, ceiling, and even floor locations, ideally but not exclusively with its IWB-10 back box, so introducing wider retrofit possibilities.
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, offering better overall surface sealing. The IWS-10’s trimless 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. The IWB-10 is a sealed pre-construction back box, built from MDF and laminated with a rugged black Sandex vinyl finish.
With an internal volume of 24l, it is designed to fit between standard 14in stud spacing and comes supplied with adjustable steel fit brackets. The IWA-250 switch mode amplifier will power single or dual IWS-10s, delivering up to 250W into 4ohms and comes in a heavy-duty 1U rack mount case.
