MONITOR AUDIO - IWS-10 / IWA-250 In Wall Subwoofer System

Created to add deep bass frequencies to architectural speaker systems, Monitor Audio’s new InWall Subwoofer design is an amalgam of sophisticated IWS-10 subwoofer driver, IWA-250 amplifier and IWB-10 back box. The in-wall IWS-10 subwoofers are  £350 each and the IWA-250 amplifier is £350 as well, but is capable of driving two IWS-10 subwoofers. An optional IWB-10 back box designed to fit in standard studwork is £150.

The IWS-10 is specified to produce excellent bass quality in a range of wall, ceiling, even floor locations, ideally but not exclusively with its IWB-10 back box, 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 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. The IWB-10 is a sealed pre-construction back box, built from MDF and laminated with a rugged black Sandex vinyl finish. Having an internal volume of 24 litres, the IWB-10 is designed to fit between standard 14” stud spacing and comes supplied with adjustable steel fixing brackets. While providing the ideal environment for the driver, the IWB-10 will also reduce the radiation of sound to adjacent rooms. For easier installation, the IWB-10 is pre-wired with external terminals.

Completing the trinity is the IWA-250 switch mode amplifier - a slim, powerful dedicated design in a heavy-duty 1U rack mount case. Delivering up to 250watts into 4 ohms, a single IWA-250 will power single or dual IWS-10s to provide higher power levels for larger rooms or to meet customer demands. The IWA-250 can be configured to switch on automatically using input signal sensing, or by using the preferred 12v trigger link from an AVR or system source. The IWA-250 will then automatically be switched on and off with the AVR, TV or system remote control handset.

The IWS-10 subwoofer driver employs a rigid, flat 10” surface of 10mm (3/8”) RDT® material derived from Monitor audio’s acclaimed ‘Platinum’ series of high-end speakers. A large vented pole helps to move air quickly, reducing power compression and increasing heat dissipation. Powered by the IWA-250 amplifier (available as an option and capable of driving two in wall subwoofers). IWB-10 back box also available.
