PLEASE NOTE: this subwoofer driver is passive and requires external amplification. It will not work directly with a home cinema amplifier/receiver.
The Monitor Audio IWS-10 In-Wall Subwoofer allows discreet placement of subwoofer for Home Cinema or Multi-Room installations. Providing excellent bass response the IWS-10 subwoofer driver utilises a super rigid flat 254mm driver manufactured from RDT material devised for Monitor Audio’s acclaimed ‘Platinum’ series of high-end speakers.
Designed to add deep bass frequencies to architectural speaker Systems, Monitor Audio’s new in-wall subwoofer design is a combination of sophisticated IWS-10 subwoofer driver, IWA-250 amplifier and IWB-10 back box. The system has been conceived to deliver optimum controlled bass in new walls or easy bass augmentation in retro-fit situations.
To provide excellent bass depth with maximum installation flexibility the IWS-10 subwoofer driver is a highly specialised design employing an extraordinarily rigid, flat 254mm surface of 10mm RDT material devised for Monitor audio’s acclaimed ‘Platinum’ series of high-end speakers. Rigid Diaphragm Technology is a sandwich of two layers 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 sufficiently well specified to generate excellent bass quality in a range of wall, ceiling, even floor locations, ideally but not exclusively with its IWB-10 back box, providing 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 returns 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 355.6mm 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 250 Watts into 4 ohms, a single IWA-250 will power single or dual ISW-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 amplifier utilises a cool running Class D power stage driven by a PWM with integrated DSP. All filtering and functionality are controlled in the software for precise and reliable operation. It offers a choice of single LFE, balanced XLR and stereo RCA inputs.
Output connection is made via two sets of push type terminals to provide connection to one or a pair of IWS-10 drivers. The front panel provides access to all control features for easy adjustment when fitted into a rack bay. An EQ switch provides a selection of music, movie and impact presets for the ideal response in-room. There is also an enclosure switch to calibrate the drive characteristics when the IWS-10 is used within or without the IWB-10 back box.
