OverviewMonitor Audio IWS-10 In-Wall Subwoofer designed to add deep bass frequencies to architectural speaker Systems, Monitor Audio’s new in-wall subwoofer designs is an amalgam of sophisticated IWS-10 sub-woofer driver, SA-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 10” surface of 10mm (3/8”) 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 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 IWB10 will also reduce the radiation of sound to adjacent rooms. For easier installation, the IWB10 is pre-wired with external terminals.
Completing the trinity is the SA-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 SA-250 will power single or dual ISW-10s to provide higher power levels for larger rooms or to meet customer demands.
The SA-250 can be configured to switch on automatically using input signal sensing, or by using the preferred 12v trigger link from and AVR or system source. The SA-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.

Monitor Audio IWS-10 In-Wall Subwoofer Product review

Great SubI bought two of these subwoofers, one for a cinema room and one for music in my kitchen. Sub works great for both purposes and has plenty of punch!
You have to make sure you plan the install to get the best results with these, but this was relatively simple with the help provided by Rob and his team. The install itself was a breeze too.
