About the Monitor Audio IWS10 and WA250 In-Wall Subwoofer System

More bass, less space

I love the sound — and feel — of good, clean bass when I listen to music or watch a movie. But low-end punch comes with a tradeoff — most subwoofers take up space on your floor. This in-wall bass package from Monitor Audio offers the best of both worlds. You'll enjoy tight, clean bass without a bulky box occupying real estate in your room.

Monitor Audio IWS-10 in-wall subwoofer and WA250 amplifier

Enjoy deep, impactful bass with music and movies without taking up floor space.

The system includes an in-wall subwoofer and a matching 250-watt RMS amplifier. It's a great choice for a custom-installed home theater or stereo system in a small- to medium-sized room. 

Retro-fitting vs. new construction

If you're retro-fitting the IWS-10 into existing construction, this bundle may be a perfect choice. The subwoofer's patented Tri-Grip® clamping system makes it easy to get a good seal in sheetrock installations.

If you're installing the system in new construction, consider the package that includes the sub and amp, plus a matching in-wall enclosure, which helps you get the best possible sound.

Connecting your system together

You'll install the amplifier in your A/V cabinet, rack, or equipment shelf. It connects to your home theater receiver or preamp/processor via a subwoofer cable, and to the subwoofer via in-wall speaker wire.

If you ever want to expand your system, this amp can drive up to two IWS-10 subs (available individually) at the same time.

Features

In-Wall Passive Subwoofer: The Monitor Audio IWS-10 in-wall passive subwoofer features a flat 10" woofer which incorporates Ceramic-Coated Aluminum/Magnesium (C-CAM) and Rigid Diaphragm Technology (RDT). The result of combining these two technologies is low mass and greater strength that give the woofer 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 3.5625" profile. A large vented pole helps to move air quickly, reducing power compression and heat dissipation.

  • Ceramic-Coated Aluminum/Magnesium (C-CAM): 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, aluminum/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.
  • Rigid Diaphragm Technology (RDT): RDT is a unique technology developed specifically by Monitor Audio's engineers. Designed to reduce mass and increase cone stiffness, RDT applies ultra-thin skins of C-CAM to a core of honeycomb Nomex material, creating a structure which is extremely light but incredibly rigid. At only 40 microns thick, the C-CAM skins are half the thickness of a human hair, yet when bonded to the Nomex core they form an RDT cone, which is 150 times more rigid than a single layer of 200 micron C-CAM alloy, but has a fraction of the overall mass. These properties allow the cone to operate as a lightning-fast piston for a clearer more natural sound. The RDT cone's concave geometry has been refined by FEA analysis to provide a smooth frequency response and to eradicate break-up.
  • Trimless Grille: The IWS-10 in-wall sub features a "Trimless" steel-mesh grille that covers the entire speaker for a true trimless, stealth look. The IWS-10's trim-less grille and frame edge are paintable to blend discreetly with your room's decor.

Subwoofer Amplifier: The IWA-250 amplifier is specifically designed to power the IWS-10 passive subwoofer; the result is dynamic bass performance from an in-wall subwoofer. Delivering up to 250 watts into 4 ohms, the Monitor Audio IWA-250 power amplifier will power a single or dual IWS-10 in-wall passive subwoofers to provide higher power levels for larger rooms or to meet customer demands. The amplifier utilizes a cool running Class D power stage driven by a PWM supply with integrated DSP. Filtering and functionality are controlled in the software for precise and reliable operation.

Sub Controls: The Monitor Audio IWA-250 power amplifier offers the following sub control to tailor the system to your content, room, application, and preference.

  • Volume Control: This control allows the level or volume to be adjusted in order to achieve a balanced overall sound between the subwoofer amplifier system and your AV system.
  • Lowpass Crossover: The variable lowpass control (50-120Hz) only operates when using the RCA stereo inputs and is used to set the low pass frequency of the amplifier. The crossover control should be set in accordance with the size or bass output of your front speakers.
  • Phase Control: The Phase Control (0/180-degrees) is used to synchronize any delay between the subwoofer amplifier system and your main front speakers. When the subwoofer is in phase with your main speakers the sound should be full bodied.
  • EQ Switch: This switch tailors the bass response of the subwoofer amplifier system to your taste. There are three settings - Music, Movies and Impact. Movie mode provides a relatively flat response down to 35Hz. Music mode is -2dB down from Movie mode but goes lower, all the way down to 30Hz. Impact mode is +3dB up from Movie mode and comfortably goes down to 40Hz.
  • Enclosure Switch: There is also an enclosure switch to calibrate the drive characteristics when your IWS-10 passive subwoofer is used within or without the IWB-10 back box (sold separately).

Connectivity: The Monitor audio in-wall subwoofer and amplifier offer balanced & unbalanced inputs, along with spring-post input and output terminals.

  • Balanced & Unbalanced Inputs: The IWA-250 in-wall sub offers a choice of a single LFE (unbalanced RCA/balanced XLR) or stereo RCA inputs to connect the subwoofer amplifier to your AV receiver.
  • Spring-Post Speaker Terminals: The Monitor Audio in-wall sub and subwoofer amplifier are outfitted with spring-post terminals. The subwoofer amp features two pair of spring-post terminals to connect up to two IWS-10 passive subwoofers. The in-wall sub features one pair of spring-post terminals to connect to the sub amp. The spring-post terminals will accept bare wire (up to 10AWG), banana plugs (dual or single), and angled pin-connectors.

Mounting Options: The IWS-10 is specified to generate excellent bass quality from wall, ceiling, even floor locations, providing a wide range of new and retrofit possibilities ideally but not exclusively with its IWB-10 back box. The Monitor Audio IWA-250 power amplifier's slim design can fit in a1U rack-mount space. The front-panel allows access to all control features for easy adjustment when fitted into a rack bay

  • Tri-Grip Clamping System: The IWS-10 features Monitor Audio's patented Tri-Grip clamping system which is easier to install and provides 3x the surface area of a conventional dog-leg type clamp for better overall surface sealing. The four Tri-Grip fixings are made from a tough re-enforced polymer, giving a secure installation. The IWS-10 can only be fixed into drywall with a thickness of up to 1.5". Solid wall installation will require channeling out and frame work constructed to provide a structure for the Tri-Grip dog-legs to clamp to.
  • Optional Back Box (sold separately): You can also use Monitor Audio's IWB-10 in-wall back box (893IWB10, sold separately) to mount the IWS-10 in the wall. The IWB-10 in-wall box is designed specifically for the IWS-10 to provide easy installation and optimum performance. The IWB-10 is a sealed pre-construction back box, built from MDF and laminated with a rugged black Sandex vinyl finish. The IWB-10 is designed to fit between standard 14" stud spacing or 16" on-center.

Auto Power On/Off: The IWA-250 can be configured to switch on automatically using input signal sensing, or by using its 12V trigger (3.5mm) link from an AV receiver. The IWA-250 will then automatically be switched on and off with your AV system.
