Description
Monitor Audio IV140 Invisible In-Wall Speaker
High-performance invisible in-wall or in-ceiling speaker designed to disappear completely once installed, plastered, and finished.
The IV140 is built for spaces where the design brief matters just as much as the sound system. Once installed and skimmed with plaster, it sits fully hidden behind the finished surface, with the option to paint or wallpaper over it so the speaker disappears into the room. That makes it a strong fit for clean architectural interiors, minimalist living spaces, and custom-install projects where visible speakers would compromise the look of the room.
Monitor Audio positions the IV140 as a concealed architectural speaker for projects where visible grilles are not wanted but proper in-room audio still matters.
Proper Architectural Audio Without Visible Speakers
A discreet solution for projects where the room design comes first
The IV140 is not a conventional in-wall speaker with a visible grille. It is part of Monitor Audio’s Specialist invisible range, designed specifically for concealed in-wall and in-ceiling use. That makes it particularly useful in high-end homes, multi-room audio zones, and design-led spaces where the client wants sound in the room without drawing attention to the speaker itself.
For the right project, that is the whole point. You keep the room visually clean while still adding a real installed speaker solution rather than relying on compromise products or surface-mounted alternatives.
Designed for Concealed In-Wall and In-Ceiling Use
Hidden once finished, but still built like a serious installed speaker
Monitor Audio states that the IV140 is suitable for both in-wall and in-ceiling applications, with overall dimensions of 642 x 401.5mm, a cut-out size of 591 x 350.5mm, and a mounting depth of 94mm. Construction uses 9mm MDF, with a black painted frame and white membrane ready for finishing once installed.
That makes it a product that needs to be planned properly rather than treated like a casual retrofit speaker. It is best suited to projects where the builder, plasterer, cabinetmaker, or AV installer can coordinate the install cleanly from the start.
Built for Discreet Background to Mid-Level Listening
Sensible output and installation-focused performance for architectural spaces
The IV140 uses one low-frequency transducer and two high-frequency transducers, with published sensitivity of 82dB, nominal impedance of 8 ohms, RMS power handling of 50 watts full range, and up to 100 watts music program when used with a minimum 80Hz high-pass filter. Monitor Audio quotes frequency response at 75Hz to 18kHz in a sealed cavity and 55Hz to 18kHz in open-back use, with maximum SPL of 102.8dBA.
In practical terms, that tells you the IV140 is designed for clean concealed architectural audio rather than brute-force output. It makes sense in rooms where discretion is the priority and the audio brief is more about quality distributed sound, TV support, or light music listening rather than trying to replace a large visible hi-fi speaker.
A Strong Fit for Custom Install Projects
Best used where planning, finish quality, and integration matter
Monitor Audio also lists sprung gold-plated push terminals, self-tapping screw fixing, and a dedicated pre-construction bracket, the WBIV140. It is sold as a single unit and backed by a 5-year warranty.
That is the sort of detail that matters on a real install. Products like this live or die on planning and execution, so the fact that Monitor Audio offers a matching bracket and clearly installation-led dimensions makes it a much more sensible option for proper architectural work.

The Audio Experts Take
The IV140 makes sense when the room design is driving the brief and visible speakers are not welcome. It is a specialist product for jobs where clean architectural integration matters more than showing off the hardware, and for the right project that can be exactly the right answer.
What we like here is that it gives you a genuinely discreet install option from a serious speaker brand, rather than a token hidden-audio product. The important part is using it in the right application and planning the install properly from the start. In the right wall or ceiling build, it is a very clever way to get sound into a room without cluttering the space visually.
