Monitor Audio Invisible IV140 Review: The Ultimate Invisible Hi-Fi Speaker
Monitor Audio Invisible IV140 Review

Welcome to our Monitor Audio Invisible IV140 Review, where we delve into the realm of concealed high-performance audio. This in-wall marvel from Monitor Audio disappears behind your decor yet commands the room with detailed, powerful sound. Perfect for audiophiles seeking pristine performance without visible speakers, the IV140 is our pick for seamless integration and uncompromising fidelity.
Sleek Concealment Meets Superior Engineering
The Invisible IV140 is designed to nestle into any standard 4 inch stud bay and vanish under a skim of plaster or fabric wallpaper. Once installed, it is completely hidden yet fully loaded with advanced technology. A rigid MDF back box isolates the speaker chamber, controlling resonance and eliminating rear sound leakage. That means precise imaging and a focused soundstage without disturbing adjacent rooms.
Unpacking the Tech
Under the grille, a large low-frequency transducer powered by high-power ceramic magnetics delivers deep, authoritative bass down to 55 Hz. Dual high-frequency transducers with potent Neo magnets and 30 mm voice coils extend the response to 18 kHz, offering crystalline highs and complex midrange textures. The two-way crossover network ensures seamless blending, preserving coherence across the spectrum and preventing driver overlap.
Overload protection is built in via automatic re-setting circuit breakers, so you can push the IV140 without worry. With a nominal impedance of 8 ohms, a sensitivity of 82 dB and a maximum SPL of 102.8 dBA, it pairs effortlessly with a wide range of amplifiers rated from 20 to 100 watts.
Sound Performance: Bass Authority and Clarity
In home cinema settings, the IV140 transforms dialogue with razor-sharp precision and delivers film scores with authoritative weight. In music playback, it excels at revealing subtle harmonic details and offers a warm yet articulate bass foundation. The controlled dispersion pattern provides a wide sweet spot, making it ideal for both focused listening seats and open-plan areas.

Installation and Integration
Whether you are building a dedicated home theatre or a distributed audio system, the IV140 fits the bill. The self-tapping screws and sprung push-type gold-plated terminals simplify wiring, while the pre-construction bracket WBIV140 provides a secure framework if you are planning ahead. After plastering, paint or light wallpaper finalises a professional finish.
Who Should Consider the IV140
The Invisible IV140 is perfect for:
- Home cinema enthusiasts who demand high SPL and tight bass
- Interior designers and architects seeking clean, uncluttered walls
- Hospitality venues and retail spaces where aesthetics and sound quality are equally vital
