What customers say
Customers consistently praise the Monitor Audio Platinum In-Wall II speakers for achieving true high fidelity within an architectural format. The core admiration focuses on sonic performance, specifically the clarity delivered by the high-frequency transducer, which reviewers find airy and detailed without fatigue. Mid-range and bass response are noted as fast and articulate, offering surprising impact for an in-wall design. Build quality is described as meticulous and robust, justifying the premium investment for those prioritizing aesthetics and uncompromising audio. The consensus is that these speakers successfully bridge the gap between invisible installation and reference level sound, making them a top choice for discerning listeners.
Know before you buy
Yes. The mid/high frequency driver array can be rotated 90 degrees, allowing you to maintain precise audio imaging and consistent sound dispersion whether the speaker is mounted vertically or horizontally.
With a nominal impedance of 4 ohms and a power handling range of 100 to 200 watts RMS, you should pair this with a high-quality, stable amplifier capable of driving 4-ohm loads effectively to ensure the best dynamics and control.
The Platinum In-Wall II is engineered to provide the same tonal integrity and lifelike scale as Monitor Audio's flagship boxed systems. By utilizing RDT II driver technology and an MPD high-frequency transducer, it delivers reference-grade audio fidelity while remaining discreetly tucked into your wall.
The speaker features a frequency response of 52 Hz to 100 kHz. While it provides excellent clarity and detail, you may want to pair it with a dedicated subwoofer if your home theater setup requires deep, low-frequency impact below 52 Hz.
The speaker measures approximately 47.5 inches tall and 13 inches wide, with a depth of about 4 inches. Given its weight of 59.5 lbs, ensure your wall structure is reinforced and capable of supporting the load before installation.
A three-way design uses separate drivers to handle specific frequency ranges—bass, midrange, and high frequencies—rather than forcing one driver to do everything. This results in cleaner, more accurate sound reproduction with less distortion, especially during complex cinematic sequences.
