Monitor Audio Platinum In-Wall II: Reference In-Wall Loudspeaker for Home Cinema
The Platinum In-Wall II is Monitor Audio’s flagship in-wall loudspeaker, purpose-built for custom high-end home cinema installations where dynamics, scale, and natural sound reproduction are paramount. Its three-way, four-driver architecture delivers a wide, coherent, and highly precise soundstage — comparable to that of the brand’s finest floorstanding speakers — while maintaining a discreet in-wall integration.
Thanks to its flexible vertical or horizontal installation, the Platinum In-Wall II is ideal for use as LCR channels in multichannel systems, ensuring perfect tonal consistency across the front soundstage.
The driver configuration includes dual 6.5" RDT II woofers, a 4" RDT II midrange driver, and a MPD (Micro Pleated Diaphragm) high-frequency transducer, specifically engineered for the Platinum II series. Exclusive innovations such as DCF (Dynamic Coupling Filter) technology and high-efficiency underhung flat-wound voice coils guarantee exceptional dynamics, reduced distortion, and natural musicality.
A sealed 25 mm MDF enclosure with steel back plate and internal bracing ensures maximum rigidity, eliminating unwanted resonances while enhancing low-frequency control. Combining engineering excellence, timeless design, and discreet installation, the Platinum In-Wall II represents the pinnacle of British architectural audio.
