Welcome to our OSD Audio S82-MK2 On-Wall LCR Home Theatre Speaker Review where we dive deep into the impressive performance of this on-wall marvel. If you’re seeking theatre-grade sound without the bulk of a tower speaker, the S82-MK2 is engineered to meet and exceed Dolby and THX reference levels, delivering an immersive audio experience with a sleek 6.2" depth that blends seamlessly into any home cinema setup.

Design and Build Quality

The S82-MK2 is part of OSD Black’s premium S Series, featuring a front-inverted wood cabinet and high-transparency grille that virtually disappears once you press play. At just 6.2" deep, its sonically-neutral enclosure is designed for stability and resonance control, ensuring the cabinet vanishes when the action starts. Gold-plated speaker terminals promise pristine signal transfer, and the slim profile allows for flexible placement—flank your screen or mount beneath for seamless integration.

Acoustic Performance

At the heart of the S82-MK2 lies a unique triple silk dome tweeter array capable of achieving a maximum peak of 116dB—well above the Dolby and THX reference SPL of 105dB—without a hint of distortion. The rotatable faceplate lets you orient the tweeter array vertically or horizontally, allowing perfect high-frequency timbre matching to your room’s acoustics. Complementing the highs is an 8" long wood fibre cone woofer with a low-carbon steel magnet, delivering tight, powerful bass with minimal cone resonance even at high volume levels.

Technical Highlights

• Custom-designed crossover network with German polypropylene capacitors and Japanese silver solder for precise frequency routing.
• Parallel and series wiring in the crossover stage for accurate separation of highs, mids and lows.
• Triangular silent spider and pure copper edge-wound voice coil for improved power handling and heat dissipation.
• Gold-plated binding posts ensure optimal connectivity.

Who Should Consider the S82-MK2?

If you’re an audiophile who needs uncompromised surround sound but lacks the space for large floor-standers, the S82-MK2 is tailor-made for your setup. Home theatre purists will appreciate the speaker’s ability to hit reference levels with surgical precision, while those on a tighter budget will marvel at the value proposition—premium components and performance usually reserved for speakers at twice the price.
