Next-Generation Performance: S81-MK2 Speaker

Part of OSD Black's premium S Series of ultra-high-performance home theater speakers, the S81-MK2 speaker represents the next generation that improves on an already superb design. Let's highlight the standout features that make this remarkable speaker truly exceptional.

Three Tweeters for Ultimate Sound

The S81-MK2 features three dome tweeters instead of the typical one. This triple tweeter array allows for significantly higher SPL levels and less restricted sound. To exceed Dolby and THX SPL reference levels of 105dB and achieve clean, non-distorted sound with a peak of 116dB, the S-81 MKII is rated at an impressive 112dB. The triple tweeter array can be rotated on a faceplate, enabling vertical or horizontal orientation. This ensures perfect high-frequency timbre matching and lets audiophiles optimize performance based on their room's acoustics.

Long Wood Fiber Cone Woofer with Low-carbon Steel Magnet

Don't overlook the S81-MK2's 8" wood fiber cone woofer. Crafted from long wood fiber material, it reduces cone resonance for reduced distortion. Given the high SPL capabilities of this speaker, maintaining minimal distortion is crucial. A rigid cone woofer ensures accurate pistonic air displacement and lower distortion. The magnet structure has been enhanced, utilizing a larger low-carbon steel magnet and a triangular silent spider attaching to the pure copper edge-wound voice coil.

Advanced Crossover Design

Complementing OSD Black's triple tweeter array is an advanced crossover design. Revised crossovers utilize parallel and series wiring for precise frequency response. The crossovers incorporate higher-quality air-core choke resistors and polypropylene capacitors to create a foundation that routes frequencies with orchestral precision. This synergy with the triple tweeter array ensures an impeccably separated sonic highway for high, low, and medium frequencies.

Sonically-Neutral Cabinet

Each speaker in the Black S series features a sonically-neutral cabinet, providing a stable, resonance-free platform for custom drivers. This design virtually makes the cabinet "disappear" during music or movie playback, delivering a precise soundstage, controlled bass, natural mids and highs, and an emotionally impactful audio experience.
