S81 MK2 Speaker (PZA)
8” Fiber Cone Woofer Triple Tweeter Array Home Theater In-Wall Speaker, Custom S81 MK2 Crossovers
Part of OSD Black's premium S Series of ultra-high-performance home theater speakers, the S81-MK2 speaker is the next generation improvement on an already excellent design. It could take us days to break down the performance level of this remarkable speaker, but we'll highlight the most important features that will make listeners sit back and say 'wow.'
Three tweeters for Ultimate Sound
Our S81-MK2 features three dome tweeters instead of the typical one. The triple tweeter array allows for much higher SPL levels and a less restricted sound. Our audio engineers wanted to meet and exceed Dolby and THX SPL reference levels of 105 dB and achieve clean, distortion-free sound at a maximum peak of 116 dB. The S-81 MKII has a nominal power of 112dB. The triple tweeter array sits on a rotating faceplate, allowing the tweeters to be oriented vertically or horizontally. This ensures a perfect blend of high-frequency timbres and allows audiophiles to choose which orientation works best with the acoustic characteristics of their room.
Long wood fiber cone woofer with low carbon steel magnet
Let’s not overlook the S81-MK2’s 8” wood fiber cone woofer. The long wood fiber material is thicker, which reduces cone resonance because resonance causes unwanted distortion. Remember that this speaker generates high SPLs which can cause distortion. A rigid cone woofer ensures piston-like air displacement and lower distortion. We also improved the magnet structure of this next-generation speaker, which now utilizes a larger low-carbon steel magnet and a quiet triangular spider that attaches to the pure copper edge-wound voice coil.
