Our Black S Series on-wall bookshelf speakers are all about performance and are the perfect addition to high-end, dedicated home theaters. This beautifully crafted series includes three 2-way speakers (S81, S82 & S84) and one 3-way speaker (S85), all four of which are tailored for audiophiles who appreciate the subtle but significant differences between high-end and ultra-high-end speakers. All speakers in the Black S series have a sonically neutral cabinet design for a stable, resonance-free platform for the custom drivers. The cabinet virtually “disappears” when the music or movie begins so all you hear is a precise soundstage, deep and controlled bass, crisp and natural mid and high frequencies.
