Big dynamics for a theater that deserves big sound
The Audience 212 was designed for home theaters where effortless output, clarity, and scale matter more than keeping the speaker small. With two 12-inch SB Audience Nero woofers flanking a horn-loaded compression driver, this design has the cone area and sensitivity needed to reproduce movie soundtracks with authority.
The symmetrical driver arrangement places the high-frequency horn between the two woofers, helping create a strong, focused front stage while giving the system enough output capability for large rooms and demanding listening levels.
At the center of the design is the SB Audience Rosso compression driver paired with the H250 horn. Combined with the dual Nero woofers, the Audience 212 is built to reproduce everything from quiet dialogue to large dynamic effects without sounding strained when the soundtrack gets aggressive.
