The Sonodyne IWO 821 made of  bass-reflex on-wall/in-wall centre is capable of being the perfect addition to your home theatre experience with a richer and more natural dialogue reproduction. The 1″ dome tweeter gives the highs sharp and natural and vocals crystal clear, the 3″ woofers come with passive radiators to provide balanced and controlled output, and the design is dual to deliver consistency and high-quality sound across the board. It has a frequency response of 75Hz 20kHz, 82dB sensitivity and 8 impedance, which is compatible with 60100W-rated amplifiers. With a 3.2kHz crossover, it provides clear extended sound in a thin satin black MDF case with a wide range of wall-mounting.
