The CI-IW55 is a premium grade in-wall speaker system designed to optimize multi-channel installations. Proprietary cast frame carbon/wool Quiet Cone™ woofers, and a 1” neodymium silk dome tweeter, provide outstanding performance with superior dynamics and power bandwidth. Dialogue intelligibility, precise tonality and power handling are better than any standard in-wall speaker in this price range. A rugged 3/4” wide aluminum mounting frame is fastened to a 3/4” thick MDF baffle with integral back box. This back box serves as an acoustic back wave isolator, as well as the proper tuning mechanism for the dual 5.5″ woofers. A minimum phase HQ crossover, with polypropylene capacitors and air core inductors, optimizes frequency response and minimizes distortion. The CI-IW55 can be used as an LCR, as well as a directional surround in high-end ATMOS configurations.
