The CIS300 is a compact two-way flush-mount loudspeaker assembly designed for fixed installations into typical ceiling plenum spaces. Employing a modified HF waveguide originally developed for use in studio monitors, the CIS300 delivers superior dispersion and pattern control over conventional coaxial designs. The waveguide integrates the HF driver with a 4″ LF driver optimized for smooth frequency response and seamless transition through the crossover point. The result is acoustic performance not generally associated with a commercial ceiling speaker of this size or in this price range.
