Monitor-quality sound in the ceiling. That's why we call the new CIS400 a ceiling monitor. Wide frequency response, combined with controlled dispersion give the CIS400 many of the same characteristics as a quality studio monitor speaker. By using technology employed in our industry standard Mackie HR Active Monitors, we have developed a ceiling-mounted speaker that delivers performance that is more comparable to a studio monitor than a typical ceiling speaker.

Wider dispersion means a larger "sweet spot." Lots of speakers sound good when you're seated directly below, but the sound changes dramatically as you move off-axis.  The CIS400 employs a unique high-frequency waveguide, originally developed for our studio monitors, that extends coverage to 110° at 8kHz.  The result is noticeably better sound throughout a larger area of coverage.

Extremely versatile. The CIS400 features a true 2-way crossover for linear phase response and accurate reproduction.

The end result: Better response, greater intelligibility and wider coverage across all
