The CBR Series is a line of passive loudspeakers developed by adopting the extensive knowledge of speaker designand acoustic technologies that Yamaha has accrued over a long and storied history of making speakers of every kind. Combining a meticulous materials selection process, thorough customization of the audio components, and a fresh, innovativeapproach to speaker design, our engineering team's primary focus was to deliver high-power, high-definition sound in a highlyportable and versatile design that is equally at home in front-of-house, floor monitoring, or rigged configurations. The CBR15 provides the lowest frequency in its lineup, delivering outstanding performance for the front-of-house sound for live performance, DJ events or for installation situations that require highly prominent low and high SPL.
