CS801 is a full-range ceiling loudspeaker that incorporates an injection molded carbon fiber woofer with a butyl rubber surround and diffraction-less aluminum dome Ferrofluid cooled tweeter. This patent pending pivoting tweeter allows for deeper penetration into the room and a concentrated sound to the sweet spot. This revolutionary combination provides superior and more natural sound for both foreground and background applications. In addition the CS80 incorporates a 3-position equalization switch, one each for bass and treble to fine-tune the acoustics and allow for various room surfaces. The Infinite Baffle design makes it the ideal choice for typical application in open beam attic or enclosed ceilings.
