The CS501 is a full-range ceiling loudspeaker that incorporates an Injection Molded Graphite woofer with a butyl rubber surround and Ferrofluid cooled titanium coated polycarbonate tweeter. The tweeter allows for deeper penetration into the room and concentrated sound to the sweet spot. This revolutionary combination provides superior and more natural sound for both foreground and background applications. The Infinite Baffle design makes it the ideal choice for typical applications in open beam attic or enclosed ceilings.
