The CS801FL 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. The FastLoc™ grill is a patent pending feature found only at Current Audio. Our design has allowed for the smallest exposed plastic bezel in the industry, truly making it disappear into the mounting surface. The FastLoc™ grill's unique patent pending mechanism allows for a quick installation and removal of the grill while securely fastening it in place to all types of mounting surfaces. Due to the unique design the grill will conform to uneven surfaces including popcorn, heavy textured and uneven ceilings. While our competitors have chosen to utilize magnets in their designs thus requiring the use of a steel grill that will rust our design allows us to use corrosion and rust resistant aluminum. This revolutionary combination provides superior and more natural sound for both foreground and background applications. In addition the CS801FL 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.
