The CI Home series address the important considerations when selecting custom installation speakers: truly superior sound, easy installation, and a new bezel-free micro-perf grille with an incredibly discreet aesthetic. Without any unnecessary pressure or force, each turn of the screwdriver turns the clamp. We show the starting point, we show the screwdriver working to turn the clamp, and finally, we show the speaker locked into place inside the wall or ceiling. It doesn't get simpler or easier! Our High-Strength ABS Chassis and Clamp System addresses the flexibility problem that plagues all walls and ceilings. ABS stiffness combats unwanted resonances and vibrations and equally important, the new clamp design makes the installer's job easier and faster!
