8” Coaxial Ceiling Speaker

The Asystems CS series are high-fidelity in-ceiling speakers that offer versatile operation in commercial and private application. With driver sizes ranging from 5½” to 8″ – with coaxially mounted tweeters in most cases – and incredibly diverse power handling and sound pressure levels, the CS series consists of four premium, lightweight speakers that can be easily installed in even the most demanding of venues. With 25 to 40 Watt power handling, these discrete speakers are ideal for moderate to high ceiling installations such as those found in schools, gymnasiums, meeting rooms, shopping centers and retail outlets. The versatile operating modes (8 ohms, 70V and 100V) make them ideal for almost any installation. The dual-coil CS-8SUB matches perfectly with any of the coaxial models, adding a little extra bass to your music. Ideal for background audio systems and talk-over systems, the CS series can be integrated into almost any ceiling material.
