Redesigned from the ground up, the CS-1900 ceiling speakers are loaded with quality components resulting in clean, powerful sound. They use the ceiling void as an infinite baffle – allowing un-restricted driver excursion – all of which adds up more bass. Low impedance speakers like these offer better sound that 100/70v line speakers. Perfect for meeting spaces.- The simple attenuation switch on the front allows the user to fine-tune the EQ for the environment- The large tweeter is made from premium material and pivots to help installers setup the soundscape- Kevlar gives smooth audio with incredible detail and transparency- The grill clips into place magnetically once the speakers are secured- The grill extends all the way to the edge of the speaker resulting in virtually no visible edge- A cutout template is included so the installer can easily trace the cut line in the ceiling tile- Only 87 mm (3.4″) deep, the CS-1900 can be placed anywhere around the room to optimally disperse the sound- Gold plated terminals and a quality crossover circuit is included which splits the work between the woofer and tweeter- Ceiling speakers often lack the power of wall speakers, but these have a higher sensitivity of 90dB to cut through high-noise presentation environments- The clamps are an extra long 35 mm (1.4″) to cope with ceilings made of very thick material
