The CRS8 Zero delivers amazing sound quality in a flush-mounted application. More and more speakers are moving into ceiling installations. Because we rarely notice the vents, lights, sprinklers or anything else over our heads, putting the speaker in the ceiling was only natural. These speakers also offer technology that makes them unique in the way they disperse music or movie soundtracks in the room. The tweeter pivots to allow you to aim the critical high frequencies at the listening area. This means better sound and more uniform coverage throughout the room.
