For years the CRS6 has been the most popular series in SpeakerCraft's entire line. Delivering amazing sound quality in a compact, flush-mounted enclosure, these speakers began the move into ceiling installations that changed the entire industry. 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. First of all, the tweeter pivots to allow you to aim the critical high frequencies at the listening area. SpeakerCraft also created the WavePlane® which, supports the tweeter and keeps those same high frequencies from bouncing off the woofer. This means better sound and more uniform coverage throughout the room.
