The goal here is to reproduce the sound of a concert hall or the sound of a movie sound track in any room with ceiling mounted speakers. IQ speakers deliver deep, natural bass from the design of their advanced cone and surround. Superb sonic accuracy is guaranteed by the utilization of glass fiber in the woofer and silk in the tweeters. Additionally, you can customize the sound of the speakers with mid and tweet adjustment switches that optimize the sound to the acoustics of the room and an end user’s own personal preference.
