"While in-ceiling speakers may be high and above and mostly out of sight, the internal components can be the difference between immersive, rich sound for distributed audio and home theater versus standard background speakers. OSD Black Series in-ceiling speakers include the highest-grade components for optimal performance in a wide range of applications. Rigid polypropylene woofers for deep, rich bass and silk dome tweeters that fill in the critical high notes. OSD BLACK Performance Series in-ceiling speakers deliver extraordinary sound quality in a flush-mount design that stealthily blends into any décor. Our Performance series in-ceiling speakers include a unique blend of components such as graphite mineral-filled cone woofers that provide better dampening and added rigidity and control over bass and mid-range sound. Parachute silk soft-dome tweeters offer a precise but gentle sound to high notes such as stringed instruments, while contour switches allow you to tailor high-frequency settings to your exact taste. BLACK Performance in-ceiling speakers also include advanced crossovers networks that act as an audio traffic cop to direct frequencies to the right speakers, so you hear high, mid, and low range with emotion-evoking detail. Whether you are planning a whole house audio system or a full-blown home theater, you'll appreciate the sound and sleek appearance of OSD Black Series speakers, ensuring your audio experience is everything you expected and more.
