The Pure Resonance Audio SD4 SuperDispersion® omnidirectional drop tile ceiling speaker array takes speaker performance to a new level by providing 360° of powerful hemispheric audio coverage. A single SD4 speaker provides 30' x 30' of audio coverage depending on the application. Its high-performance sound and operational versatility make it an ideal solution for music, announcements, and paging. Each SD4 array can replace multiple conventional ceiling mounted speakers, simplifying and reducing installation time and cost while optimizing performance. The SD4 is extremely quick and easy to install - simply remove one ceiling tile, drop the speaker into any standard 2x2 or 2x4 drop-ceiling grid, attach your wire and safety cables, and you're done in just minutes.

Ideal for drop tile ceilings and featuring a stylish, intelligent design, the Pure Resonance Audio C3 3" micro ceiling speaker is compact and lightweight. This ceiling speaker seamlessly blends into the ceiling creating a beautiful architectural look. With 8 ohm and 70 volt taps, the C3 ceiling speaker is designed to provide excellent sound quality for a wide variety of low to medium volume applications such as background music, paging and ambient sound masking in commercial environments. An ultra-thin flat bezel allows the C3 to blend into ceiling planes. The quick and Easy-Mounting threaded ring provides secure, clean installation onto ceiling tiles and many other ceiling types.
