The Pure Resonance Audio SD5 SuperDispersion omnidirectional drop tile ceiling speaker array is the premium solution for speech reproduction and intelligibility that maximizes audio coverage.
UNRIVALED SPEECH REPRODUCTION
In order for listeners to clearly hear what is being communicated through a speaker, the speaker must be able to spread a wide range of high-frequency sounds across a room. The SD5, through its proprietary design, has the ability to evenly disperse critical frequency sounds, providing unprecedented crystal clear sound and speech reproduction to the listening audience.
THE BEST COVERAGE
Backed by more than 30 years of drop tile speaker research and development, the SD5 creates a smooth, even 360-degree audio coverage pattern and better speech reproduction than any ceiling speaker on the market today.
TOP PERFORMANCE FROM MINIMAL SPEAKERS
Just one SD5 speaker takes the place of multiple traditional single ceiling speakers and provides an industry-leading 50' x 50' plus of audio coverage from a single array with zero frequency cancellation.
VERSATILE COMMERCIAL SPEAKER SOLUTION

The SD5's cutting edge technology and clear sound make it ideal for many audio sources including professional AV equipment, conferencing hardware, microphones, media players, and personal audio devices. It is an outstanding high-end audio solution perfect for conference rooms, classrooms, training rooms, meeting rooms, lecture halls, auditoriums, control rooms, churches, and office sound systems.
QUICK AND EASY TO INSTALL
Designed to install much quicker than a traditional ceiling speaker - simply remove one ceiling tile, drop the SD5 into any standard drop-ceiling grid, attach your speaker wire and safety cables, and you're done.
