The Pure Resonance Audio SD5 SuperDispersion omnidirectional drop tile ceiling speaker array claims a 360-degree coverage pattern with vocal articulation and low distortion. The SD5 provides 50’ by 50’ of audio coverage with zero frequency cancellation. According to Pure Resonance, strategically engineered waveguides shape the sound as it travels away from the speaker array, eliminating potential nodes. Additionally, the SD5’s reinforced housing and directional vortex porting maximize audio dispersion by reducing the speaker system’s turbulence.
The frequency response needed from a speaker to clearly hear human speech falls into a range that can vary depending on volume, pronunciation, tone and pitch. Unlike conventional speakers that tend to have a very narrow high-frequency dispersion pattern, the SD5, through its proprietary design, offers an unconventionally wide dispersion of high-frequency sounds allowing the speaker to have unprecedented vocal clarity. This makes the SD5 an option for classrooms, conference rooms, training rooms, auditoriums and meeting rooms of any kind.
