Pure Resonance Audio SD4 SuperDispersion Drop Tile Ceiling Speaker Array
with Built-In 8 Ohm/70V TransformerAfter 25 years of unparalleled success in the omnidirectional ceiling speaker marketplace, we have taken that experience and designed the ultimate commercial in-ceiling speaker technology. The SD4 takes ceiling speaker performance to a new level. For over 25 years, audio professionals worldwide have chosen the SuperDispersion™ (SD) Ceiling Tile Speakers for their powerful sound, high performance, and distinctive styling. The SD4 is an innovative speaker concept that meets the demanding needs of audio and system contractors worldwide.
The SD Speakers' pyramid design fits into standard 2'x2' or 2'x4' ceiling tile grids, providing an amazing 360 degrees of hemispheric sound. SD speakers are quick and economical to install and are competitively priced, making them an excellent value to contractors! SD4 ceiling speaker array systems offer performance, value and are ideal for classrooms, office sound systems, conference rooms, teleconferencing, churches, retail stores, restaurants, schools, universities and sound masking systems. Takes minutes to install, just remove one ceiling title and drop the SD4 into any standard 2x2 or 2x4 drop ceiling. The 8 ohm and 70 volt inputs are compatible with any commercial or stereo sound system.
About The SD4 Speaker Technology
The SD Speaker employs (4 smaller 6.5") very fast transient response aluminum-woofer drivers that are very powerful and stable. Working in unison these drivers produce clean powerful dynamic sound. When designing the SD the goal was to have the single most import feature at the forefront, good transient response ("dynamic contrast"). A transient is a sound of short duration, and good transient response can only be achieved if the speaker can deliver its output quickly and cleanly without smearing the original sound, and be completely soundless immediately after. Transients contain the essentials of sound reproduction they provide the sharp pop from a snare drum, the cutting edge of digital sound, the dynamics of the human voice. Larger 2-way cabinet loudspeaker systems offer a relatively slow transient response, and the small high-frequency horn tends to beam a narrow, blaring sound at the listener—end result, muddy sound. By replacing larger speakers with four 6 or 8" drivers we increased the driver surface area while creating more punch and a tight, more focused low-end.
