Providing unrivaled speech reproduction and voice intelligibility, with an outstanding speech transmission index of (.80), the SD5 offers a wide dispersion of high-frequency sounds, allowing listeners to clearly catch speech from a much wider proximity.

The frequency response needed to clearly hear a human voice is between 200 Hz and 7 kHz. Consonant sounds typically fall into a higher frequency band between 2 kHz and 7 kHz. 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.

Unlike conventional speakers that tend to have a very narrow high-frequency dispersion pattern, the SD5, through its proprietary design, has the ability to evenly disperse these critical frequency sounds, providing unprecedented crystal clear sound and speech reproduction to the listening audience.

Backed by more than 30 years of drop tile speaker research and development, the new SD5 is built with a proprietary high-frequency driver and frequency-matched low-frequency drivers  that extend the crossover point well below traditional ceiling speakers creating better audio coverage and response.

The proprietary tweeter technology works in perfect harmony with an array of custom-engineered drivers to reduce frequency cancellation and provide crystal clear sound. Strategically engineered waveguides shape the sound as it travels away from the speaker array eliminating any potential problem areas in the room. Additionally, the SD5’s reinforced wave-guide housing and directional vortex porting maximize audio dispersion and reduce turbulence within the speaker system. This cutting edge design offers 360 degrees of smooth, crisp clear audio coverage.

The SD5's spherical coverage pattern has a significant advantage over conventional ceiling speakers that produce a limited or conical (flashlight-light) shaped coverage pattern. Conical patterns can result in coverage voids or empty spots in between speakers. Less is more when reproducing vocals or amplifying music, it is always better with fewer speakers. When you have too many speakers creating the same sound, it can make it difficult for the listener to hear. This happens because they may experience the same sound from different speakers at different times causing audio confusion or listening fatigue.

The SD5 replaces multiple single speakers and provides an industry-leading 50' x 50' plus of audio coverage from a single array with zero frequency cancellation. This creates a more comfortable listening environment while also simplifying installation and dramatically lowering labor costs.

Building on more than 30 years of drop tile speaker research and development, the new SD5 omnidirectional drop tile ceiling speaker array is significantly improved in every area from the previous generation. Its sleek, thin, and lighter weight architecture paired with its seamlessly omnidirectional sound coverage, crisp vocal articulation, and low distortion makes the SD5 ceiling speaker array an outstanding high-end audio solution with beautiful aesthetics for any commercial space.

The SD5 is perfect for conference rooms, classrooms, training rooms, meeting rooms, lecture halls, auditoriums, control rooms, churches, offices and sound systems where hearing and clarity is critical.

Designed to install much quicker than a traditional ceiling speaker, the SD5 is built to save your most important currency, time. Simply remove one ceiling tile, drop the SD5 into any standard drop-ceiling grid, and attach your speaker wire. Secure the speaker from the four back suspension points using the provided carabiners and braided steel safety cable. Your sound system will be set up and operational quicker than ever before.
