The NEAR ORBIT Pendant Speakers are perfect for the Carlisle Expo Center because ceiling heights vary from 12 to 18 feet throughout the facility. To achieve even, balanced sound, the speakers were hung 12 feet apart and 12 feet from the floor throughout the hall. By limiting the distance from floor to speakers to 12 feet, the event attendees can hear better while the demand for maximum speaker volume is minimized. “We selected the Bogen speakers and amplifiers because they blend well together and it’s a flexible system that integrates music and telephone paging,” said Knight. Speakers are tapped to 4 watts, according to Flannery.
Sound quality remains consistently high throughout the Center because the NEAR ORBIT pendant speakers were specially designed to provide exceptional bass in free space without the bass reinforcement speakers get when mounted in ceiling or corners of rooms. The stable, high-definition, metal-alloy woofer cone and polycarbonate tweeter provide 140-degree wide dispersion for broad, even coverage and contribute to their crisp sound quality. In addition, the 6-1/2 inch metal-alloy cone delivers highly detailed sound.
The NEAR ORBIT Pendant Speakers (available in black and white) use a patented magnetic liquid suspension (MLS) technology to precisely center the voice coil in the magnet gap. This eliminates the need for voice coil spiders found in conventional speakers and allows for longer speaker excursion. Since voice coil spiders can cause distortion, it’s an improvement to remove them. Thanks to MLS technology, as the audio becomes louder centering becomes more accurate. The metal cone and MLS also improve heat dissipation from the voice coil, which increases power handling and reliability.
Eleven Bogen Easy Install® Surface-Mount Ceiling Speakers (SM1EZ) were installed in the office area, and they are powered by a Bogen Telephone Paging Amplifier (TPU15A) as a separate zone. For exterior emergency pages, a Self-Amplified Horn Speaker (SAH15) was installed as a separate zone, and is powered by the Multi-Zone Telephone Interface (UTI312) which has a 1A, 24V DC, built-in power supply.
The Self-Amplified Horn Loudspeaker (SAH15) located on the Center exterior provides extended low frequency response from a 1.6-inch diameter voice coil and 3.54-inch, 12-ounce magnet. Also, the horn’s flare shape results in a controlled sound dispersion over the full frequency range for maximum intelligibility. To ensure long life and trouble-free service, the speaker features a weatherproof, UV-protected plastic housing.
