Tech Gallery: Ceiling Speakers
Ceiling speakers, flush-mounted and pendant, remain the most reliable and least intrusive way to distribute sound by wire rather than relying on high output acoustic power from a few large units to fill a space. A properly adjusted ceiling speaker system can also provide more gain before feedback for live microphones used in the same environment. With the wide range of coverage and powering options available now, an installation plan requires careful and detailed planning.
