In-ceiling Speakers

Hidden Gems


In recent years, in-ceiling speakers have become a popular choice as they facilitate great audio experience without disrupting the visual aesthetics of the venue. In this guide, PALM Technology has covered some in-ceiling speakers launched in 2017-2018 with intent to provide readers with a quality guide that can help your sourcing needs.

Bose Edgemax


Bose Professional’s EdgeMax in-ceiling loudspeakers feature proprietary Bose PhaseGuide technology, which Bose says provides room-filling coverage while improving overall sound quality compared to the performance of conventional ceiling loudspeakers.

These in-ceiling premium loudspeakers are available with two different horizontal coverage patterns. EdgeMax EM90 models provide nominal 90-degree horizontal coverage and are intended for in-ceiling mounting near room corners.
