Quam SYSTEM 21 Indoor Ceiling Mountable Speaker, 20W RMS, White

Deliver dependable, intelligible audio where it matters most: the Quam SYSTEM 21 indoor ceiling mountable speaker is a pro-grade solution for commercial paging, security and surveillance monitoring. Built by Quam Speakers, this ceiling speaker combines a rugged 8" driver, 20W RMS power handling and a sensitivity of 92 dB to produce clear voice announcements and balanced background music that cut through ambient noise.

The included steel baffle and backbox simplify hard-ceiling installation and protect components, while compatibility with 70V/25V distributed systems makes it straightforward to scale across multi-zone installations.
