Ubiquiti UACC-IN-CEILING-SPEAKER UniFi 6.5 inch passive in-ceiling speaker, 130 W, 8 ohm
The UACC-In-Ceiling-Speaker is a passive 6.5" two-way speaker designed to be installed flush in a ceiling. It combines a 6.5" woofer with an adjustable 1" tweeter, covering roughly 47 Hz to 20 kHz with 90 degree axisymmetric dispersion. Power handling is up to 130 W at 8 ohms, and it connects using standard 8 to 16 AWG speaker wire. A magnetic grille can be removed quickly to access the speaker, and screw clamps hold it in place in suspended or grid ceilings. Like the in-wall model, it needs an external amplifier such as the UniFi PowerAmp. It is well suited to offices, retail spaces, hospitality venues and homes.
