Audibax CM508L-BT - Bluetooth Ceiling Speakers 2-way (13.3 cm) 2×20 W, Recessed Pair White

The Audibax CM508L-BT are a pair of in-ceiling Bluetooth speakers designed to easily provide sound in homes, businesses, and entertainment venues without the need for an external amplifier. The system integrates an active speaker (with amplification and Bluetooth receiver) and a passive speaker that connects to the first, delivering a combined 2 x 20 W RMS in stereo . Their 2-way design combines a 13.3 cm (5.25") 8 Ω woofer with a 13 mm (1/2") mylar tweeter for a clear frequency response of 100 Hz–20 kHz and a sound pressure level of 88 dB (1 W/1 m) . The ABS construction with a metal grille ensures a clean and discreet ceiling installation.

Power is supplied via a power adapter ( 220–240 V AC, 50/60 Hz input and 12 V DC output to the active speaker), and installation is quick: Ø 166 mm cutout, recommended depth 75 mm (body depth 68 mm), and a tab-based mounting system. Important: Due to Bluetooth protocol limitations, it is not possible to use two or more pairs of this model simultaneously in the same listening space.
