These wireless Bluetooth ceiling speakers are the NCBT8B model from Power Dynamics, a high-quality pair of ceiling speakers that come in an active/passive design. The active/passive design means that there is one unit with a built-in amplifier that connects directly to a mains power socket using the included cable, while the second unit is passive and connects to the main unit using the supplied speaker cable. Rather than the standard white finish that the majority of ceiling speakers have, these active Bluetooth ceiling speakers have sleek black grilles that stand out in lighter-coloured ceilings for a unique look.
