I have a Denon stereo system which wires through to speakers. I would like to purchase speakers (preferably ceiling speakers) that also has Bluetooth capability so that I can connect to my iPad and iPhone?
There are no in ceiling bluetooth speakers since they would require ac to power them. Much more complicated to wire.
If you want the in ceiling speakers to operate independently of the Denon then the best option is to use a Sonos ConnectAmp to power them and access streaming services and local file playback.
A less expensive option is to connect them to an amp that has bluetooth as an input. https/www.amazon.com/Bluetooth-Audio-Receiver-Amplifier-Model/dp/B00JB4YWGO
