I thought so too, but then, I could never manage it myself. I imagine a solution would be to build a receiver with a Bluetooth antenna for each channel, so that it would be device-agnostic, and a mic port for calibration. Maybe a traditional RCA port for a powered subwoofer. But if it were so simple, I'm sure someone would have done it by now. There may also be weird licensing issues involved, like perhaps Dolby/DTS don't want to certify such a system, and so access to whatever you need to decode their signals isn't readily available.

I'm not sure you'd even need separate Bluetooth chips/antennas. In theory one device can connect to up to 7 others. Although, to be fair Bluetooth audio streaming is barely reliable with one device so maybe that is just asking too much of it. Apparently Samsung phones can connect to two devices: https://www.lifewire.com/how-to-connect-multiple-bluetooth-speakers-4173788 https://www.lifewire.com/how-to-connect-multiple-bluetooth-s...

  I think Bluetooth is just getting there now, so we will probably see more of this going forward. https://www.bluetooth.com/learn-about-bluetooth/bluetooth-technology/le-audio/ https://www.bluetooth.com/learn-about-bluetooth/bluetooth-te...

    That's Low Energy Bluetooth though, a totally different thing. You can't do audio through BLE at all before this.

  Yes, dual output is possible (there are receivers that do this today). However, BT4.2's low bandwidth limits the bitrate of sound that can be streamed, and I'm unclear on if each connection can receive different channels (basically, separate streams for each speaker), if it's limited to two identical stereo streams. I am a layman, though; I just sold the stuff and therefore had an understanding of what people expected to be possible.
