I have the same problem here, with a bose sound. I use it together with my iMac speakers, because it has better bass sound and both in same time create better audio experience.
But the latency in bluetooth transmission is ruining this possibility of sound, it sucks. If you had a latency regulator, you could adjust it. But there is no way to do that, it is necessary for Apple to correct it earlier as possible.
Hello gcosmico and welcome to Apple Support Communities.
It appears you have a concern about latency between audio you play via the speakers of your Mac and a Bluetooth audio device.
Some latency, just based on basic physics, is expected as 1) Radio waves used by Bluetooth move at a fraction of the speed of electricity flowing through the Mac so latency will increase as the audio device (receiver) moves further from the Mac (transmitter). 2) There is an extra digital to analog conversion in the Bluetooth audio device which adds some latency.
At this time, the only combo of Apple products that sports the kind of time alignment feature you are referring to is HomePod when it is used as the output for an Apple TV device.
If you would like to leave feedback for Apple about that, you can do so here: Feedback - macOS - Apple Using the drop-down menu on that page, choose the option for Feature Request. Cheers.
