I have an M1 Mac Mini that I recently set up as a utility computer in a downstairs room. My wife likes to listen to music while working (not working on the computer, she's an artist) and my idea was to use a JBL Flip bluetooth speaker that she could easily move around. However, the speaker would only work within maybe 15 feet of the computer at best, maybe less. Those speakers work with phones over much greater distances.
There's this question that suggests an extender; is there anything else I can try that doesn't involve additional hardware?
