I have an original set of HK Soundsticks and iSub. The Soundsticks plug into the sub and the sub has an external power supply and plugs into a computer via USB. I would like to make this system connect to my MBP wirelessly. I see that there’s a Logitech adapter (https://www.logitech.com/en-us/product/bluetooth-audio-adapter?crid=1548 ) which could make the soundsticks reachable via Bluetooth, but this would not work for the sub because it only has USB. Any suggestions for device (other than another computer!) or instructions to hack the iSub?
