Up close. Here's the speaker unit.Subtle mount on the bluetooth speaker. Didn't even notice it. Looking forward to your 'exhaust'...
Here it is tucked in, set screw tightens against a rubber band similar to a rubber bracklet, set in the middle of the speaker. (happy accident, I didn't know it was there when I ordered the speaker) Set screw will be a nylon 1/4-20 knurled edge if I can find one.
now to get the other side goin'...
