Amplified speaker 5-watt GE 1 9 D 4 3 2 3 1 5 G
This has a potentiometer w/ small screwdriver slot on left side of rear housing. It is an adjustment. Without the printed instructions, I don't know what I am adjusting.
I know I can simply hook it up and try. Just an attempt to check first.
Thanks and take care,
Julian
