I've had these speakers for over twenty years, and for most of them the volume
selector has been awful. The speakers themselves are fine, a simple enough pair
of small stereo speakers with an accompanying subwoofer, but the volume selector
is a plastic wheel set in-line with the speaker cable which — when rotated to all
but a few narrow positions — fails to make a solid connection and leaves at least
one of the two speakers cut out. I've put up with it for quite a while, the
positions being good enough and stable enough to enjoy it, but now that I've got
a proper electronics hobby and am far less shy about cutting wires apart I'm

Cutting the wires and unscrewing the case, the dial was revealed to be a very
simple 10kΩ potentiometer. While this could /easily/ be replaced with a newer,
prettier knob, there's just no fun in so simple a project. Indeed, why not have
it controllable via WiFi? Or select multiple inputs? I'm using it primarily for
my turntable right now, but I've got a TV nearby, and it'd certainly be nice to

pipe my computer's audio through it when I feel like it.
