I think Radio Shack sold them as outdoor/patio type speakers when I
bought them and I seem to recall the name "Minimus-7".

Tim, you might also search for the name "Optimus" Same cast Al case and
speakers with internal crossover networks. Same speakers as the Minimus,
different timeframe. IMHO, neither sound near as good as a good set of
stereo phones, but agree that it's easier to demonstrate to visitors using
the speakers.
