I had a pair of those in my first good system. A nice little Onkyo receiver, Technics TT, two Denon cassette decks, and the Minimus 7s. I even blew a woofer once and bought a replacement driver off the shelf at the local RS. They made nice bass for their size.
I seem to remember that the ones I had cost $49 each. Maybe it was a different version?
We had a local audiophile guy come to a meet last year who's passion was modding those little RS speakers. He brought a couple different pairs along to play. He was an odd fellow, but very passionate, and loquacious.
