I will add this, in fairness: Even into their later days, the company started by Hermon Hosmer Scott did produce a surprising number of surprisingly
pleasant loudspeakers. Some of the "surprise" reflects the rather prosaic design of most of them.
The 166, which by the way dates from the late 1970s, is a fair example.
The earlier S-15, I would opine, is an even better one. An astonishingly generic looking sealed box (
monkey coffin) three way loaded with three inexpensive and unremarkable cone drivers (at least two if not all three of them sourced from the well known driver manufacturer CTS, which was a forebear of today's Eminence company, if memory serves) and a "controlled impedance" crossover network (which I never looked at, truth be told).
I had a pair of these (dump finds) and they were
exceptionally pleasant to listen to. They were also surprisingly sensitive (given their rather small sealed enclosures) and easy to drive. I would have them still, probably, but I gave them to a local teacher who was setting up a small, simple, robust stereo for her classroom.
