A little correction the correct name for these speakers are BBC LS3/5a,Rogers was just one of the manufacturer.A few years back Rogers did remake these speakers which were the limited edition version, these speakers used better components for the crossover and have a beutiful finnish and I think only 50 pairs were made .Harbeth also came up with a Memorial Edition and so did KEF.
Rogers made the original higher ohm version, which is the highlighted model in question. The speakers were licensed by the BBC, but I do not beleive that 'BBC" was part of their namesake, at least they were not advertised with it in the name in the late 70's nor was is used on the paper labels on my speakers. The designation was LS3/5a and of course Rogers, the manufacturer. Just a little further correction.
Rademaker: There is some info at the following website as well as a reviewer who is an LS3/5a junkie. Other than this particular review on the Castle's and their comparison to the Rogers there should be another review "of" the Rogers as well. I previously owned the Castle Isis based on this review, which is fairly accurate. (http://www.AudioShopper.com/CastleIsis.htm)
There were also versions made by Audiomaster and Chartwell. I owned the Chartwell LS3/5a in the early eighties. I sold them in 1989 for $325. I should have held onto them. Seems they have really appreciated in resale value since they went out of production. I miss them. One of the best systems I had was the LS3/5a's driven by a 30w/ch Berning EA-230 tube power amplifier.
