Ok, the model of my new Rogers is LS4a. One very brief review of these speakers that made me jump on the deal was from a Darko review of Harbeth P3ESR SE (
http://www.digitalaudioreview.net/2011/03/harbeth-p3esr-se-standmount-loudspeaker/). Here he says:
Well at a fraction of the Harbeth price, I thought I didn't have much to lose. I wasn't too impressed by the look though. I don't like black gear. Piano finish black maybe. But not just ordinary black. And that's what they are. The 20 something years didn't do favour to the current cab condition either. It was decent but not like-new. Well at least the drivers were in a pretty good condition.
