Cambridge Soundworks was founded by Henry Kloss, the K of KLH. Their model Six was Kloss's recreation of the KLH Model Six. I do not think they are made any more, but , you might be able to find them on eBay or,depending on where you live, on Criag's list locally. Just check the condition of the surrounds if they are old. In the Boston area they are usually less than $100. They have 8" woofers which are pretty much not used in modern designs at this price point. There are lots of decent speakers in this price range but the Model Six might be appropriate from a nostalgia perspective.
Just looked on eBay and there is new pair for $119. No affiliation.
