I am looking for info on the subject listed speakers. I acquired a mint condition pair, there seems to be no info anywhere on the web...nothing. even wharfedale uk hasn't been much help. They were built somewhere around 1970, they are a rear firing speaker, somewhat similar to the klipschorn design. Cabinets are beautiful mahogany, the woofer fires up, with a sphere object that is adjustable for the mids and highs to "fire against". any info anyone has on these speaker would be appreciated. I am a newbie to the audiophile world. THANKS!
