Henry Kloss, who was with AR, KLH (he was the "K") and Advent, later co-founded Cambridge Soundworks. I used to frequent its factory store in Newton, MA. I acquired a dozen Cambridge Soundworkds speakers two 12" amplified subwoofers and 3 of their radio/CD players (which sounded much better than the Bose Wave radio at half the price), One pair of speakers was a copy of the famous KLH 6 that I have to this day. The man had an amazing career and designed some innovative speakers, including the AR 3A, the KLH 6 and the Large Advents.
What Have I Bought?
I saw a pair of large Advent speakers listed on CL by a seller whom I've bought other items from before. The pictures looked like the bullnose version of the speakers, and that's all I needed to know. The pictures showed the speakers to be in almost-mint condition, so I plunked down the money via PayPal and drove the 70 miles to pick them up the following weekend. I was more than pleased when I saw them...even the documentation (2 sheets) on the back of the speakers was in near-mint shape. Gorgeous walnut cabinets, but they weren't the bullnose edition specifically, although they did have a beveled front that is semi-bullnose. I know that Advent produced several versions of the large model and am not sure which one these are. The sound is to die for....flat, uncolored, and unbelievably well-balanced. Doesn't stand out in any particular way, but you just want to keep listening for hours. Anyone that might recognize which model these are please respond. Henry Kloss was a flat-out genius.
