Tangent RS6 pictures.

  These beautiful speakers came to me when a friend of the blog pointed me to a Craigslist ad seeking a new home for them. I sanded the tops, which were very scratched and had watermarks, restored the sides, and put new grill cloth on the frames. I really can't complain about a missing badge.

  The Thunders Tangent reference site shows that the RS6 had KEF T27 tweeters  and Audax woofers. This pair has Audax tweeters. They were obviously installed at the same time as replacements for blown T27s (KEF changed the 104 to the 104ab in part to protect the T27s), and these Audax units were an excellent (and obvious) choice (as pictured, they're used in many excellent Mission speakers among others…the identical tweeter, with rectangular faceplate, is used the the Spica, and my beloved Rega 3s). These speakers sound very nice, with good bass extension (if not control), being driven by my Arcam Alpha as I write.
Update: swapping in the Arcam Delta 60 for the Alpha improved bass control and articulation a lot…makes sense.
