Just bought a pair and wondered if anyone can tell me something about them. I'm told they are good with valve amps in mind.Not sure about their spec tho.

Posting a question about a speaker from 1960 will get little response in a forum dealing with speakers form the 1970's, however follow this link http://www.kef.com/history/1960/duette.htm for the "techie" bits. If your T15's are sibilant they're probably damaged as they normally have an unassertive sound like their younger sibling the T52.

I had no idea this forum only covered speakers from the 1970s onwards which begs the question --why?

I dont think the tweeters are damaged simply because my cd player sounds fine, so I thought the cartridge may need replacing . These speakers may be more revealing than my previous Heybrook hb1s..

As I also use a Leak stereo 20 and an audio innovations 800c pre I am thinking that the leak is too sensitive for the AI which , I think , is an active pre. Therefore a change to a passive may yield the corr4ect results re treble? Question
