Hi, Very interesting!!!! I have the same set of speakers for years now. I bought them second hand. The enclosures are self-build but not well designed. So I consider to build new boxes. I wonder how the horn design worked out for you.

I'm interested in a copy of the hifi news and record review article as you showed in the pictures. Do you have a design of the Original Concerto as well.
(if some other reader has a copy of these articles for my you make my day as well)

thank you,

Willem

My neighbour used to have the KEF Concerto's.

I cleaned them up for him one day. Just tidied up the wiring to fresh metal really. Sounded pretty good afterwards. We listened to "Graceland" by Paul Simon. That smooth, if unexciting, old bextrene sound.

FWIW, Wilmslow Audio and Falcon Acoustics offer upgraded crossovers more along later KEF ideas.

Default Kef B200 transmission line subwoofer

I didn't read the whole thread, but if someone is trying to replicate the Kef B200 stereo transmission line subwoofer...I own an original. Someone can take measurements. It came as a sub satelite system sold by Fried speakers. I don't remember it been sold by Kef directly.
As far as the grand daddy sub of the era, the coffin sub with the kef B139, I heard one and almost purchased it, but didn't because of its size. I wish I had it now.

Default cannot find the article

I'm very interested in the folded system using these speakers.
Can anyone provide the article mentioned in the first post?

“HiFi News & Record Review” from May 174 entitled “A Folded Column Loudspeaker”.

It would be appreciated enormously

Thank You,
Willem
