I’ve been following Kondo Audio Note. They hosted a music listening event recently with a variety of Audio Note equipment where anyone could join. I’m always curious in terms of the speakers they use, I couldn’t identify them but posting a photo for everyone. They seem like horns in a massive custom open baffle (am I wrong?). Interesting, very much a purist choice.

where was this ?

At the Audio Note offices outside of Tokyo as far as I understood.

I think that there is a big 15"(?) woofer on that open baffle + hornloaded tweeter.

(If they were mounted into a room wall, it would be 'infinite baffle' )

Thanks Owen! Mystery solved, they are Siemens Eurodyn old cinema speakers (older single-woofer version). More on these:

Interesting topic belbo. They look like open baffle speakers, I wonder how that worked in cinemas?
After trying a number of designs, I like 2 way (with compression horn), and it seems this format is still popular, though mostly vintage gear. I suppose houses (and speakers) are getting smaller...with digital trickery becoming more accessible.

Would that be mostly custom made? What are your preferences? Indeed the problem with horns would be size.  

Size? How true! She Who Must be Obeyed put her foot down on these and said under no circumstances would they be allowed in the house. Shame really!

My advice:
Pitch for these first.
You can negotiate from there

Not really, just standard 2 or 3 way, one pair was transmission line, the last were 10" full range in a DIY bass reflex cabinet. I've settled on the Altec 2-way...the realism of the compression horn and good bottom end from the Alnico woofer and large enclosure, but they are large. Do you have any preference for loudspeaker format? 

Those "interesting" images above remind me of the Total Dac set-up covered in this short article...(apologies for the link)
