Check out this wonderful art installation in Croatia featuring tractrix horns and battery powered amps. The artist Matija Blažičko sent some pics to use for Retro Hi Fi Girl Friday but I thought it was too cool for that. Featured in the pics is his sister. Her site here.
From the Artist.
The work Emanation was exhibited in june this year in the chapel of saint Rocco in Zagreb, Croatia.
It was my humble attempt to recreate feeling of big cathedral in small chapel.
Benjamin Britten's Festival te deum played, It was all about the
experience of hollographic imaging and stereo separation (I got inspired
by the Chesky records ultimate demonstration disc)
Main horns follow tractrix curvature and are made of "artificial
marble" composite. They hang freely in the air by the kevlar strands.
Frequency response extends below 80Hz but are digitally crossed over at
80Hz from where the pair of hidden subwoofers take over. Amps work on
battery banks so the problems with "dirty" mains are altogether
This image I believe is from the late 60's Stereo Review. If you know the origin please let me know. Klipsch liked it so much they turned it into an advert.
Additional info from Bruce.
The photo originally came from the Feb 1969 issue of Playboy magazine.
It was the lead photo in an article titled “The Sights and Sounds of
69”. The article described “the latest and best in Hi-Fi and TV”
and had numerous recommendations for differing budgets. The K-horns
were in the top of the line system and were quoted as costing $804 each.
The Cornwall used for the center channel was said to be sold for $415.
Other pieces from this system were a Marantz Model 7T Pre-amp and dual
Marantz power amps.
“I like big horns and I cannot lie, those little horns make me cry” Tom Danley "Simple. A horn is just a reasonably rigid boundary for an air column. Now all you have to do is figure what shape to make it." PWK
