"Axial Triphonic Speakers" from Lys Audio
The demo was conducted with the speakers behind a curtain, and consisted of a recording that included nature sounds as well as music. The sound was certainly dynamic, the bass particularly powerful, and the imaging waswell, strange. According to Gérin-Lajois, that's because we're used to the artificial "stereo" imaging of conventional sound systems, and once you listen to his system for a while it will seem natural and conventional stereo will sound wrong. Although I was not allowed to take pictures of the speakers behind the curtain, but Gérin-Lajois did show them to me; they consisted of a ribbon tweeter, horn midrange, and a large box woofer, side by side. The price of the system is expected to be about $30k, and the placement of speaker components can be flexible to suit the environment. Time will tell whether audiophiles will come to accept this radical departure from two-channel and multichannel sound reproduction.
