Simply, a speaker (for any electronic source, example Organelle) without a speaker cone.
I have tried the prototype a couple of times, different locations, from small to bigger rooms, (example studio in IRCAM to main Auditorium at Superbooth18) connected with many electronic instruments and was always a very rewarding experience, not only sonically but also sensory when it is in direct contact (ONDES+playing instrument)
Its still in countdown… but I can’t wait!! to have a bit of the acoustic world closer.
Note: I don’t have any affiliation with the project, just meet the creators, plan to back it when its live and yeah lets wait for more information.
