Wrong from me!
It's Tidal-Audio.com, not acoustics!
Well, i think, i'm not 100% sure of prices!?
The Tsunami has Seas magnesium-diaphragm and S.P. revelator tweeter. Price is like Euro 18 000,-
The Tsunami Diacera with diamond tweeter and a ceramique Thiel and Partner mid driver, is Euro 35 000,-
These speakers has some sort of air-tuning,
system, adjustable in 3 steps.
The tuning has something to do with the "air-ports", in the speaker cabinett.!??
Well, the weight is ALOT, so they are most likely not resonant.
It seems nothing has been left for the wishlist, great componenets too!
Tweaked at arrival...who knows!?
I would very much like the Tsunami Diacera at home!
