The new Raidho Tantalum-Diamond (TD) cone: Even though our Diamond cone drivers, are already groundbreaking in their technology and performance, we still don’t stop there - improving our technology is simply a part of the Raidho DNA. With the new Tantalum technology, we have managed to better our already class leading diamond cones. By adding Tantalum to our ceramic cones, before the diamond layer, we have created a 5 layer sandwich cone, which is even stiffer than our already extremely stiff diamond cones, while at the same time adding huge amounts of inner damping. This means that these cones move completely like a piston without any break-up nodes way above the human hearing limit. (Actually even higher than most high quality tweeters) What we gain from this is lower levels of distortion than any other drive unit on the market, lightning fast transient response, matching our world-famous ribbon tweeters perfectly. The extremely low levels of distortion, also ensures a very musical and organic reproduction – bringing you closer to the music than you thought possible.
