Raidho will be exhibiting at Munich's High End show this week, and visitors to the room will be able to experience performances of the impressive-looking Raidho Tantalum Diamond (TD) 4.8 speakers.

These new speakers are fitted with drivers that not only improve on the company’s Ceramix drivers but also the Raidho Diamond drivers too.

As it stands, each Diamond driver takes around two days of continual processing to complete, we are told. However, never ones to stand still, Raidho were on the look-out for ways to improve even on these top-flight cones.

They discovered that, by adding 1 micron of Tantalum to the Ceramix membranes before the diamond layer is added, that this now 5-layer sandwich membrane is even stiffer than the Diamonds which is said to improve the inner damping of the membrane.

Furthermore, this means that the drivers act more like a piston without any break-up nodes within the hearing spectrum.

The Raidho TD-4.8 is the first step into the future using this new technology, and you will be able to hear it for yourself if you are attending the High-End show in Munich this week.
