Raidho TD Signature – an Updated TD Speaker Series with Technologies from the Flagship TD3.10

Danish company Raidho Acoustics has introduced its new TD Signature series of loudspeakers. The lineup includes three models – TD1.2, TD2.2 and TD3.2 – which have received a number of engineering refinements based on solutions used in the development of the top reference loudspeaker system Raidho TD3.10. At the same time, the company emphasizes that this is not a complete rethink of the TD series philosophy, but rather a more subtle and mature evolution of it. The main goal of the update is to achieve even greater transparency, naturalness and freedom of sound, allowing the loudspeakers to “disappear” into the room as much as possible and leave the listener focused only on the music.

The key element of the TD Signature models remains Raidho’s proprietary multilayer driver diaphragms. Their construction combines aluminum, a ceramic coating, tantalum and an artificial diamond material. This architecture makes it possible to bring together several important properties: the aluminum base provides fast response and shape stability, the ceramic layer increases rigidity and control accuracy, tantalum helps suppress unwanted resonances, while the diamond coating further increases stiffness and allows the drivers to operate with high precision.

The diamond material is applied at the Danish Technological Institute in Aarhus. In this way, Raidho retains control over one of the most important stages of production and highlights the local nature of its driver development. According to the company’s concept, loudspeakers of this class should not only add scale, resolution and dynamics to the sound, but also remove everything unnecessary – coloration, accumulated cabinet energy and any sense that the sound is coming from a specific physical object.

In the updated TD Signature series, Raidho’s engineers have reworked several important components. The loudspeakers now feature Furutech terminals, upgraded crossovers developed with reference to the work done for the flagship TD3.10, as well as updated bass drivers with a softer suspension. In addition, IsoAcoustics feet are now included in the package, designed to improve the mechanical decoupling of the speakers from the floor and reduce the influence of vibrations on the final sound.

The Raidho TD Signature loudspeakers are scheduled to go on sale in July 2026. The entry-level Raidho TD1.2 Black Signature will be priced from €24,000 per pair. Versions finished in walnut burl or a custom color are priced at €26,500. The Raidho TD2.2 Black Signature has a recommended retail price of €45,000 per pair, while versions with extended finish options will cost €49,000. The flagship model of the new lineup, the Raidho TD3.2 Black Signature, is priced at €69,000 per pair of loudspeakers. Versions in walnut burl veneer or a custom color will cost €75,000. Thus, the TD Signature series takes its place among Raidho’s most expensive and technically advanced solutions, offering buyers a refined version of the already established TD lineup with an emphasis on cleaner, freer and more natural sound.
