Raidho Acoustics has announced a series of loudspeakers named TD Signature. According to the manufacturer, these models take reproduction to a higher level by applying the lessons learned from Raidho's flagship, the TD3.10 reference loudspeaker, to the TD1.2, TD2.2, and TD3.2.
According to the designers, the TD Signature models are aimed at refining Raidho's platform, which they describe as already uncompromising. Raidho presents these models not as a change of course for the TD series, but as a series of improvements intended to ensure that existing designs fade even further into insignificance—that is, that the speakers disappear and only the reproduction of music remains.
The core of every TD model is Raidho's layered cone construction, which is a combination of aluminum, a ceramic coating, tantalum, and artificial diamond material. Each layer is said to have a different function: aluminum contributes to speed and shape stability, ceramic provides hardness and control, tantalum provides damping and balance, and the diamond layer increases stiffness and resonance control.
That diamond material is used in Denmark at the Danish Institute of Technology in Aarhus, underscoring Raidho's long-standing focus on highly specialized, locally controlled driver development. As always in this market segment, the technical aspects are as much about what the loudspeaker takes away as it is about what it adds: less stored energy, less coloration, and fewer obvious signs that the enclosure and driver system are getting in the way.
For the TD Signature upgrade, Raidho has added Furutech terminals, revised the crossover filter based on the experience gained during the TD3.10 project, and refined the woofers with a softer suspension. IsoAcoustics feet are now also part of the package, intended to improve mechanical isolation from the floor.
Morten Kim Nielsen, CEO of Raidho Acoustics, said that the goal was not to make the speakers sound different, but to make them “disappear even more”.
The TD Signature models are expected to be available from July 2026. Prices start at 24,000 euros for the Raidho TD1.2 Black Signature and rise to 26,500 euros for the versions in walnut burr wood or a personalized color. The TD2.2 Black Signature retails for 45,000 euros, or 49,000 euros in walnut burr wood or a personalized color. The flagship TD3.2 Black Signature changes hands for 69,000 euros, and this amount rises to 75,000 euros for the versions in walnut burr wood or a personalized color.
