Why it exists
Extreme performance for the price, expressed through compact dimensions, proprietary technology and Danish craftsmanship.
The TD4.10 was created as a new summit of the Raidho philosophy: a loudspeaker for systems and rooms where no meaningful limit should remain between the recording and the listener. It brings the company's proprietary ribbon tweeter, diamond-coated driver technology and uncompromising Danish construction together on a truly reference-scale platform. Its purpose is not simply to play louder or reach deeper, but to preserve speed, coherence and tonal truth while reproducing the physical dimensions of live music. Vast energy must arrive with control; the smallest details must remain natural rather than exaggerated. TD4.10 is intended for listeners seeking the ultimate expression of scale, presence and emotional realism from a Raidho system. It exists to move beyond conventional high-end expectations and make even the most demanding performance feel immediate, effortless and fully alive.

The TD membrane combines five carefully engineered layers: an aluminium core, ceramic surfaces, tantalum and a final coating of artificial diamond. Each cone carries approximately 1.5 carats of diamond in a layer measuring only 10 microns.
five-layer cone · tantalum · 1.5-carat diamond coating
The tantalum-and-diamond structure is up to 50 times stiffer than a ceramic-only membrane. Resonances are reduced by 36 dB, while the first breakup mode is raised to 20 kHz, leaving the audible range exceptionally clean.
50× greater stiffness · 36 dB resonance reduction · 20 kHz breakup
An N52 neodymium magnet drives an underhung square-wire titanium voice coil with exceptional linearity. The turbine-shaped motor and open basket minimise reflections, while copper-coated pole pieces reduce inductance, delivering bass with speed, authority and precise timing.

Why it sounds different
The Raidho planar-magnetic tweeter brings together the best of two worlds: exceptional detail and resolution combined with a smooth, natural musicality. With virtually no distortion or coloration, nothing stands between you and the music.
planar magnetic · ultra-low mass · fast response
The redesigned construction increases sensitivity by three decibels, giving the tweeter greater freedom to follow the exceptional speed of the TD drivers. From the finest microdynamics to sudden musical peaks, the entire loudspeaker responds as one coherent voice.
+3 dB sensitivity · effortless dynamics · seamless integration
Already minimal distortion has been reduced by a further 35 dB in the TD design. Fine textures, harmonics and spatial information are revealed without hardness or exaggeration, creating exceptional resolution that remains natural.
35 dB lower distortion · high resolution · fatigue-free sound
