RAIDHO ACOUSTICS TD6

Although it looks very much like the acclaimed D5 and D5.1. The TD6 is a completely new development, only parts of the visual appearance resemble the previous models.

The modularly constructed cabinet system is capable of delivering unprecedented low-frequency clarity and speed, natural tonality and texture. It's the foundation that allows the TD6 to bring artists and their playing to life; the energy of a bowed double bass or the crisp snap of a snare; the searing edge of a twinkling guitar solo or the whisper of the most intimate voice; allowing you to feel the music as well as hear it. The TD6 is the one that does it all.

‍In the TD6 version the tweeter blade has been upgraded to handle even more power and higher dynamics.

Certainly it is a large and highly sophisticated loudspeaker, but at Raidho they prefer to think of their flagship as a musical time machine: Choose a concert, any concert, and the TD6 is able to transport you there, seducing the listener. You are transported to another time and place to forget everything around you. In short, this is a world-class reference loudspeaker.

The Raidho TD Driver 

A truly unique and revolutionary drive unit! 100% developed and built in-house by Raidho. The goals were simple: no colouration and outstanding dynamic capabilities.

The motor consists of a very strong magnet (N52Neodymium) with a uniform and invisible magnetic field, together with a suspended titanium voice coil. This arrangement provides the drive unit with the world's most powerful suspended magnet system. The benefit of a suspended voice coil over the traditional suspended voice coil is that it is much more linear and has better dynamic capabilities. The result is a perfect transient response with no measurable distortion.

To further improve the strength of the magnetic motor, they designed a new titanium voice coil using a square-shaped wire that eliminates air in the voice coil windings. This leaves no possibility for air gaps to interfere with the magnetic field. The entire magnetic system, as well as the basket itself, is turbine-shaped, which eliminates sound reflections that would otherwise taint the original sound. The solid copper on the inner pole piece very effectively minimises the inductance and linearises the impedance. The suspension parts are as soft as possible to ensure the least mechanical restriction to diaphragm movement.

Finally, a drive unit that can really keep up with the Raidho ribbon tweeter and make it all sound as one.

The legendary Raidho ribbon tweeter

The proprietary ribbon tweeter is a unique Raidho design. It is completely designed and hand-built in-house in Denmark. To be exact, it is a planar magnetic tweeter due to the tracks in the foil. The foil has a thickness of 11 microns, which means that it has a mass 50 times less compared to a conventional dome tweeter. This is due to the fact that there is no voice coil and the extremely low weight of the foil (20 milligrams). The result is that there is virtually no resonance or distortion, and the break-up point is at an incredible 82 KHz! What you hear is an incredibly clear and natural sound - all the detail in the world, but with no fatigue, no distortion and no colouration!

For the TD series, Raidho looked at how the tweeter could be improved to match the new drivers. A redesign of the magnets, waveguide and rear panel to optimise airflow helped increase sensitivity by 3 dB and reduce already low distortion levels by 35 dB. This raised the performance level even further, making this world-class tweeter even better.
