Raidho TD Series - The Ultimate Loudspeakers
The TD Series is meant to be the last loudspeaker you ever buy. They are highly advanced, but it is not only about technology. It is about music and about expressing this art form. When you listen to a loudspeaker in the TD Series, you will experience all the emotions of music. An authentic and holographic sound will embrace you and transport you to the place where the music was recorded.
The crossover in the TD Series
The heart of any loudspeaker is the crossover. Because it is often hidden inside the loudspeaker, it does not always get the attention it deserves. But when it comes to Raidho, and especially the TD Series, the crossovers are small or even large works of art. Mundorf components are used extensively, and the way they are assembled and put together is breathtaking. They are hardwired, point
to point wired and made entirely by hand. The cables connecting all the components are Nordost cables. Even in the crossover! This is true proof of how far Raidho is willing to go in the pursuit of the ultimate in every single detail.
A revolutionary ribbon tweeter
In the TD Series, Raidho looked at how they could improve the tweeter to match their new drivers. By redesigning the magnets, the waveguide, and the back plate to optimize airflow, they have been able to increase sensitivity by 3 dB and reduce the already low distortion level by 35 dB. This raised the performance level even further, making their tweeter even better. And it was already world-class!
Internal cabling
All internal wiring in the loudspeaker is done with high-end Nordost cable with the famous monofilament. The standard is Norse technology, but it is also possible to upgrade to TSC from the Odin Series.
Custom colors
For the TD Series, it is possible to order the cabinet in your personal color to make the loudspeaker completely unique. All colors are possible, as long as there is a color code for them.
The construction of the TD chassis
This is truly a unique and revolutionary chassis. 100% designed and built by Raidho themselves. The goals were simple: no discoloration and excellent dynamic properties.
The motor consists of a very powerful magnet (N52 neodymium) with a uniform magnetic field, combined with a titanium voice coil. This arrangement gives the driver unit the strongest underhung magnet system in the world. The advantage of this is that it is much more linear and has better dynamic properties. The result is a perfect impulse response with no measurable distortion.
The entire magnet system and the basket itself are shaped like a turbine to eliminate sound reflections that would otherwise blur the original sound. The solid copper coating over the inner pole piece minimizes inductance very effectively and linearizes the impedance. The suspension parts are as soft as possible to mechanically limit cone movement as little as possible. Finally, a driver unit that truly works with the Raidho ribbon tweeter, can keep up, and makes everything sound as if it comes from a single driver.
The technical details of the TD diaphragm
This is a completely unique and revolutionary diaphragm. Raidho has worked together with the Danish Technological Institute to find the ultimate material for loudspeaker diaphragms. And we believe they have found it!
The diaphragm is a 5-layer sandwich construction. On top of the aluminum and the ceramic layer, there is a so-called tantalum layer. The final layer is an artificial diamond. Each diaphragm contains 1.5 carats of diamond, but it is only 10 microns thick. All of these materials contribute their own strengths to the mix, making these drivers completely unique.
The Ceramix diaphragms are produced in highly specialized machines, where argon gas is pumped in and particles are pumped out at the speed of light, causing the atoms to bond to the diaphragm. This forms the tantalum and diamond coating. TD coatings reduce resonance by 36 dB compared to ceramic and are 50 times stiffer than a pure ceramic diaphragm. The break-up mode has been increased to 20 kHz! Raidho is the only loudspeaker manufacturer in the world that uses this technology.
