Raidho TD4.2

The TD4.2 is first in the TD line with a true MTM configuration.

Raidho TD4.2

The sound is authentic and live delivering powerful music experiences.

This symmetrically build extends all the way to the bass. TD drive units makes the speaker ingulf you in a holographic landscape of sound.

‍

With multiple bass driver it may produce the same volume and go as deep as much bigger woofers just with much better impulse response resulting in a very dynamic and articulate sound. This also makes it possible to keep the front plate slim thereby reducing diffraction. This adds to a wide and precise sound stage.

‍

The sound is authentic and live and TD4.2 will deliver musical experiences from the smallest intimate performances and to the biggest bands with impact dynamics and musical scale in the most convincing of ways.

This is truly a unique and revolutionary drive unit! 100% developed and build inhouse by Raidho. The goals was simple: no coloration and outstanding dynamic capabilities.
‍
The motor comprises of a very strong magnet (N52 Neodymium) with an unseen even magnet field coupled with an underhung titanium voice coil. This arrangement gives the drive unit the most powerful underhung magnet system in the world. The benetfit from an underhung voicie coil over the traditional overhung is that it is much more linear and better dynamic capabilities. The result is perfect transient response with no measurable distortion.

To enhance the strength of the magnetic motor even further we designed a new titanium voice coil using square shaped wire that eleminiates air in the voice coil windings. Leaving no possibility for air gaps to interfere with the magnetic field. The complete magnet system as well as the basket itself is shaped like a turbine which eliminate any sound reflections which would otherwisesmear the original sound. The solid coppering over the inner pole piece very effectively minimizes inductance and linearizes impedance. The suspension parts are as soft as possible to insure as little mechanic restraints to movement of the diaphragm.

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

Our proprietary trademark ribbon tweeter is a unique design. It is completely designed and build by hand in-house in Denmark. To be exact it is a Planar Magnetic Tweeter due to the tracks in the foil. The foil is 11 micron thick which means it is 50 times less mass in comparison to a conventional dome tweeter. This is because there is no voice coil and the extreme low weight of the foil (20 milligram). The result is virtually no resonances or distortion and the breakup point is at an incredible 82 KHz! What you hear is amazing clear and natural sound. All the detail in the world but no fatigue no distortion and no coloration!

For the TD series we looked at how we could improve the tweeter to match the new drivers. A redesign of the magnets waveguide and rear panel to optimize airflow helped us to raise the sensitivity by 3 dB and reduce the already low levels of distortion by 35 dB. This raised the level of performance further making our world-class tweeter even better.

What the press is saying about the
Raidho TD4.2

ENJOY THE MUSIC AT THE AXPONA 2019:

“This system offered frighteningly realistic texture to voices with a sense of both space and body that was chillingly credible with instruments recreated in remarkably realistic size texture and tone. And for a speaker with such a narrow footprint it created a sense of dynamism you would not necessarily expect at first encounter. Microdynamic expressiveness was stellar approaching the best I’ve yet heard. “
