Raidho TD4.8

The TD4.8 is built on the MTM concept as the TD4.2 but delivers a more extreme sound.

Raidho TD4.8

This impressive speaker delivers world class musical experiences that captivate the listener.

The TD4.8 is build on the MTM concept as the TD4.2. This is just even more extreme designed as a true full-range speaker using our in-house made Tantalum Diamond-drivers with no less than 6 bas-drivers and 2 midranges.

‍

Together with the upgraded TD-ribbon tweeter this impressive speaker delivers world class musical experiences that captivates the listener with a huge soundstage capturing the atmosphere and intimacy of your recordings.

‍

Placed on big adjustable feet with built-in decoupling the TD4.8 will make the best out of any room with the stunning looks and the sound is fast coherent and authentic. The TD4.8 was appointed the ”Cost-no-object speaker of the year 2018” in Hi-Fi+ and it is a testament to all musiclovers.

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.

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.

“One quick blast of the Raidho TD-4.8 and you’ll know precisely what type of instrument is being played almost to the point of knowing what kind of reed the musician prefers.” That might seem like hyperbole until you sit and listen to the TD-4.8 played well and realise that detailed insight into the music is compelling and powerful. So powerful in fact you’ll struggle to tear yourself away: “turning the track off was an act of musical barbarism. Pick an album play track one intending to listen to only that track. Five tracks later you are still mesmerised and reaching for the ‘Stop’ button is like disrespecting the music itself.” Wow just wow!”
