Raidho TD1.2 Stand Mounted Speakers

TD Series Driver

This is truly a unique and revolutionary drive unit! 100% developed and built in-house by Raidho. The goals was simple: no coloration and outstanding dynamic capabilities.

The motor comprises of a very strong magnet (N52Neodymium) with an unseen even magnet field, coupled with an under hung titanium voice coil. This arrangement gives the drive unit the most powerful underhung magnet system in the world. The benefit from an underhung voice 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 eliminates 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 otherwise smear 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.

Legendary Raidho Ribbon Tweeter

Raidhos proprietary, trademark ribbon tweeter is a unique design. It is completely designed and built 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 extremely low weight of the foil (20 milligrams).

The result is virtually no resonances or distortion, and the breakup point is at an incredible 82 KHz! What you hear is amazingly clear and natural sound. All the detail in the world, but no fatigue, no distortion, and no coloration!

For the TD series, Raidho looked at how they could improve the tweeter to match the new drivers. A redesign of the magnets, waveguide, and rear panel to optimize airflow, helped them  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 their world-class tweeter even better.
