Raidho TD3.8

RAIDHO-TD3.8
Colors
The midrange is handled by two 5” drive units. They are placed in a MTM configuration to further lower distortion, lower crossover points and control the dispersion. The lower distortion and broadband performance will reveal every layer of music to you.

‍The massive crossover is placed in the bottom, and all acoustical treatment inside the TD3.8 is carefully measured and matched for absolute performance. The crossovers them selves are pieces of art, that deserves the day of light.

‍The TD3.8 is the one to beat in this class. The power and magnitude is equally matched with timing, phase and coherency in a full-range design that is musically authentic, real and extremely convincing. Audition the TD3.8 and discover what you have been missing...

Raidho Series TD Drive Unit

This is truly aunique and revolutionary drive unit! 100% developed and built in-house by Raidho. The goals was simple: nocoloration and outstanding dynamic capabilities.


The motor comprisesof a very strong magnet (N52Neodymium) with an unseen even magnet field, coupledwith an underhungtitanium voice coil. This arrangementgives the drive unitthe most powerful underhung magnetsystem in the world. The benetfit from an underhung voiciecoil 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.

The Legendary Raidho Ribbon Tweeter

Proprietary 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 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!

Elegant Design by Raidho

The TD3.8 is built around two of our new 8” drivers, similar to the ones in the mighty TD6, reproducing its stunning dynamics.
