Raidho TD3.8

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

Raidho TD3.8

This will entangle you in the roots of the music full of authentic real-life dynamics that is as live and engaging as going to a concert.

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...

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.

POSITIVE FEEDBACK:

“To say that my first couple of months with the TD 3.8s was splendid would be a gross understatement. It’s rare that I have been so pleased and impressed with a new loudspeaker design.”

ENJOY THE MUSIC:

“Very highly recommended with a cherry on top!”

THE ABSOLUTE SOUND:

“The TD3.8s have some of the smoothest and most musically natural timbre I’ve heard and are remarkably consistent from the lowest-level passages to the loudest and do not vary as the music becomes more complex.”
