Description

This is a pair of Tesla T2 driver units in 50mm diameter with Beyerdynamic T1 G2 diaphragm and Tesla driving technology. Together with the driver, we provide a pair of acoustic finetune plugs so you can easily adopt the driver with your headphone shell. We recommend using Tesla T2 drivers to repair or upgrade most mid-high close back headphones for premium sound quality. 

Know about Tesla driver  

(cited from headphonezone) Scientists define Tesla as the unit of magnetic induction or magnetic flux density in the metre-kilogram-second system (SI) of physical units and it was not until 1960 that it was named after the electrical engineer Nikola Tesla. ‘Tesla’, for Beyerdynamic’s headphones, stands for the latest system technology that is distinguished by a very powerful magnetic drive and clean reproduction with a low degree of total harmonic distortion.

The Tesla unit presented Beyerdynamic with a daily challenge, since values in excess of one Tesla are deemed to be difficult to achieve in the construction of headphones. Here, every increase of the so-called flux density can provide immense advantages. The voice coils can be more filigreed and consequently react more quickly, while the sound generated gains precision and richness in detail. At the same time, the energy utilization increases and the listener can play music louder. In other terms, the more the coil is for the driver, the greater details it can push out.

 

What can you achieve with the powerful magnetic driver? Simple, it can be used to design the voice coil that generates more filigreed sound. This is where sound benefits by gaining extreme richness of detail. On the other hand, the additional magnetic power can be converted into acoustic energy, giving the reproduction more power and impact. So, Beyerdynamic takes advantage by fully utilizing the headphone driver’s coil without any loss in efficiency. It does not matter even for the lower impedance headphones, it can still convert as much magnetic power as possible into acoustic energy.

This also helps in protecting your ears. Normally, people pump-up the volume considerably to listen to the details. This may adversely affect your ears in the future.

Well, the good thing about a high level of efficiency is that it is also effective at lower volume levels, providing a nuanced and more detail-rich sound, which means that you do not have to crank up the volume too high in order to listen properly.

The strength of the magnetic field in a headphone system should not be confused with electromagnetic radiation. Inside the headphones, there is a static magnetic field, similar to the earth’s magnetic field, which is also concentrated upon a tightly limited area: the air gap with the voice coil. So, you need not worry about the magnetic action affecting your brain or health in any way.

Tesla systems are indeed optimized so that as little magnetic power as possible escapes from the system, because this would be a loss in efficiency. Naturally, audio signals in the voice coil generate a tiny degree of electromagnetic radiation, as is the case with all headphones. But this is lower than with conventional systems anyway, because the high degree of efficiency requires a very small level of power.

A particular highlight of Tesla technology headphone is its design as a full metal system. It prevents any uncontrolled resonation by parts of the casing leading to distortion of the sound. Apart from that, the metal shields the construction from electrical disturbance fields. In a Tesla headphone, the only thing that causes the membrane to emit sound is the musical signal itself.

Thus, it can be said that the creation of these Tesla-powered headphones by Beyerdynamic was an eye-opener for the headphone industry.

Measurement and DIY suggestions

The acoustic fine tune plug helps you manage the sound character – if you feel the driver being too bassy, you can apply this plug in to the central hole and further block 1 to 4 tiny holes on the plug, until you fell satisfied.

We highly recommend using this driver with close back shells like our Model B9 to 100% reproduce the Tesla sound. Most popular gaming and Bluetooth headphones are with closed shell so the upgrade is very straight forward. 

Also note although with 120Ohm impedance, Tesla T2 driver is with  decent sensitivity and can be easily driven by most cell phone – of cause desktop or portable AMPs with 200mW+ output are always preferred.

 

 

Note: the dynamic drivers have been paired to ensure sound and quality fully balanced between right and left channels. Therefore we don’t offer single unit.  

Soldering: overheated (>250 degree C) soldering iron or overtime soldering (>2s) may permanently damage the driver. Please managed down both in your DIY. 

  • Installation: the driver has Sintered NdFeB Magnetic inside with extremely strong attraction power. Damage may caused by attracting anything hitting the fragile diaphragm. 
  • Others: applying high-voltage, storing in high temperature/humidity environment… all may cause unrecoverable damage.
