The presentation of complex musical pieces, such as classical or jazz, greatly benefits from a delicate and transparent rendering of the high-frequency range. Although adults typically hear only up to around 16 kHz, there is the so-called harmonic range above that, which we perceive indirectly. When properly integrated, it influences the character of all the instruments involved. Is it a Yamaha or a Steinway grand piano? A competent professional pianist or an exceptional artist? The harmonic range clarifies these details for us, bringing the virtuosity of the performance and the quality of the instrument closer to our experience.
Thanks to modern high-resolution audio media (Hi-Res Audio with extended dynamic range), the technical conditions are in place to realize this exceptional acoustic performance. Unfortunately, many speakers, even expensive and high-quality ones, are unable to fully deliver these high-frequency details into the listening environment. This is why the acousticians and engineers at AperionAudio decided to develop the Dual AMT Super Tweeter—the ultimate add-on tweeter designed to reproduce every facet of the upper frequency range with overwhelming clarity and precision.
The closed-cabinet design is expertly crafted, using only the finest materials. AperionAudio offers a five-year warranty, underscoring the confidence in the quality of their product.
Dual AMT (Air Motion Transformer)
Among the many concepts for building a loudspeaker transducer, the Air Motion Transformer is unique in its way of setting the air in motion. Many different transducer designs have been introduced throughout loudspeaker history. All have piston-like diaphragms that move the air in a 1: 1 ratio so that the diaphragm speed corresponds to the air speed.
The Air Motion Transformer, on the other hand, is an electromagnetic driver and is based on the Lorentz force, which moves the air in the individual folds. The membrane itself is printed with aluminum conductor tracks (violet arrows) and surrounded by a strong magnetic field. The resulting air flow (blue arrows) is four times (!) Faster than the movement of the individual folds. This offers huge advantages when playing music signals with fast transients (cymbals, plugged-in guitar strings, etc.).
Each Dual AMT Super Tweeter has two such AMTs, one at the front and one at the rear. This dual design ensures an incomparable spatiality in the sound and an even wider stage image.

Five selectable crossover frequencies
With the rear rotary control, you can activate the super-tweeter from a lower crossover frequency of 8 kHz, 10 kHz, 12 kHz, 14 kHz, 16 kHz or switch it off completely. This gives you maximum flexibility when you integrate the Super Tweeter into your system. You can more or less overlap your existing tweeter to lighten the sound from the 8 kHz or 10 kHz crossover frequency, or you simply let the Super Tweeter fill the gap above 14 kHz or 16 kHz.
Flexible sound adaptation
On the back of the Super Tweeter the sound can be further refined with the help of a second rotary knob. The treble can be adjusted from 0 dB to -5 dB in six steps. So the sound can be optimally adapted to your speakers, the room and your own taste.
Flexible connection terminal
The gold-plated connection terminals on the speaker backside ensure the best possible support for your speaker cables. The clamps also allow the connection of banana plugs or cable lugs. Thus a secure connection and best signal transmission is always guaranteed.
