Only contact remains.
The only system that modulates vibrations where others cannot reach: the low frequencies.
The zone that defines fatigue, stability, and truth of motion.

How it works
Low frequencies
The only system that impacts low frequencies, reducing the deep shock of the frame.
Sensation enters the court
Filtering vibrations enhances sensitivity. The racquet stabilizes, the arm feels lighter.
It reads every vibration
Different cells respond to different frequencies. It preserves the useful ones and removes instability.
Form is function
The metamaterial deforms on impact. It’s the geometry that reacts, not the mass, shaping sensation with precision.
Sensorial Technology
AMbelievable™ 3D-printed metamaterial: precision that enters the court.
We analyze the racquet’s behavior, mapping its critical frequencies with precision.
With metamaterials, we program the response through intentional geometric design.
3D printing engraves every detail: its precision becomes control on court.
The geometries activate on impact. They filter the superfluous and amplify the contact.
Stability is measurable:
the data proves it.
Low frequencies weigh on the arm; mid and high frequencies blur the feeling.
Universal remains the most effective — in data and on court.
* Independent analysis by HEAD acoustics, a global authority in vibration science.

The difference isn’t in the name.
It’s in the response.
| Feature | Universal | Other Devices |
| Low Frequencies (0–150 Hz) | ✔︎ Reaches them | ✖︎ Cannot |
Mid and High Frequencies (500–1200+ Hz) | ✔︎ Reaches them | ✔︎ Reaches them |
| Natural Feel | ✔︎ Preserved | ✖︎ Muted |
| Impact Precision | ✔︎ Greater stability | ➖ Variable |
| Arm Stress | ✔︎ Lower | ✖︎ Higher |
The difference, in their words.
Traditional dampeners made me lose feel.
This one doesn’t: it removes the noise, not the sensation.
It’s much lighter than what I used before.Less vibration, better control.
I can actually feel the ball — not muted, but clear.It’s like the shot becomes more readable.
I received it as a gift and now use it on several frames.
Cleaner sound, unchanged balance — as a stringer, I appreciate that.
I thought it was just another dampener.It actually changes the sensation: the racquet feels more stable.
And unlike others, I haven’t lost it once.
I normally hate dampeners, but this one gave me more feel and control right away.
More stability, especially at net and on serve.
Feel the difference yourself

Details that matter.
If something’s not clear yet, it’s here.
Yes. An independent Head-Acoustic study showed Universal outperforms competitors across all frequencies — including part of the low-frequency range generated by the frame.
Other dampeners simply do not reach them. The data is clear.
A cleaner impact. The “right” vibration remains; the disturbing one disappears.
Your shot becomes clearer, more stable — and you feel the ball more.
Sure! Universal keeps your feedback intact and removes only the vibrations that disrupt the shot.
If you dislike metallic noise and want a more refined feel, you’re in the right place.
No problem. Try it on court, if it doesn’t convince you, the return is simple, fast and fully refunded.
We’re tennis players too: we want you to feel the difference, not feel pressured.
We just ask that you test it for a few sessions to truly understand its behavior.
If not, call or message us, we’re always happy to help you.
