Classic 2 and Exact

Equipment feets with many nuances in detail and an excellent performance. The energy from the device can be removed easily and in this corpus will then be reduced without vibrations that penetrate the underground. In combination with the optimized footprint these absorbers are a good medium to facilitate a better acoustic pattern to Hifi-device, especially CD-players, tube devices and preamplifier as well as loudspeaker will benefit of them.


Alto Extremo Classic 2 Alto Extremo Classic 2

Classic 2

The Classic 2 is a completely new development. It has been optimized in many respects. The coupling to the device, damping and dissipation have been significantly improved. The Classic 2 is very well suited for appliances and especially for tube appliances. Thanks to its design and optimized footprint, the Classic 2 has a higher damping effect and can therefore also be used in racks with glass or stone floors. The overall height has also been significantly reduced, making it easier to use.

Alto Extremo Exact 1 Alto Extremo Exact 1

Exact 1

The Delrin body, the bronze ball and the stainless steel puck combined make an excellent and effective combination of materials. In combination with the optimized platform the Exact 1 is a very good product to lend hi-fi devices and loudspeakers superior sound quality with precise three-dimensionality and differentiated dynamics. Through his M4 thread it can be directly mounted.

Alto Extremo Exact 2 Alto Extremo Exact2

Exact 2

The big brother of the Exact 1. A larger housing, the optimized material mix and the resonance lead on the ball support, the Exact 2 is slightly better than the Exact 1 in all respects, without neglecting its precise three-dimensionality and differentiated dynamics. The Exact 2 sounds adult and can damp vibrations even better than the Exact 1. An expert in hi-fi devices and speakers.
With M4 thread for direct mounting.

Safety & GPSR Compliance Information 

1. General Safety Information (GPSR‑compliant)

  • The product is used for mechanical decoupling and vibration damping of HiFi devices, loudspeakers, and racks.
  • For stationary indoor use only.
  • Devices, loudspeakers, or racks must stand stable and centered on the absorbers.
  • The surface must be level, load‑bearing, and non‑slip.
  • Keep children and pets away (risk of tipping).
  • Heavy HiFi devices, loudspeakers, and racks may fall when lifted → risk of crushing; installation may require two people.
  • Do not use on wet, flexible, or unstable surfaces.
  • Do not use chemical cleaning agents.

2. General Warnings

  • Caution: Point loads may damage sensitive furniture surfaces.
  • Caution: Improper positioning may lead to instability of the device.
  • Caution: Not suitable for devices whose housings are not designed for point‑load support.
  • Caution: Not to be used as load‑bearing supports for other objects.
  • Caution: Outer damping rings may transfer color — check before use.

3. Operating Instructions

1. Preparation

  • Switch off the device and disconnect it from the power supply.
  • Disconnect loudspeakers from the amplifier.
  • Empty the rack and remove all connections and cables.
  • Clean the surface.
  • Check the number of absorbers required (typically 3 or 4).

2. Positioning

  1. Place the absorbers at the designated points.
  2. Carefully lower the device, loudspeaker, or rack onto the absorbers.
  3. Check whether all absorbers are evenly loaded.
  4. Perform fine alignment.

3. Operation

  • Operate the device as usual.
  • If audible changes occur, check the positioning.

4. Maintenance

  • Regularly inspect for dirt or damage.
  • Clean only with a dry cloth.
  • Do not use oils or lubricants.

4. Care and Usage Instructions

  • Store absorbers in a dry environment.
  • Protect from heat sources.
  • Do not use aggressive cleaning agents.
  • Replace in case of material fatigue or damage.

5. General Labeling Requirements (GPSR)
