MAX-1

New in 2024
Alto-Extremo is now 20 years old and the MAX-1 has been developed to mark this special occasion

The MAX-1 is based on all our experience. It is our favorite for a variety of applications. Whether record players, streamers, amplifiers or smaller loudspeakers, the effect is immediately noticeable. The combination of three damping levels, different materials and damping rings achieves a high level of resonance dissipation. This function is the prerequisite for increased bass precision, as well as an open and clearly structured sound image. The MAX-1 is also very suitable for rather light devices, as it enables better coupling.

MAX-1

The optimized design with three damping levels, two balls and various materials achieves a high level of resonance dissipation without allowing vibrations from the ground to reach the device. A significantly better coupling and the resonance-optimized design make the MAX-1 one of the best device feet, we are certain of that.

LSP-1 and LSP-2

New in 2022
The LSP absorbers have reached series production readiness

Finally we can present the LSP absorbers. The LSP are the next step towards perfect reproduction. The internal damping has been significantly increased without disturbing the energy flow. This makes the LSP even more independent of the underground.

LSP is the acronym for Loudspeaker. This is where the LSP can show its full strength. Vibrations can be absorbed very well and reduced in the absorber. LSPs are also the right choice under a rack.

Alto-Extremo stands for flexibility. This also applies to the LSP. Under hi-fi equipment, the LSPs are also a very good choice, as they provide very good reproduction.

The LSP absorbers stand for a balanced, stable sound image. The music can flow, the focus increases. Our top product for many applications in the non-magnetic sector.

LSP-1

The choice of material and damping is crucial. The LSP-1 uses a stainless steel ball, which has proven to be ideal for dissipating vibrations. In combination with the damping rings and different materials, a very good and broadband choice. The resonance deflector on the ball support optimises the LSP-1. The LSP-1 is the smaller version of the LSP-2 and both are very similar. The LSP-2 can absorb even more energy and therefore has a slightly stronger effect.

LSP-2

The LSP-2 is the larger version of the LSP-1. A large bronze ball is used here to optimise the energy flow. The LSP-2 has a high internal damping and can therefore absorb a lot of energy. The resonance deflector on the ball support optimises the LSP-2. Attention is paid to the energy flow so that the sound does not become dull or unbalanced.

A perfect balance between coupling and decoupling!

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)

For the products Classic 2, Exact 1, Exact 2, MAX 1, LSP 1, LSP 2, SoN 1, SoN 2, a separate GPSR‑compliant product label is available.
