For items not in stock, a direct stock check isn’t possible while you order. We check availability immediately afterwards and inform you without delay.

How to read the delivery time: The colour of the delivery van icon on the item matches the colour of the dot in the table.

Wie viele Coupler enthält ein Set?

Ein Set besteht aus drei Bamboo Couplern. Drei Kontaktpunkte reichen aus, um eine Komponente stabil und kippelfrei aufzustellen — anders als bei vier Füßen entsteht auf leicht unebenen Flächen kein Wackeln.

Warum ausgerechnet Bambus?

Der Coupler besteht aus vielen dünnen, kreuzweise verleimten Bambusstreifen ohne durchgehende Faserrichtung. Diese bewusst „chaotische" Struktur erschwert es Resonanzen, sich frei auszubreiten — die Schwingungsenergie wird an den zahllosen inneren Materialübergängen gebrochen und gestreut, statt wie in homogenem MDF oder Metall ungehindert weitergeleitet zu werden.

Wie stelle ich die verschiedenen Höhen ein?

Jeder Block misst 20 × 30 × 45 mm. Je nachdem, auf welche seiner Flächen er gestellt wird, ergeben sich drei Aufbauhöhen von 20, 30 oder 45 mm. So lässt sich die Höhe an den verfügbaren Platz anpassen oder gezielt für mehr Luftzirkulation unter dem Gerät nutzen.

Wie viel Gewicht tragen die Coupler?

Jeder einzelne Coupler ist für bis zu 100 kg ausgelegt. Ein Set aus drei Blöcken trägt damit auch schwere Vollverstärker, Endstufen oder massive Quellgeräte problemlos.

Verändern die Coupler den Klangcharakter meiner Anlage?

Nein — und genau das ist ihr Vorteil. Klassische Metallspikes koppeln effektiv, betonen dabei aber oft den Hochtonbereich und verschieben die tonale Balance. Der Bambus arbeitet neutraler: Er beruhigt das Klangbild und schafft mehr Ordnung, ohne der Komponente eine eigene klangliche Signatur aufzuprägen.

Wo platziere ich die Coupler am besten?

Die drei Blöcke werden unterhalb oder anstelle der werkseitigen Gerätefüße positioniert — idealerweise im stabilen Dreipunkt-Kontakt. Auf diese Weise umgeht man gezielt die oft mittelmäßigen Gummi- oder Kunststofffüße vieler Elektronikgeräte und stellt einen sauberen mechanischen Übergang zur Stellfläche her.

Kann ich die Coupler mit meinem vorhandenen Rack kombinieren?

Ja. Die Blöcke lassen sich auf jeder Oberfläche einsetzen und ergänzen vorhandene Racks, Basen oder Isolationssysteme. Blue Horizon liefert dieselben Coupler übrigens serienmäßig mit seinem Professional Rack System aus — ein Hinweis darauf, dass sie auch im Zusammenspiel mit hochwertigen Aufstellungslösungen ihren Zweck erfüllen.

Bamboo Coupler - Absorber - bluehorizon

Blue Horizon's Spike Shoe Extreme is the ultimate tool for eliminating resonance energy. As a high mass multi-resonance diffuser, it dissipates energy quickly through minimal point contact. The main purpose of the design is to channel resonance energy in the most effective and direct way by incorporating proper design philosophies in combination with material usage.
The Spike Shoe Extreme works with two systems in parallel. The first system eliminates all cabinet or speaker resonances quickly and efficiently using a 3 simplex concept. The vibrations are then neutralized within the unit through the use of a unique chaotic compound consisting of materials at opposite ends of the elasticity spectrum. This eliminates and cancels resonance over a wider range of frequencies. Through this unique process, the Spike Shoe Extreme has no tonal signature or characteristic, but simply expands the soundstage with more air and space. Microdynamics are also improved and the lower bass range is made more precise.

The outer shell of the Spike Shoe Extreme is precision machined from solid stainless steel, known for its high tensile strength, durability and corrosion resistance. Its three-dimensional shape is designed to respond to all vibrations like an inverted bell and has a very neutral and short resonance time.

The Spike Shoe Extreme is sold in sets of 4, each with a point loading of over 100 kg. They can be used with all speaker systems as well as under spiked components.

Blue Horizon's Spike Shoe Extreme is distinguished by several unique features. One of them is that the milled stainless steel outer shell of each Spike Shoe Extreme allows for point loading of over 100 kg. In addition, the proprietary blend of all parts used consists of materials at opposite ends of the elasticity spectrum. These different resonant frequencies ensure that resonance is damped evenly across the audio band, rather than just causing a tonal shift.
The improved coupling and effective resonance control provide clearly audible benefits. The Spike Shoe Extreme expands the soundstage, improving definition in the bass and up into the treble range. The soundstage opens up and microdynamics are expanded, resulting in an overall improved soundstage.

Hardened ball bearings and chaotic Resonance Deadening Compound (RDC) on the inside
