AirGap isolation/Anti-vibration

Audiophile AirGap isolation

‘AirGap’ isolation is a technique when Air is used to isolate a Power cord, Interconnect cable or a Loudspeaker cable. By insulating the cable we also isolate the cable from certain elements which affect performance. This technique is similar to double glazing. We use double glazing to insulate the interior of a house to keep it warm. By Insulating the interior we also isolate the house from external noise and vibration. If we use triple glazing the results are even better. Audio cable isolation is necessary to reduce the negative effects of external frequencies and vibrations – read more

Two meter Power cord

AirGap steps

The picture above shows a white power cord running from left to right. Over the power cord is a layer of black material (CanuFlex PE-HB). This material has a very fine ‘mesh’ and is used to trap the pockets of air.

The CanuFlex PE-HB is covered with a green sheathing material (DeRay-PBFSP). This material is slowly heated to a predetermined temperature. As the DeRay-PBSFB contracts, the air is trapped and forms an insulation around the cable.

The first layer of insulation is complete. If this process is repeated a second layer of insulation will be added. If this process is repeated, the third layer of insulation will be added around the cable.

The ‘AirGap’ isolation process makes an audio cable perform better. This is because the cable is isolated from external vibration and interference – read more

The Composition ~

The Perkune audiophile ‘AirGap’ insulation has over 720 pockets of Air per square inch of material. These pockets of Air are ‘trapped’ in the material which runs the entire length of the cable. 

Thousands of pockets of air

The example ~

The two-meter Power cord is an inexpensive upgrade and a good example to start with.

The Perkune audiophile power cord has a diameter of 9.0 mm.

After three levels of isolation, the power cord diameter increased from 9.0 mm to 15.0 mm.

This is an increase of 40% and gave an excellent result in cable performance.

The Power cord is still flexible and easy to work with.

The results of AirGap isolation

The first level ~ 17,280 pockets of ‘trapped’ Air.

The second level ~ 34,560 pockets of ‘trapped’ Air.

The third level ~ 51,840 pockets of ‘trapped’ Air.

These results are for a two-meter Power cord. 


Power cords – Tip to Tip

Power cord two meter

When this technique is used on the Power cord the isolation is taken to the inside of the plugs and termination screws ensuring the Ultimate connection and reducing the effects of mechanical and electrical vibration.

Interconnect cables – Tip to Tip

XLR connections

When this technique is applied to the interconnect cables, the Canuflex PE-HB is taken right into the connections. This is giving tip to tip coverage which ensures a perfect isolation from external interference and effects of mechanical and electrical vibration.

Loudspeaker cables – Tip to Tip

Antivibration connections

When this technique is applied to the loudspeaker cables, the Canuflex PE-HB is taken right over the connections. This is giving tip to tip coverage which ensures a perfect isolation from external interference and effects of mechanical and electrical vibration.


Anti-vibration collars

A good vibration isolator lowers the natural frequency of a system to below the excitation (or disturbing) frequency. Keeping these two frequencies “out-of-sync” greatly reduces vibration problems. A good vibration damper takes mechanical energy out of the system.

Properly-designed metal springs and rubber mounts can be good isolators but have almost no damping capability. Oil dampers (dashpots) have good damping capability, but no isolation capability. Foam products can be good isolators but have limited life.

Our product can absorb over 50 percent of vibration energy and 0ver 80% of shock vibration over most of its temperature operating range at frequencies from 10 to 30,000 Hertz. It has a superior damping coefficient, over a very wide temperature range, compared to any other polymer. The operating temperature range is -20° to +160° Fahrenheit (-29° to 72° Celsius). Unlike fluid-based shock absorbers or foam products, our product absorbs shocks efficiently for millions of cycles which eliminates the need for metal springs to return the system to its equilibrium position after absorbing a shock.

Power cord collars, Interconnect collars, and Loudspeaker collars are currently under test and information will be released at the end of November ~


The ‘AirGap’ isolation process can be applied to any cable where isolation is required. The Anti-vibration collars are currently under test but indications of over 50% in vibration reduction and 80% reduction in shock vibration is realistic. The performance of the cables is greatly improved by using these techniques regardless of system price.

I have been testing for months and have excellent feedback from my colleagues and customers. The results inspired me to improve the range using the ‘AirGap’ isolation and Anti-vibration technique. A person is now able to hear more of the musical presentation than ever before, which in itself is inspiring!

    1. Hello Alan

      It is actually Anti-Vibration that I am working on in this project. I am testing several
      different types of material for their Anti-vibration properties. When I find the material
      that I am happy with (which does not have an exorbitant price) I will add it to my range of
      cables because this is something that is overlooked in the audio world. In fact, there are
      only a few companies that have addressed this issue and able to offer a product but at a very
      inflated price.
      My plan to have something by the end of November /beginning of December and it will be worth
      waiting for!

      best regards
