Oehlbach 110312 AIR BLUE 3
Oehlbach Air Blue 3 speaker cable in pure copper, fitted with high-end banana plugs, available in several lengths.
Description
The Air Blue 3 is a speaker cable from Oehlbach, designed to connect an amplifier to speakers while preserving audio signal quality. It is supplied ready-assembled with banana plugs, ready to use on most amplifier and speaker terminals.
The cable is built from pure copper strands, a material recognised for its good electrical conductivity, combined with a cross-section of 2 x 3 mm² that helps limit resistance over the length of the cable. The presence of a dielectric and a porous PVC sheath contributes to the electrical insulation of the conductor while maintaining a degree of cable flexibility.
The banana plugs fitted at each end are described as high-end, promoting stable contact and easy connection to the spring-clip or screw terminals of speakers and amplifiers.
This cable is aimed at hi-fi enthusiasts wishing to ensure a quality connection between their amplifier and speakers, in a standard home installation. It suits both a stereo setup and a system requiring several pairs of cables of the same quality.
The model is offered in several lengths, from 2 x 2 m to 2 x 5 m, allowing the choice to be adapted to the listening room configuration and the distance between the amplifier and the speakers.

What to check before buying used
On an already-assembled cable, particular attention should be paid to the banana plugs: check that they show no play or oxidation and that they insert firmly into the terminals. Inspect the PVC sheath along its full length for cracks, sharp bends or crush marks that could weaken the insulation. An electrical continuity check at both ends confirms that the copper has not suffered an internal break invisible to the eye.
