The LS-4005 AIR high-end speaker cable offers audiophile enthusiasts a unique sound experience. In the new Referenz LS-4005 AIR loudspeaker cable we have taken the outstanding properties of its predecessor the LS-4004 AIR and developed them even further. The point-to-point Air Helix design now enables the AIR Helix architecture to be used from plug to plug and not just between the sleeves. The 360° BFA bananas and spade lugs are a further innovation developed in-house for easy and convenient connection to the terminals. These and other technical refinements turn the already exceptional AIR cables into true masterpieces.
BFA Banana & Spade 360°
Movement across three axes make the 360-degree BFA and spade connectors really easy to connect and disconnect. Difficult set-up operations that put a strain on both cables and devices are a thing of the past. The connectors can easily be attached to terminals from a wide range of manufacturers. No awkward bending is necessary avoiding damage to surfaces and potential contact resistance. Set-up is fast and problem-free. The attractively designed connectors are the perfect complement to the outstanding sound.
Handmade
Each cable is handcrafted with the utmost care. Our extensive know-how and the qualifications of our team enable us to manufacture the complex cables in a customized manner. Apart from the finest of materials our most important resource is the manual dexterity of our cable assemblers. In assembling our outstanding cables they demonstrate meticulousness composure and dedication.
Rigorous quality control
We manufacture in accordance with the highest standards. Rigorous quality control is carried out before during and subsequent to assembly. We verify the tolerances of ever individual component. At every stage of manufacturing we check the configuration and electrics for short-circuits. We also conduct functional and mechanical testing. No product leaves our manufacturing unit without a final quality check.
