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. Below you can learn more about the outstanding technical features of this cable, the innovations in the 5th generation and the physical principles used in the AIR technology.
