In-akustik Reference LS-4005 AIR speaker cable

Description

In the new Reference LS-4005 AIR loudspeaker cable, In-akustik has 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.

Features:

“Point-to-point Air Helix” for authentic sound.
Air as the ultimate dielectric minimizes capacitance
Cross Link Super Speed waveguide for a balanced sound
XLR connectors can be adjusted by +/- 45 degrees
The RCA-SL connectors are pressure-grouted using a force of 1.5 tonnes for a precision fit

Variations in standard 3.0m lengths – other lengths to special order. (KEY: BFA 4mm Banana; SW Single Wire; SBW Single Bi-Wire)

Audio scrutiniser-in-chief Paul Miller has auditioned the In-akustik LS-4005 Air speaker cable in Hi Fi News’ July 25 issue. Awarding his top Editor’s Choice accolade, he says it’s “both lighter and more physically flexible than its 4cm diameter might suggest. Its sound, too, is writ large with air and atmosphere, and proves more than competitive even at this heady price. If you’re after a big sound, the Referenz LS-4005 AIR pulls out all the stops.”
