The TUBULUS Libentus Subwoofer Cable is based on high quality silvered copper conductors. These solid core silver conductors are surrounded by mainly air, because (except for a vacuum) air is the best dielectric.

This air insulation is made possible by our tube construction, which can only be made by hand. The high quality silvered copper conductors are placed behind a very thick copper shielding.

The TUBULUS Libentus Subwoofer cable is available with high quality silvered RCA plugs or XLR plugs, which are soldered with silver containing solder.

TUBULUS Libentus Subwoofer cables are hand crafted with love, expertise and devotion with no excess decoration or luxury packaging and therefore true value for your money!

The use of solid core conductors eliminates the inherent problem with multi-stranded wire. As electrons travel along such a multi-stranded wire, there is nothing to keep them from “jumping” repeatedly from one strand to another. The main problem is the oxide film that covers the metal surface. When it jumps from one strand to another, the signal crosses two oxide boundaries and “jumps” across a thin air gap. This affects the signal passing through it by partially rectifying that signal and thus the musical signal. With multi-stranded silver wire this effect is less pronounced then with copper, since silver oxide is conductive.



  1. Alpha Audio

    The Libentus is a lively and neutral sounding interlink. Sound staging is deep and wide. Instrument placing is very good and the transparency is perfect. Sublow is very convincing and more importantly, also perfectly controlled. A nice, easy and very musical interlink which sounds much more expensive than it actually is.

    Original Review (Dutch)
    De Libentus is een levendige en neutraal klinkende interlink. Geluidsbeeld is diep en breed. Plaatsing is zeer goed en de transparantie is perfect. Sublaag wordt heel overtuigend weergegeven en belangrijker, de controle hiervan is eveneens perfect. Een fijne, gemakkelijke en zeer muzikale interlink die veel duurder klinkt dan dat deze in werkelijkheid is.
