By forming the conductors into a tube-like shape with a hollow centre, current densities at higher frequencies are maintained because the electric field which contributes towards the skin effect acts towards the centre of the conductor from where the conductive material has been removed.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eX-Tube™ technology first came to prominence in 2005 with the launch of the world renowned Silver Anniversary XT, the most highly regarded mid-range cable in the world, winning the What Hi-Fi Product of the Year three years in a row. These design principles also grace the multiple award winning XT40 speaker cable and XT25.\u003cbr\u003e\u003cbr\u003eAs frequency increases, electrons flow more and more towards the periphery of a conductor so that if the frequency is high enough only a very thin layer (or skin) on the outside of the conductor is used. This “skin depth” varies for different materials at a fixed frequency and in copper it means that if a conductor has larger than 0.66 mm² cross-sectional area not all of that area is available for an analogue music signal to use. In SAXT the “skin effect” problem was effectively eliminated by the use of X-Tube™ Technology which works by placing all of the conducting material around a central hollow insulating rod. However, for a.c. signals, changing magnetic fields generated by the flow of current set up eddy currents in nearby conductors which force current to flow only in areas furthest away from conductors carrying current in the same direction and vice versa.\u003c\/p\u003e\n\u003cdiv class=\"additionalawards\" data-mce-fragment=\"1\"\u003e\n\u003ch2 class=\"awards\" data-mce-fragment=\"1\"\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"col2\"\u003eAt low frequencies both X-Tube\u003csup\u003eTM\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eand conventional stranded\/solid core speaker cables convey signals in a linear way.
