General presentation Cable QED Reference XT400

XT 400 is a silver-plated OFC copper speaker cable in an X-Tube™ construction, with a section of 4 mm2. XT 400 is the silver version of the famous X40, one of the most successful speaker cables produced by the British company QED.

The QED Reference range uses an extremely high-performance, low-density polyethylene dielectric. It allows the substantial reduction of signal losses due to the capacity of the cable.

The conductor used is multifilar, 99.999% OFC (oxygen-free copper), silver-plated. The XT400 has a useful section of 4 mm2, excellent for connecting high-power amplifiers to gourmet speakers, even at greater distances than usual.

XT400 uses the X-Tube™ technology, patented by QED, to combat the appearance of the skin effect. A cable with conventional construction is affected by the film effect. It is manifested by the propagation of the signal flow at different speeds on the surface of the conductor, especially at high frequencies. The signal flow tends to be faster at its surface and degrades as we get closer to its core. Thus, the effective area that drives the high frequencies is reduced by at least 25% compared to the area of ​​the section. Through the geometric arrangement of the cable in the form of layers of lite wrapped around a dielectric core, X-Tube™ achieves an almost linear transmission, uniform over the entire area of ​​the section, without loss over the entire spectrum of the audio signal.

It is highly recommended to use QED Airloc™ terminals for these cables. Airloc™ terminals are a solution developed by QED and allow a perfect contact between the cable conductors and the plug body, contact made by crimping. The contact is a cold weld between the two materials, without air remaining between the conductors, without the risk of oxidizing over time, ideal for contact resistance and optimal signal transfer.
