XT25 is an OFC copper speaker cable, in an X-Tube™ construction, with a section of 2.5 mm2. Due to the minimal losses and the optimal electrical resistance, the watchword in the case of XT25 is neutrality, this cable will always reproduce the sound unchanged over the entire frequency spectrum.

QED XT25 cable
Premium technology for unforgettable auditions
The X-Tube technology that appeared in 2005, which brought many awards to our cables, is also present in the new XT25. As the frequency increases, the flow of electrons takes place towards the periphery of the conductor, so in the case of certain high frequency sounds, only the outside of the conductor is used. This problem is eliminated by the X-Tube technology by positioning all the conductors around a concentric core.
Minimum electrical resistance for maximum qualities
It is not generally appreciated that electrical signals traveling near the speed of light through a wire do so by means of electromagnetic (EM) waveforms that exist in the dielectric surrounding the conductors as well as inside the conductors. . The movement of electrons along the conductor facilitates the generation of the EM waveform, since the "rolling speed" is only a few centimeters per second. Therefore, it is important to ensure that the dielectric material used to insulate and protect the central conductors without significant losses. Dielectric losses are directly proportional to the "permittivity" of the material used, and since this is a measure of each material relative to that in a vacuum, it should be as close to unity as possible. Like its predecessors, the XT25 uses a specially formulated Low Density Polyethylene (LDPE) dielectric, which at 1.69 has the lowest relative permittivity practically available.
99.999% Copper without oxygen
Speaker cables must have a high carrying capacity. If the electrical resistance of the cable is too high, part of the musical signal will be lost, causing a negative effect on the fidelity of the sound you hear. To eliminate this, we minimize the resistance of the cables. That's why we use exclusively 99.999% oxygen-free copper.
