Description

With the QED Reference XT25 Speaker Cable, QED tackles the proximity effect by combining Aircore and X-Tube Technologies. It incorporates two separate conductor bundles into a single, convenient X-Quad type geometry and presents a much more enjoyable rendition of the overall musical performance.

Very Low DC Resistance

At QED, we recognise that low DC resistance of the loudspeaker cable is of paramount importance for high-fidelity signal transfer. This is because the speaker presents a frequency-dependent load to the amplifier, of which the cable forms a variable proportion.

If the XT25 speaker cable resistance is too large, then the loudspeaker’s frequency response characteristics will change audibly, which the amplifierโ€™s negative feedback loop cannot correct.

Very Low Inductance

Cable inductance is a prime cause of high-frequency attenuation and phase shift in loudspeaker cables. High inductance causes cable impedance to rise with frequency, reducing output in the upper-frequency range, sometimes preceded by response peaking.

Low-Loss Dielectric

It is not generally appreciated that electrical signals, moving at or near the speed of light in a circuit, do so via the medium of electromagnetic (EM) waveforms, which exist not only within the copper conductors themselves but also within the XT25 speaker cable dielectric which insulates one from another.

The movement of electrons around the circuit merely facilitates generation of the EM waveform, as their drift velocity, measuring only a few centimetres per second, is much slower than the speed of light.

X-Tube Technology

As 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 Reference XT25 cable 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 mm 2 cross-sectional area, not all that area is available for an analogue music signal to use.
