Please provide your email address and we will remind you when "QED XT25 Bi-Wire Speaker Cable - Price Per Metre" is back in stock.
To order bare speaker cables, select the length you require and 'Add to Basket', price is per metre of cable. Please note: All speaker cables are supplied in one continuous length unless ordering with terminations. To add termination options please use the tool above. Select your required 'Amplifier Termination' & 'Speaker Termination' plugs, then select your required length and quantity. Finally 'Add to Basket' and the total price will be calculated.

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 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.
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 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 of that area is available for an analogue music signal to use.
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 very upper frequency range, sometimes preceded by response peaking.
