QED Silver Anniversary XT Bi-Wire Speaker Cable 5.0m Pair

Here we have a pair of Silver Anniversary XT Bi-Wire loudspeaker cables from one of the first major companies to specialise in the production of Hi-Fi cables – QED. They are five metres in length, unterminated and come in good condition.
QED Say….
In a single wired system unwanted mechanical and electrical resonances appear as distortion at both sets of speaker terminals. Due to the impedance of the cables these distortions will not be entirely cancelled by the amplifier, instead modulating between the two sections of the speaker system, degrading sound quality. With bi-wiring this interaction is minimised as signal distortion is “seen” at the amplifier’s output where it can be more effectively cancelled. The purpose of bi-wiring is to present a clean signal at both the bass and treble speaker terminals.
Silver Anniversary Bi-Wire elevates our multi-award-winning design to a dazzling new level. This exciting cable incorporates the same materials technology as Silver Anniversary, but features separate dedicated conductors for both bass and treble. These are arranged in an enhanced geometry to give sparkling gains in clarity, realism and dynamic impact. A cable for those who want to experience the very best performance from their Bi-Wire equipped Hi-Fi and Home Theatre systems. Flat double figure 8 construction- 4 x 2.50mm2 conductors.
