QED XT40i Jumper Cables (2 Pair) สำหรับลำโพง 2 ตัว + QED’s AIRLOC FORTE metal spade plugs

QED XT40i เป็นสายที่พัฒนามาแทนที่และให้คุณภาพเสียงที่ดีขึ้นจาก QED XT40 เดิม

XT40 celebrates QEDs 40 years of award winning british heritage. Winner of Best Speaker Cable at the 2014 What Hi-Fi? Awards.

Acclaimed by What HI-FI? Magazine; this Five Star award winning pure copper loudspeaker cable boasts QEDs advanced X-TubeTM technology and a massive 4mm2 cross sectional area. This results in a cable that delivers clear sonic advantages over conventional cable designs by maintaining a flat frequency response within the audio band. We are so confident about the performance of the new XT40, we urge enthusiasts to audition and compare it, not only to their favourite cable but also to alternative models at any price.

Large Cross-Sectional Area
The 4mm2 cross sectional area means XT40 exhibits very low resistance, allowing amplifiers to exert outstanding control over the speakers they are driving. In addition, its large cross sectional area makes it suitable for long cable runs.

QED X-Tube Signal Diagram
X-Tube Technology
At low frequencies both X-Tube and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cables fail to conduct uniformly across the entire conductor area.

In standard speaker cables at high frequencies current flow is highest at the periphery with rapidly deteriorating current density towards the centre of the conductor.

The effect of this is to reduce the actual cross sectional area of the cable at 15kHz to less than 75% of that at low frequencies. This results in higher distortion and compromises the performance of the cable.

X-TubeTM with polycore technology exhibits much lower self-inductance and is therefore less affected by this problem. The polycore technology reduces loop inductance to levels only achievable using more costly and difficult to terminate cables.

The result is more high frequency detail, less distortion and greater performance.

QED’s AIRLOC FORTE metal spade plugs deliver a superior performance.
