4 x 20cm (Set for 2 Speakers) QED Reference X-TUBE XT-400 Speakers Jumper Cable.
2 Pairs of SPEAKERS JUMPER Cables Terminated of one end 4x high quality 24 Gold-plated AIRLOC 4mm Plugs, other end 4x high quality 24 Gold-plated Spade connectors, and all pressure crimped of professional crimping tool QED AIRLOC HIGH PERFORMANCE TERMINATION.
The ends finished with colour coded black & red heat shrinks.
AIRLOC a solder-free, airtight perfect fusion between the two metals of cable and plug. This ‘cold weld’ method allows the cable and plug to offer the optimum signal transfer and therefore, better sound quality. It also reduces contact resistance and ensures perfect long-term performance.
So what do I do with these jumper cables?
Well, almost all speakers come with standard grade copper jumpers (bare rails). For a quick and effective upgrade to your bi-wirable speakers simply remove the standard connectors bare rails and affix ours for instant Qed.
QED’S MULTI-AWARD WINNING XT400 SPEAKER CABLE, UTILISING X-TUBETM TECHNOLOGY
Silver-plated oxygen-free copper tubular conductor geometry. For use in the finest hi-fi and home theatre systems. This design delivers a massive cross-sectional area using X-TubeTMtechnology to eliminate the skin effect whilst maintaining a user friendly “figure of 8” geometry. This is QED’s ultimate affordable upgrade for high end systems.
At low frequencies both X-TubeTM 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.

Hi Dear. I wanted to add a few words from me.
Repeatedly tested my products and reaching for feedback from my clients and I’m certain that the results are better than with the original links and that bi-wiring there is unnecessary and expensive. All in all, my customers rate this as a very good value up-grade.
If you would like a different combination of spade to spade connectors, or banana to banana plugs , or different jumpers lengths, please contact us.Please have a look at our other items.Thanks for looking.
