SKU: 121453 Category:

Two pairs of QED XTC X-Tube Speakers Jumper Cables (Set for 2 Speakers).

2 Pairs of 20cm SPEAKER JUMPER Cables Terminated of one end 4x high quality 24 Gold-plated AIRLOC Banana plugs, other end 4x high quality 24 Gold-plated Spade connectors.Cables are 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.

To overcome the common problems associated with conventional speaker cable geometries – high capacitance and high inductance – QED speaker cables incorporate proprietary technologies such as QED X-Tubetm and QED Aircoretm. However, the one downside of these technological advances is the time it takes to terminate the cables. Because, to perform at their very best, they require a precise termination process.” But this is a problem no longer.  XTC utilizes the same  technology as Silver Anniversary X-Tube but with the removal of the silver plating and extra wide conductor spacing it aims at a warmer and rounder sound compared to its more expensive sibling.

HIGH PERFORMANCE LOW DENSITY POLYETHYLENE DIELECTRICCuts down on the amount of audio signal energy lost due to cable capacitance


At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTMretains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-TubeTMdelivers greater fidelity across the audio spectrum which would otherwise be lost in ordinary cables.


Provides a low resistance path for the audio signal
This unique tubular conductor geometry also provides lower flux density within the conductors, which gives improved transparency to the sound.

Hi. 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.
