QED, the specialist UK hi-fi and home cinema connectivity manufacturer, has declared that its renowned loudspeaker cables are now the 'World's easiest to terminate'. How? Because QED has already done the job for its consumers.
Jack Fox, QED's Brand Manager, stated:
"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."
"QED is pleased to introduce its new pre-terminated speaker cable range."
The new pre-terminated cables listed below, are available now from authorised stockists worldwide. They all come fitted with high quality 4mm plugs using QED's superior Airloctm cold weld system.
|QED Performance XTC x 2m Pair|
|QED Performance XTC x 3m Pair|
|QED Performance Ruby Anniversary Evolution x 2m Pair|
|QED Performance Ruby Anniversary Evolution x 3m Pair|
|QED Reference Silver Anniversary XT x 2m Pair|
|QED Reference Silver Anniversary XT x 3m Pair|
|QED Signature Revelation x 2m Pair|
|QED Signature Revelation x 3m Pair|
Important note: The introduction of pre-terminated cables has no effect on the availability of 'bare' (un-terminated) QED speaker cables. All bespoke lengths and requirements will continue to be available from QED authorised dealers and the QED custom cable service.
About: QED X-Tubetm, QED Aircoretm and QED AIRLOCtm PLUGS
At low frequencies both X-Tubetm and conventional stranded/solid core speaker cables convey signals in a linear way.
However, at high frequencies, the current flow in standard speaker cables 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.
At the same high frequencies, X-Tubetm retains a near-linear signal transfer because its 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 cables above 2.5mm2 cross sectional area utilize air core technology to obviate the skin effect by bundling several separately insulated smaller cores together to make up a larger CSA. If these conductors are arranged around a hollow central core of polyethylene the self inductance exhibited by the cable can be reduced to around half that predicted by calculation.
QED AIRLOCtm PLUGS
QED developed 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.
