REL Bassline Blue Subwoofer Cable

 The special and unique characteristics of REL’s filter board are known only to REL engineers and within this circuit lies the key to designing cables optimised for REL Sub Bass Systems. Bassline Blue is a sensibly-dimensioned cable, well-constructed so that it will improve the overall sound of EVERY aspect of the host system’s performance.

As with ANY REL product—the improvement extends well beyond the obvious bass region. The greatest area of improvement lies in the manner in which the entire soundstage is illuminated. This is a quality quite different from brightness. Illumination acts to bring light into the stage and renders contrast and clarity as well as dynamic shadings much more evident.

Exceptional Materials – The Best Signal Transfer Requires Natural Drawn Copper: Beyond optimising the geometry of the internal lay of the cable, REL also employ copper that exceeds industry practices and is of a quality and type generally specified for military specification and high speed telecommunication applications. REL BLUE is constructed of slow-drawn, high purity copper, drawn in a nitrogen bath to minimise impurities on the surface of the wire. Each individual conductor is coated in a Teflon film immediately upon leaving the extrusion die to ensure that impurities cannot impinge on the cable while awaiting further processing. This technique produces a sound that is exceptionally pure and natural which we term Natural Drawn wire.

BLUE is hand constructed at REL’s California facility using cable produced exclusively to REL’s specification by a North American OEM wire and cable house. Construction is quite labor intensive and can require up to one hour per cable. REL use pure silver solder for all connections which ensures not just high quality sound, but also as the cable ages and oxidation sets in sonic degradation should be nil due to the conductive properties of pure silver.

The Connectors

REL employ Swiss-made Neutrik SpeakOn connectors at the input to the REL sub bass system. In over 100,000 RELs in use the world over, this connector has proven itself reliable, neutral and a mechanically ideal connector for REL’s renowned High Level Input circuitry. BLUE also features high quality spade lugs coated in gold to minimise oxidation. Should your amplifier require a bare wire connection, this is easily accommodated by manually re-terminating the individual red, black and yellow leads.

Greater Clarity

REL Acoustics Bassline BLUE will generate a noticeable improvement in every REL sub bass system. BLUE cable is the result of carefully balancing inductance, capacitance and resistance in such a way that greater clarity, speed and dynamics are ideally preserved. Some aftermarket cables claim to improve performance, but in our experience, the result is often a narrowly defined improvement with performance losses elsewhere. Because REL designs and develops their own proprietary input, filter and protection circuits, they have been able to balance ALL the parameters of BLUE™ to improve the total REL sonic package

The Challenge

Try this challenge: Leave the original REL cable connected and hook-up your new Bassline Blue to the speaker terminals of the main amplifier. Carefully dial-in the REL around Bassline Blue and allow the cable to break-in whilst playing for a few hours. Now, quickly switch back to the standard cable and the improvements Bassline Blue provides will be shocking. The standard cable sounds musical, but the stage will appear darkened, much like a theatrical stage in which the working lights have been extinguished. Switching back to Bassline Blue immediately results in the music being properly illuminated again.
