Bassline BLUE™ is a high-performance high-level sub-bass cable custom-engineered by REL Acoustics to elevate the clarity, speed, and dynamic performance of REL sub-bass systems. Hand-constructed at REL's California facility, the cable utilizes slow-drawn Natural Drawn™ high-purity copper, processed in a nitrogen bath and insulated in a Teflon film immediately upon extrusion to eliminate surface impurities.

Carefully balancing inductance, capacitance, and resistance, Bassline BLUE™ preserves the integrity of REL's proprietary High Level Input circuitry. Terminators feature a Swiss-made Neutrik SpeakON connector on the subwoofer end and pure gold-coated spade lugs soldered with pure silver on the amplifier side for oxidation resistance and signal purity.

KEY FEATURES & CONSTRUCTION

• Natural Drawn™ Copper Conductors: Slow-drawn, high-purity copper produced in a nitrogen bath to prevent surface contamination and deliver a pure, uncolored sound.
• Immediate Teflon™ Insulation: Each conductor is coated in a Teflon film directly upon leaving the extrusion die, sealing out environmental impurities.
• Hand-Assembled Construction: Precision hand-built in California, requiring up to one hour of labor per individual cable.
• Pure Silver Solder Jointing: All termination connections utilize pure silver solder to eliminate long-term signal degradation caused by oxidation.
• Neutrik SpeakON & Gold Spade Termination: Uses Swiss-made Neutrik SpeakON input connectors and gold-plated spade lugs (which can be re-terminated for bare wire connections if required).
• Balanced Circuit Parameters: Specifically tuned by REL to balance inductance, capacitance, and resistance for total system synergy rather than isolated band improvements.
