RapcoHorizon SP4 Speaker Cable With Neutrik NL4FX Connectors | 6 ft

The RapcoHorizon SP4 series is designed for audio engineers and production crews who need dependable high-current speaker cable for demanding live sound environments. With four-conductor 13 gauge wire, the SP4 handles heavy power applications where undersized cable creates heat buildup or signal loss — making it a practical choice for main PA systems, subwoofer runs, and installed loudspeaker arrays.

Neutrik NL4FX Speakon connectors provide the industry-standard locking connection found on professional amplifiers and powered cabinets. This is a direct-connection cable for setups requiring NL4 terminations; engineers running single-channel NL2 configurations should reference the RapcoHorizon H series. The black matte PVC jacket is flexible enough for repeated coiling on touring rigs while holding up to the mechanical stress of permanent installations.

Available across multiple lengths to suit both short amp-to-cabinet connections and longer stage runs, the SP4 series gives integrators and touring engineers a consistent, professional-grade cable that covers the full range of amplified speaker wiring without compromise.
