Synergistic Research Foundation XL REL Spec Subwoofer Cable

Synergistic Research Foundation XL REL Spec Subwoofer Cable

Foundation XL REL Spec Subwoofer Cable is built specifically for REL subwoofers' proprietary Speakon connection, bringing the core technologies developed for Synergistic Research's flagship SRX XL cable line to REL's High Level input. It uses 6x pure silver Air Strings in an air (sealed) dielectric, 33% more than Foundation SX, for tighter, more textured bass. Every cable uses SRX XL Matrix Shielding with Graphene and is treated with SRX XL High Voltage Conditioning, bringing Foundation XL's voicing closer to the flagship SRX XL line. Included Gold and Purple Carbon Tuning Discs let you voice the cable to your system, or run it clean. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you connect your REL subwoofer with the correct cable and length.
