About the Bassline Blue
REL Acoustics Bassline Blue is a purpose-built high-level connection cable for REL powered subwoofers. It connects a REL subwoofer’s Neutrik SpeakOn high-level input to the loudspeaker outputs of an amplifier, allowing the subwoofer to receive the same full-range signal as the main speakers. It uses REL’s Natural Drawn high-purity copper conductors, Teflon insulation, pure-silver soldered terminations, and a proprietary impedance-matched filter board. Standard versions terminate in a Swiss-made Neutrik SpeakOn NL4FC plug at the subwoofer end and three gold-plated spade lugs at the amplifier end; a Naim-compatible version is also offered with stackable banana-plug termination. It is compatible with REL models using a high-level SpeakOn input, but not REL Serie HT models, which use low-level/LFE connection only.
