Kimber Kable REL CU Subwoofer Cable
Best high-fidelity upgrade for dedicated subwoofer enthusiasts seeking cleaner bass performance.
Upgrade your REL subwoofer's performance with the Kimber Kable REL Cu cable. This premium cable is engineered to deliver superior sound quality, building upon Kimber's acclaimed Cu speaker cable. It features a specialized hex braid geometry to effectively combat RF and EMI interference, ensuring a cleaner signal. The cable utilizes dual 19 AWG Varistrand copper conductors per polarity, resulting in a net 16 AWG gauge for wider bandwidth and reduced noise. It includes advanced FEP dielectric, a low-temperature, high-pressure extrusion process, a protective braided nylon sleeve, and a Neutrik locking speakon connector for a secure, high-level connection to your subwoofer.

Know before you buy
The Neutrik Speakon connector is the industry standard for high-level subwoofer connections. It provides a secure, locking interface that ensures a reliable electrical connection and prevents accidental disconnection.
The hex braid geometry is designed to minimize the cable's susceptibility to radio frequency (RF) and electromagnetic interference (EMI). By reducing this external noise, the cable maintains a cleaner signal path for your subwoofer.
The 16 AWG gauge provides a low-resistance path for the signal, which helps maintain a wider bandwidth. The Varistrand construction uses varying conductor strand sizes to further refine the signal, resulting in a lower noise floor and more precise bass response.
Yes, the cable is available with different termination options for the amplifier end, including spades, banana plugs, or bare wire for soldering. This ensures compatibility with a wide range of amplifier output terminals.
FEP (Fluorinated Ethylene Propylene) is a high-performance insulating material that keeps the signal stable and protected. It is chosen for its excellent electrical properties, which help preserve the integrity of the audio signal from the amplifier to the subwoofer.
