Kimber Kable REL CU Subwoofer Cable

REL subwoofers utilize a unique high-level connection that draws the signal directly from your amplifier's speaker terminals. This cable is engineered to match the specific impedance and signal requirements of that connection, ensuring the subwoofer remains perfectly in phase and tonally matched with your main speakers.

The hex braid geometry is a signature Kimber Kable design that physically cancels out electromagnetic interference and radio frequency noise. By reducing this interference, the cable maintains a lower noise floor, which allows for cleaner, more precise bass reproduction.

This cable is purpose-built for the high-level input found on REL subwoofers using a Neutrik Speakon connector. While it may physically fit other devices with similar connectors, it is specifically optimized for the electrical characteristics of REL systems and may not provide the intended results with other brands.

Varistrand copper uses varying strand sizes within the conductor to minimize the internal resonances that can color the sound. This results in a more transparent signal transfer, ensuring that the low-end frequencies remain tight, dynamic, and free from distortion.

The 4.5-meter length is generally sufficient for most standard listening rooms where the subwoofer is placed near the front speakers. If your amplifier is located significantly further away from your subwoofer, you may need to ensure this length provides enough slack for clean cable management.

FEP (Fluorinated Ethylene Propylene) is a high-quality insulation material that maintains the integrity of the signal by minimizing dielectric absorption. This helps preserve the speed and transient response of the bass, preventing the signal from sounding sluggish or muddy.
