Element Achromatic RCA Subwoofer 1:2 by Atlas Cables is an excellent subwoofer connection cable with a dynamic, powerful but controlled sound. Available in 1:1 and 1:2 configurations, with this 1:2 version using OFC conductors with a screened 4-core construction.

Based on the multi-award winning Element Achromatic RCA Interconnect, this dedicated Subwoofer version provides excellent immunity to interference and noise, making it ideally suited to multi-source installations and the longer cable runs typically necessitated by optimum sub-woofer placement.

The cable utilises high purity OCC conductors with in a twisted configuration with cross-linked Polyethylene dielectric (insulation) for excellent immunity to external RFI (Radio Frequency Interference) and EMI (Electro Magnetic Interference), which can increase background noise levels and effectively decrease the dynamic range of your hifi or home theatre system.

The Atlas Element range includes other analogue interconnects, complementary USB & digital interconnects and speaker cables.
