Atlas Equator Achromatic X 1 RCA to 1 RCA Subwoofer Cable
The Equator Achromatic X Sub is engineered to deliver clean, accurate bass response for both audio and home cinema systems. Today’s subwoofers require fast, precise low-frequency performance without the distractions of interference or unwanted noise. This cable is designed to meet that demand, eliminating RF and EM interference while preventing low-level hum often introduced by conventional cables. Constructed with shielded, high-purity OCC (Ohno Continuous Casting) copper, the Equator Achromatic Sub ensures signal integrity for superior sound reproduction. The conductor is housed in a low-loss foamed PEF (Foamed Polyethylene) dielectric, which enhances clarity and provides exceptional resistance to interference. This makes it an ideal solution for medium-length runs of up to 7 meters, offering flexibility without compromising performance. Available in both 1:1 and 1:2 configurations, the cable integrates seamlessly into various system setups. The latest generation of Achromatic X RCA connectors complete the design, featuring a cold-weld, solder-free construction for maximum reliability and long-term durability. Whether for immersive home theater or precise music listening, the Equator Achromatic Sub ensures your subwoofer delivers the depth and detail your system was designed to achieve.The Equator Achromatic Sub is engineered to deliver clean, accurate bass response for both audio and home cinema systems.

Achromatic Plugs
Atlas’s expert electro-mechanical knowledge has led to the innovation of the next generation of RCA plugs. Known as the ‘Atlas Achromatic RCA plug’, Atlas has focused on improving both performance and appearance to create a higher performance starting point for their RCA cables as well as eliminating variability in performance. This has been achieved by refocusing on materials and the assembly processes.
Atlas has made 4 key changes with the Achromatic RCA plug. Firstly, the barrel of the Achromatic plug features a high stability ABS material. This is strong, stable and of superlative surface quality.
There is also an improvement to the Achromatic plug’s contact geometry, aiding the contact properties of the plug and the self-cleaning wiping action to ensure contacts are in optimal condition and to maximise signal transmission.
The third change Atlas made was around the rifling of the RCA pin. This improvement self-aligns the conductors during the cold weld processing, ensuring a superior stable connection.
Finally, there is a reduction in the overall mass of the RCA plug by 8% which has shown to improve signal transmission.
The above changes mean a solder-free, low mass, self-cleaning, recyclable RCA plug with a non-conductive body.
OCC Copper
The Ohno continuous casting method re-heats the extrusion as the molten copper is forced out of the mould and very slowly and gradually draws the grain or crystal down the conductor''s length, creating a ‘single crystal structure.’ Actually, because no copper is 100% pure, there will always be a few boundaries produced by impurities. The frequency of boundaries created are quite insignificant. A typical crystal in a copper conductor drawn to 0.3 mm diam. using the OCC process is 125.00 metres long! The benefits are obvious, with almost no crystal boundaries, the audio signal is no longer impeded down the copper wire and more information and detail is delivered faithfully to the receiving equipment.

PEF Dielectric
PVC (Poly Vinyl Chloride) is cheap to produce and, as such, is the most commonly used insulation in AV cables. However, PVC is the worst quality insulation a Hi-Fi or AV signal can encounter as its high loss causes a significant reduction in signal velocity. PVC is better suited to power cables and should be avoided in Hi-Fi and AV signal cables. Other dielectrics in common use are Polyethylene, Polypropylene and Polytetrafluoride Epoxy (better known as PTFE (Teflon™) or Teflon,) and the new and unique Atlas (PTFE). PEF (Foamed Polyethylene). The foaming process uses a blowing agent, of which there are two types. Atlas use the gas-foamed method which creates a more inert, consistent and higher quality product. The table below shows the properties of a selection of dielectrics. Though not used as a dielectric in Atlas' cables, PVC is included for comparison purposes.
