Description

Melodika Sky Blue SBSW60

The Sky Blue series represents a step toward mature hi-fi and a clear upgrade over the Purple series. The SBSW is an RCA-to-RCA subwoofer cable designed to provide a stable connection between a Sub Out/LFE output and a subwoofer. It was specifically engineered to eliminate interference, which frequently occurs when transmitting low frequencies over longer distances. The cable offers enhanced insulation, new connectors with PTFE inserts, more effective shielding, and more stable signal transmission.

Melodika SBSW

Dual Shielding

SBSW utilizes dense dual shielding to limit the penetration of electromagnetic (EMI) and radio frequency (RFI) interference into the signal path. The first layer consists of Mylar foil, while the second is a copper braid with a minimum 95 percent coverage, ensuring effective attenuation of external interference.

In practice, the copper braid, as a low resistance layer, effectively suppresses lower frequency interference and provides a stable path to ground for induced noise. The Mylar foil, thanks to its full coverage, complements this by restricting higher frequency interference. Together, these layers form a broadband protective barrier that reduces the risk of unwanted noise entering the signal, particularly in electrically noisy environments.

Melodika SBSW

Twisted Cores geometry

SBSW is based on the proven Twisted Cores design, in which two conductors - each with a thickness of 0.35mm² - are twisted together with an additional cotton dielectric to prevent crosstalk and enhance signal integrity. 

Melodika SBSW

RCA plugs with PTFE insulation

The cable is terminated with new 24k gold-plated RCA plugs with PTFE insulation. Their signature notches improve fit and connection stability. The plugs are soldered using high-quality silver solder, and the specific assembly method ensures proper cable directionality in accordance with the markings.

Construction:

  • 4N OFC copper conductors (99.99%)
  • New RCA plugs with PTFE insulation and distinctive notches for improved socket grip
  • Dual Shielding: A combination of Mylar foil and a minimum 95% coverage braid
  • Precision soldered joints using high-quality silver solder
  • Additional dielectric in the form of cotton fibers
  • Balanced symmetrical design featuring twin 0.35mm² conductors
  • PE internal insulation and a rugged PVC outer jacket
  • The jacket is resistant to UV, saltwater, ozone, and alcohol; it offers exceptional impact resistance and mechanical energy absorption across a wide temperature range, alongside superior abrasion resistance

Functionality

Subwoofer cables are often ignored by novice users. As a result, it very often results in a hum of the subwoofer. Buying the lowest quality subwoofer cables is an obvious mistake. There are several arguments for this. First, we are dealing with an unbalanced analog signal that is the easiest to distort. Secondly, it is usually sent further 5, 10 or even 15 meters. Third, these types of cables are often subject to physical damage. Is it when laying behind the slats or loose on the floor.

Therefore, when choosing a subwoofer cable, it is important to shield the subwoofer so that it does not rustle, the quality of the plugs and the insulation - preferably double, which will protect the cable from moisture, assembly and stepping on.

Why copper purity is so important?

The signal which is running through the guide should encounter on its way as little obstructions as possible. In case of low purity copper the amount of impurities which must be bypass is large. Then we can say that the signal has to go through a real slalom. In the purified copper, electrons run straight to the goal, so the sound is not distorted. Moreover, there is another argument. Copper impurities include oxygen atoms. They cause oxidation. Produced copper oxide which is much weaker conductor than the proper copper. In this way the conductivity deteriorates which obviously affects the sound.

Shielding:

Shielding is something like a barrier to electromagnetic interference.

If the guide has more layers of shielding or the shielding is thicker, it's better.
