PureLink Speaker Cable Box Cable OFC 2 x 4.00 mm² 0.20 mm 10.0 m Pure Copper Cable for HiFi Speaker Boxes Subwoofer, Audio Cable with Polarity Marking, Black

Description

From the manufacturer Speaker cable black - reference class with 99.9% OFC solid copper With the PureLink OFC speaker cables, you can be sure that the cables are made of 99.99% OFC copper, very good conductive or transmission units and have also been processed to high quality standards in Germany. The OFC copper conductors impress with a high degree of flexibility and low line resistance. What is the difference between diameter and cross section? The diameter in mm is a length measure, the cross section in mm² is a surface dimension. Since the PureLink speaker cables are made of individual copper strands, the cross section is indicated here as an area, which cannot be equated with the diameter and is therefore always smaller. IMPORTANT The specification 0.20 mm strand does not mean that the geometrically measurable cross section is 0.20 mm. Here the nominal cross section is given, which refers to the electrically effective conductivity and the ohmic resistance of the cable at 20°C. Different cable cross sections depending on your requirements In general: The longer the speaker cable, the greater the power loss, which is only noticeable in the loudness of the signal at the speaker end. Since a loss of performance can be counteracted with an increase in the cable cross-section, it is useful to use cables with different cross sections (e.g. larger cross-section in the rear speakers of a surround installation). With a length of 10 m, the performance losses are approximately 0.75 mm². Cable: 5.25% 1.5 mm². Cable: 3.13% 2.5 mm². Cable: 1.63% 4 mm². Cable: 1.00% A pure copper cable - Made in Germany The great advantages of pure OFC (oxygen free copper) copper cables are their excellent electrical conduction properties as well as the low conduction resistance. Often speaker cables are output as "pure" copper cables, although they only have wafer-thin copper coating. This mainly applies to cables designated as "CCA copper" (aluminium core with thin copper coating) or "CCS copper" (steel cable with thin copper coating). These cables have far worse transmission properties than OFC copper cables! Suitable for permanent installation inside buildings This cable has a marking and a corresponding declaration of performance according to the EU Building PVO No. 305/2011. According to standard EN 50575:2014 + A1:2016, the cable has the fire behaviour Eca. Review: OFC - Very good quality ofc wire will buy again. Review: Kabel prima kwaliteit - Kabel is soepel en niet te dunne draad wat samen een draad is
