2 x 2,5mm² speaker cable transparent – reference class with 99,9% OFC copper – 0,10mm braid – 100 meters
With the OFC speaker cables from Sentivus, you can be sure that the cables are made of 99.99% OFC copper, have very good conduction and transmission qualities and have also been processed according to high quality standards in Germany.
The OFC copper conductors can convince with a high flexibility and a low line resistance.
OFC – 99,9% pure copper, free of oxygen (Oxygen Free Copper)
A pure copper cable – Made in Germany
The great advantages of pure OFC (oxygen free copper) cables are their excellent electrical properties as well as the low line resistance.
Often, speaker cables are called “pure” copper cables, although they have only a very thin copper coating.
This mainly concerns the as “CCA copper” (Aluminum core with a thin copper coating) or “CCS copper” (Steel cable with a thin copper coating).
These cables have far worse transmission characteristics than OFC cables!
Different wire sizes, depending on requirements
In general, the longer the loudspeaker cable, the greater the loss of power, which is however only noticeable in the loudness of the signal at the loudspeaker end.
Since a power loss can be counteracted with an increase in the cable cross-section, it is useful to use cables with different wire sizes, depending on the cable length (for example, a larger cross-section for the rear speakers of a surround installation).
With a length of 10m, the power losses are approximately:
– 0,75mm² cable: 5,25%
– 1,5mm² cable 3,13%
– 2,5mm² cable 1,63%
– 4mm² cable 1,00%
This cable (2.5mm²) is available in the following lengths:
10m / 15m / 20m / 25m / 30m / 50m / 100m
Under SE-SP-011 you will find the same cables with white sheathing.
