van den Hul The TWIN (halogen free) per metre

In consumer applications The TWIN for instance is perfectly suited to upgrade the low-grade speaker wiring of mini-sets, external computer speakers and other low to mid-priced Hi-Fi systems where it yields noticeable sound improvements.

The Twin features high mechanical flexibility and is made of quality materials:
The Twin’s multistrand high purity Oxygen Free Copper (OFC) conductors provide clear and accurate signal transfer from low bass to high treble and its environmentally friendly, halogen free, HULLIFLEX ® 4 jacket provides excellent protection against external mechanical and chemical influences, thus ensuring a very long life.

The TWIN’s two conductors furthermore have different insulator shapes: one is round and the other has two edges with type printing on the flat surface: the most simple polarity finder you can think of.
