The cable I use for home theater. It finally solves my problem, but when the projector and a player device (notebook) behind, the sound is due to arrive in front. Previously always dangled with the old sound system a normal audio cable across the room - inconvenient and uncomfortable. The purchased this Edifier C2XD 2.1 system I can now without the risk of ground loops etc. clean hide a 10m cable in the space around door frames, baseboards, etc. in cable channels and enjoy the clear sound that give the source and playback device. Despite the fairly thick diameter it is very flexible and can be (of course, with sufficient radius) still embarrassed closely.
