The one specification on this shelf

Shielding. A subwoofer cable is the longest analogue run in a home cinema, carrying a low-level signal, and it almost always has to cross mains cabling on its way across the room. That is the recipe for interference, and shielding is what prevents it.

This listing states that the cable is shielded and that it is coaxial. It does not describe the construction — foil, braid, or both — which is the detail the better cables on this shelf publish.

The jacket

8 mm. Substantial for a single-ended RCA cable, and it usually implies a real screen underneath rather than a thin one.

The length

Three metres. Enough for a subwoofer on the same wall as the rack; frequently not enough for one placed where it sounds best. Subwoofer position is found by listening rather than by geometry, and the cable that only just reached the first position will not reach the second.

The habit worth more than any cable here

Cross mains cables at a right angle rather than running alongside them. It costs nothing and removes more hum than any upgrade on this shelf.
