C-screen speaker cable Prices from £5.00 (UK RRP) C-screen is a shielded speaker cable aimed at both audio and home cinema systems. It joins the award-winning line up of Chord Company shielded speaker cables, including the acclaimed Clearway and the high-performance Signature Reference. Our design objective was to produce a cable discreet enough for easy installation, with all the performance benefits that shielding can bring. C-screen is just 7mm in diameter and flexible enough to route around corners with ease. It’s finished with a white outer jacket which protects the shielding and makes it virtually invisible against white skirting boards.
