[QUOTE="Nick Hickman, post: 31642, member: 556"] Re: Does damping factor have any noticeable effect? Hi Richard, If you cut a slice through the cable, the cross-sectional area of a conductor is simply the area of copper exposed. In the UK at least, this is the fairly universal way in which cables are described. The units of area are square-millimetres, or [IMG]http://100dB.com/misc/mm2.png[/IMG], or mm^2. Cross-sectional area is sometimes abbreviated as CSA. Your cable is Van Damme "Blue series" speaker cable, two cores, each 4mm^2 cross-sectional area. The seller is calling it "4mm" cable as a shorthand. VDC, another seller, show the specs for the range of cables like this: [CENTER][IMG]http://100dB.com/misc/vandamme.png[/IMG][/CENTER] The "conductor stranding" bit means the cable has 227 strands of copper, each 0.15mm in diameter (and here the convention is that it [I]is[/I] the diameter that's stated!). Given that the area of a circle is given by Pi times the square of the radius (and the radius is half of the diameter), the overall conductor area is 227 * 3.1416 * (0.15/2) * (0.15/2), or 4.01 mm^2. The bottom line is that, for the lengths you're using, your cable is fine. Nick [/QUOTE]
