Despite their bulk, the cables are flexible due to use of convoluted Teflon tubing. In the case of speaker cables, it is much more difficult to greatly reduce audio band skin effect because of the need to have high conductivity metal with large cross-sectional area for low total resistance. This low a resistance is needed for good bass control and extension due to the high drive currents and corresponding maximal cable voltage drops involved. It was found that this simple design requirement was by far the most important for the speaker cable. The many other parameters commonly used in speaker cable design were found to be either relatively unimportant in the ribbon cable or not applicable at audio frequencies.
Examples are extreme metal purity, dielectric material and characteristic impedance.
The resulting speaker cable is in the form of two separate five-inch wide flat cables for each speaker. For best performance the two separate flat cables driving a speaker should be laid side by side where possible rather than on top of each other. The physical appearance of the Magnan Signature Speaker Cable is high-tech with a glossy black nylon woven jacket.
