recommends the exclusive use of
high-quality, fully insulated speaker cables made of stranded copper wire.
In order to preserve a high damping factor it is desirable to keep loudspeaker cables as short as
possible and with a gauge offering low resistance per unit length.
The following table provides information regarding the recommended length versus wire cross-section.

According to the calculation in Table 1, one SP25 cable (4 mm², 25 m) can be used to power one 12XTi (8 Ω load) with
a damping factor still greater than 20.
