To ensure both high performance and safety, L-ACOUSTICS
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.
IMPORTANT
The following table provides information regarding the recommended wire cross-section versus length:

According to the calculation in Table 1, a DO25/DOSUB-LA8 cable combination can be used to power one SB28 (4Ω
load) with a damping factor still greater than 20.
