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 length versus wire cross-section. Three cases are
possible depending on the impedance load connected to the LA8 (8
in parallel, 2.7 for three KARA):

According to the calculation in Table 2, one DO25 cable (4 mm², 25 m) can be used to power two KARA in parallel
(4 load) with a damping factor still greater than 20.
