! 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. Two cases are
possible depending on the impedance load connected to the LA4 / LA4X (8 Ω for a single 8XTi enclosure, 4 Ω for two
8XTi enclosures in parallel):

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