Recommendation for speaker cables
Recommendation for speaker cables
Cable quality and resistance
Only use high-quality fully insulated loudspeaker cables made of stranded copper wire.
Use cables with a gauge offering low resistance per unit length and keep the cables as short as possible.
It is good practice to keep loudspeaker cables short to ensure optimal system performance. L-Acoustics strongly
recommends using cables of similar type, length, and gauge to address symmetrical deployment of loudspeakers, such
as stereo systems, L-ISA frontal systems, or outfill systems.
For more information about cable effect on loudspeaker frequency response, refer to the publication
Demystifying the effects of loudspeaker cables on the L-Acoustics website, in Education> Scientific
resources> Scientific publications.
Refer to the following table for recommended cable length for uncompromised performance.

Use the more detailed L-Acoustics calculation tool to evaluate cable length and gauge based on the type and number
of loudspeakers connected. The calculation tool is available on our website:
