Appendix C: Recommendation For Speaker Cables - L-Acoustics A15i Series Owner's Manual

Recommendation for speaker cables
Recommendation for speaker cables
Follow the recommended maximum length for loudspeaker cables to ensure minimal SPL attenuation.
Cable quality and resistance
Only use high-quality fully insulated speaker 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.
The table below provides the recommended maximum length for loudspeaker cables depending on the cable gauge and
on the impedance load connected to the amplier.

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