According to this chart, it seems that gauge and cross-sectional-area are inversely proportional (larger cross sectional means smaller gauge).

I am finding it hard to understand a statement in my speaker-manual:

"Always use good quality speaker cable with 2.5mm minimum cross sectional area per conductor (79 strands)...For cable runs longer than 5m use a significantly heavier gauge cable."

The first sentence seems to recommend a wire that has at least 2.5mm cross sectional would mean wire with gauge 10 and lower?

The final sentence seems to recommend heavier gauge does that mean larger gauge? Because that contradicts the first statement? or does it mean lower gauge?

Heavier gauge means a lower number as your chart indicates.
