Every size below is a published model in the same construction, read from each model's own specification sheet. This page is the 2.5 mm² size (14 AWG) with 4 conductors and a 11.5 mm jacket.
4 conductors carry 2 loudspeaker circuits: one positive and one negative conductor per circuit. A two-pole connector carries one circuit, a four-pole connector two — the pin-set rule is explained in NL2 vs NL4 vs NL8: Speaker Twist Lock Connectors.

In the same 4-core construction: The next size down is 2.0 mm² (15 AWG) with a 10.5 mm jacket. The next size up is 3.0 mm² (13 AWG) with a 12 mm jacket.
Cross-section, not the model number, sets conductor resistance and therefore the loss over a given run: the length-versus-gauge table is in the speaker cable gauge guide, and the mm² / AWG conversion is set out in mm² to AWG.
