ITC wall-mounted speaker, likely a commercial/public-address (PA) speaker.
If you're asking whether the Su-Kam 2 × 1.5 mm2 cable in your first photo is suitable for this speaker: yes, that cable is more than adequate for a typical ITC wall/PA speaker installation. The exact connection depends on whether this speaker is a 70/100 V line speaker or a low-impedance model.
If you show me the back/label of the ITC speaker, I can identify the model and tell you exactly how to wire it.
