You just need some plain and simple speaker wire. You have bought decent speakers so it makes sense to use some reasonable quality cable without going mad.
Cable quality goes on thickness and whether it is oxygen free or not. This slows down tarnishing. Thin bell wire isn't oxygen free and it's cheap but rubbish. Avoid.
Decent thickness is anything over 2 x 1.5mm CSA (cross section area). There's plenty of stuff on Ebay that's cheap enough

Have a look at the speaker terminals on the backs of your speakers. They unscrew to reveal a post in the centre. Unscrew far enough and you should find there a hole through the post for threading the end of the cable through before tightening down. This is a better way than wrapping the cable round the posts. Alternatively you can buy something called banana plugs to add to the ends of the cables. Check your speaker manual about removing the binding post plugs that cover the holes for connecting banana plugs.
It's also useful to check how the wire fixes to the amp. If the amp has the same type of binding posts at the speakers then there's nothing else to check. If it uses
spring clip terminals instead then these won't take wire much bigger than 1.5mm CSA.
Now, you haven't mentioned the amp. If you bought these speakers to replace the ones that came with an all-in-one home cinema kit then you're going to struggle.
