Is coaxial cable better than copper cable for spks?
Copper is material
Coaxial is construction type / form factor
Coaxial are usually made of a copper center conductor like most wires. Shield can be made of whatever
Going one step deeper, there are also cable standards, like RG6 for example is a coaxial with 75 ohm characteristic impedance. (Worth noting is that cheaper RG6 use copper-clad steel for the center conductor)

Or in other words, question is invalid

Coaxial is more expensive than just 2 bare wires and there is no advantage using it for speakers. Doesn't mean you can't, tho. As long as DCR is low enough, and RG6 has pretty decent DCR. Proper cable manufacturers like Belden and Canare have datasheet available.
