Digital Coaxial to dual wire speaker

Hello,
I have a odd question. I have a receiver that has digital coaxial outputs for each of my speakers but my speakers only have dual wire inputs. Can I easily convert my speakers to accept the digital coaxial inputs?

Are you sure they are designed to feed speakers?

What kind of receiver?

The only digital output that I am aware of is the S/PDIF output which is a low level multichannel electrical (coax) or optical (TOSLINK) output:

The S/PDIF output would need to be decoded and amplified (something that already happens in your receiver) to drive the speakers. They cannot drive speakers directly.
