Old Traynor PA speaker with two inputs - reason?

[MakoMan]

This is probably a dumb question but I cannot find the answer anywhere by searching.
I was given an old Traynor CS-210 PA speaker which appears to have two 8 ohm input jacks. Is one a spare? Is it for chaining? Or can I plug both sides from a PA into this one speaker?
One of the reasons I ask is I have an old but mint Traynor YVM-3 Voicemate that I would like to use in my little jam room, but I need speakers.

It is for daisy chaining to another speaker. DO NOT plug both sides of the amp into the cab or you will release the magic smoke.

Thanks! That's pretty much what I figured!
