The RS2.5 has the famous, and outstanding, Watkins dual voice coil woofers. You likely would not damage them by wiring them incorrectly, but it does affect the sound (ask me how I know!). The links I provided above will show you the wiring diagram, with wire colors shown.
FYI, for all things "vintage Infinity", go to the Infinity Loudspeakers forum at Audiokarma.org.......

Good luck and enjoy.
