If those are later series Rogers organ speakers, their value intact is probably higher than their component value.
Organ speaker systems are specifically matched to sound really nice with the organ. They tend to work very well in the lowest octaves but may not have much output above ~ 12kHz, since they don't need it. They also don't need to handle the human voice, and cutting edge transient response isn't critical.
Not saying the components aren't good, just saying the components might not be big names with big resale as components.
