Are SW100 & SW102 Passive Radiators Interchangeable?

Asking because my pin/blade CRS+'s have the SW100 PR's. The research I've done here indicates that they should have the 102's. I am the original owner- purchased new in the late 1980's. The MW's are correct for that year and model. I guess Polk thought the 100 and 102 were interchangeable- any thoughts? Thanks, Don
