Infinity RS Kappa serien blev produceret fra 1987-1989. Det er den originale Kappa serie, ej at forveksle med Kappa II serien og de (under Harman) dansk producerede Kappa 60 til 100 modeller.
De to største modeller, Kappa 8 og 9, adskiller sig i design fra de tre mindre. De har ret flade, lukkede, kabinetter, der står vinklet bagud på en stålfod. De er blevet kendt (og populære) for at have en voldsom bas, kombineret med meget fint detaljeret mellem- og højtone. Begge kræver kraftige forstærkere der kan klare meget lave impedanser.
