I have a Kenwood KR-720 25amp Receiver rated 4 to 16 ohms. I don't know the rated power to watts for the speakers. I am interested in buying the Klipsch KLF-20 with the KLF-C7 (I think) center speaker. Will my Kenwood be OK ? I am currently using JBL Radiance Series speakers but they are 20yrs old and worn out (like me).
