What happens if the peak power of treble speakers is pushed into them?

Im getting a JBL 145.5 speaker system in my room, this consists of 4 satellite speakers, a center speaker, and a 100W powered sub. Yamaha amp says that it will push out 140W surround. According to Best Buy the max power that can be pushed into the treble speakers (since the subwoofer is powered) is 120W and the peak is 150W. Will i damage the satellite and center speakers if 140W is put into them?
