The extra wattage is a good thing in that his amps would be less likely to clip. The constant playing at loud levels should have caused soime audible damage if it was going to. Since it didn't cause anything obvious to breakthey may be OK. BUT listen to the speakers very carefully for rubs and or missing sound, the damage may be there even though it is not immediately obvious. So there is a downside, perhaps you can have them assessed by a pro speaker tech for problems.
