I trust JBL's opinion, and I have also had this explained to me by a professional speaker designer.
Clearly you haven't bothered reading the articles you quote to people.
It is explained in your article that the only way for clipping to actually cause any thermal damage is if the amp is overdriven, and then it will only, theoretically, be able to output twice its rated wattage.
The OP's speakers can handle up to 100W. His amp delivers 13W. Even overdriven to the point of doubling the wattage (26W), he will not come even close to being able to damage his speakers. Thermal damage (average power over time) can only happen if said power exceeds the speakers' limits, which isn't the case here, and very very rarely is when lower rated amplifiers are used.
So while, theoretically, it's true that clipping from an amp that's rated lower can damage speakers, achieving that by accident is almost impossible.
