Visaton BG20 8" Full Range Driver Sealed Monitors

Hi
How well these handle power? Would these be suitable for lower volume guitar monitor/amp.

I have them running on a 50w class AB amp currently. Seems to handle well. But I don't have them flexing their excursion as I have them limited to about 100hz before I integrate a sub. So I imagine the design and bandwidth you run it at will matter for power handling. It'll handle power, but I'm not sure how much before you get lots of distortion, etc.

Very best,
