Question about Klipsch R-820F

This works without any problems (the box has a pretty good efficiency). Digitec has a good article on the whole subject:

No problem. In general, it is important to ensure that the amplifier is never turned up to or above the power limit. Otherwise most amplifiers will switch off. Switching off is a steep signal edge and is therefore sent directly to the tweeter by the crossover and destroys it.
Elegant amplifier.

Super danke!!!
