Correct on the high power being easier on some drivers, if it's clean.
I used to blow tweeters on the D9's with lesser powered amps, even with fuse protection and the D9's have a circuit breaker on the tweeter if I remember correctly. Anyhow, once I went WOPL 700, no more blown tweeters, at all. Just blown 5A fuses during cranking sessions. I did run them with solid brass in the fuse holder for a bit and it just felt like a little more and things would break. I heard distress but sounds like it wouldn't have taken anything out. Always listening for driver distress as I have taken out many......
