What does clipping sound like?


I have been wondering if the break up distortion I hear with my 60 watt tube amps is because I have insufficient power for my 91db 6 ohm minimal speakers. I do question if that rating of my speakers is correct.
When the music swells, I get break up sound. It is not on low notes or high volume. I do wonder how my speakers would perform with a lot more power. I have always thought that any speaker likes more power.

It’s not clipping if no correlation with turning up the volume. Something else then that would have to be isolated by testing one change at a time.
Damaged / worn out speaker surrounds fit the bill....If you have push-pull tube amp, then a misalignment in the phase splitting can be the culprit of this phenomenon - either one tube / tube section got worn out, or a plate load resistor went off value due to too much heat stress.91dB speakers & 60W amp should not be an issue... have you tried both 4R and 8R output taps on the amp? Try it on the 4R tap if you've been running it on the 8R so far...

Absolutely no idea what is going on here. Except for one thing: "when the music swells". When the music swells is called a crescendo.
