Quick ohm/amp cab question.

How does a 440 watt amp deliver 800 w 🤔

Please read Bill Fitzmaurice's post a little further back in this thread. This isn't a contentious point.

The bottom line is that an amplifier capable of delivering ANY watts at ANY ohms (possibly ANY watts peak) is capable of damaging ANY ohm cab with a thermal rating of ANY watts if you ignore signs of the speaker being driven too hard.

 

Fixed it for you.

Perfect, thank you. Totally agree.

So you're warning us about running an amp at full power, not at half power.

How do you know? The knob position doesn't reveal the amp power output, nor does anything else. With a low voltage input signal the knobs could all be wide open and yet the output -10dB or more from rated output. With a high voltage input the knobs could all be at 9:00 and yet the output +6dB over rated output. I once blew a 200 watt EVM-15B with a 50 watt amp when I hooked up a pink noise generator for testing. I didn't realize that the generator was cranked, so when I turned it on the voice coil blew in less than a second.

Just to be clear:  a volume control does NOT limit the power that an output section is able to deliver.

Correct. It is only limited by the maximum voltage , maximum current (amps) and the imagination of the marketing department.
