speakers are around 99.7% inefficient.
So 1000 watts in, 30 watts out in musical output.
I would actually say that because music is so dynamic that it's more like 30 watts into the speaker when you're cranking the volume. For a fraction of a second it might spike to 200 watts but speakers typically don't even handle 20watts of continuous heat very well.
Ever heard those stories about 20w solder guns ruining speakers because they didn't clamp heat sinks? I certainly have a hard time believing that our amplifiers ACTUAL heatsinks can wick away 1000w of heat continuously.
Here's an example where watts are being used to heat.

"Efficient" depends on what you are measuring: 5% efficient when used for lighting, but 95% efficient when used for heating
Good for a laugh: Heat Balls.
Random: Look for heatbulbs, which emit radiation at an even higher heat-to-light ratio (making them more "efficient" for heating).
