I was not suggesting that anyone develop a speaker power handling test. That is the most irrelevant and abused spec in all of audio, because if a speaker is efficient enough, it doesn't require a lot of power.There is a issue with having a power handling test in that it can be a destructive test. What @amirm does is NDT (non-destructive testing.). To use destructive tests is to need a repair workbench, more instrumentation, spare parts, many tools, the space for that and money for parts to repair peoples' gear that has been damaged during testing. That's why he does not heat/power soak gear in testing it. To avoid break-down issues.
I was referring to a test of two (or more) frequencies played at once, and measuring the distortion, as described in this post below, and in the YouTube video that Amir did that I provided a link for. But instead of listening to music with two or more tones played at once, develop a signal test that outputs 2 or frequencies at once and measures the speaker distortion.
Buchardt S400 Speaker Review
I didn't say that we can always listen to speakers or other audio products before we buy them, I said that is the ideal situation, especially for speakers. For example, the S400 is only available via direct order from the manufacturer in Denmark. Did you read any listening test reviews before...
