The video asks three questions...

1. Can your loudspeakers reproduce all of these tones?

2. Can you hear them?

The audio in the upload is in 24-bit WAV format sampled at 192 kHz, so the quality of the original file is about as good as things can get. But how you hear the tones depends on the three factors listed above.
