Three pure tones of increasing frequency, combined into a single signal comprising three pure tones of increasing frequency.
I played the three tracks at the top simultaneously.
I could have played the mix track, just created now so you can see the combined signal.
In the first video, you see (and hear) three tones, increasing in frequency. Along the bottom is the Noise Floor of the room/measurement system. The Red is a history of the Peak SPL by Frequency for that test sweep.
In the second video, you see (and hear) three tones, along with the smaller tones of Harmonic and Intermodulation Distortion Products the speaker is producing as it exceeds its comfort level, as the three Tones slowly increase in frequency. Again, the Red is a history of the Peak SPL by Frequency of that test sweep.
The Audio portion should enable you to heard the undistorted, and the distorted output of the speakers.
