Subwoofers, Bass, and Transducers
I see that I have some ringing going up to 2100ms, mostly <300 Hz, with modal frequencies shown with the colored bars at the bottom of the graph.
Image #2 is scaled at 500ms max time, with 100ms window.
SPL curve is shown in image #3 with 1/48 octave smoothing.
Measurements were done with Yamaha...
