Hero? Well hell you should love this. This shows break-in but within the first 60 or so minutes only.

In summary, some woofers will not produce a normal amount of bass for a few minutes when first used.
The drivers could easily be broken in during quality control testing at the speaker factory ... but if not,
they will break in quickly at home.
The driver tested below had a significant change in the first minute of use ... and almost all the changes were in the first 60 minutes of use. There is no indication that extended break-in (10's or 100's of hours) was needed.
This Seas driver was tested by a company named
VAF Research Pty Ltd. and the results were reported by Philip Vafiadis.
The driver had an xmax (linear stroke) of +/-6mm but the break in tone only required +/-2mm stroke = not much of a stroke and probably made break-in take longer than necessary.
Results:
Qts with no break-in = .49
Qts after one minute = .42 (change probably audible)
Qts after 120 minutes = .41 (change vs. .42 unlikely to be audible)
Fs with no break-in = 35.47Hz.
Fs after 60 minutes = 32.03Hz. (change may be audible)
Fs after 120 minutes = 31.62Hz. (change vs. 32.03Hz. unlikely to be audible)
