YouTube - Maelstrom-X
I have been breaking in my subs for years, and have frequently noted something that happens in this vid....
When I start, i bring the driver to it's point of mechanical discomfort... always freeair of course. Once i reach that level, I do not back off only a notch!!! I back off several, because as you clearly hear in this video, the driver breaks in and achieves a higher excursion with the same level of input. I break mine in over several hours in a room that I will be in for the whole duration, and sometimes I have to re-back down the input level multiple times as it begins to over excurt slightly as the compliance decreases.
I re-watched the vid, and noted there could be a few misunderstandings, then I scanned through this thread further (I didnt read the whole thing) and noticed there are other vids
Anyway, I noted:
up until 17 seconds, it is playing at low level, then he begins adding input...and it needs to be noted that the repeating track is increasing in frequency, generally excursion should go down as it gets higher. Would have made for a better example if it were a constant tone.
at 24 seconds the first hint is easily heard of nearing limits, then continues to increase... while increasing input as well?
35 seconds is the clear point of overexcursion
at 46 you hear it again, and he notes it, and backs off... but i believe he leaves it?
at 57 it overexcurts again... was it at the same input level since after he backs off at 46 seconds??
