I noticed that "The ElderEquine" specified, "There is also no need to break in any
Subway cabinets, ... changes are
virtually unmeasurable."
[emphasis added]. This probably applies to other good quality brands and products, as well. I did
not notice a need, or a change, in the speaker sounds of my multiple Fender Bassman or Rumble combos or cabs.
I
did quite definitely notice a
need, and a change, in the speaker sounds of my Vox VX50BA over the course of a couple weeks of near-daily practice and knob tweaking and short-term volume cranking. See my comments on this here:

Around that time I also did a bit of TB research on speaker break-in. As you can imagine, I found everything ranging from "totally no need for
any speaker break-in, ever" to "every speaker always needs intense break-in", and everything in between. So, as is usually the case, agedhorse's referenced statement is the voice of reason, and experience, between extreme opinions.
