Do you ever have to re-break-in speakers?


Odd question but I recently purchased a barely used pair of speakers. I'm sure he listened to them long enough to break them in but then he moved to another model and they sat for quite a while before I purchased them. I've listened to them for a few weeks now and I swear they sound better now. Do new-ish speakers stiffen up again if left unused for a long period of time? Or are my ears just getting used to them?

OP, In my experience, yes.  I had the same situation as you where the previous owner hadn't used them in a while.  The bass was anemic when I first started playing them but, after 10-15 hours or so, they started to loosen up.  It's not hard to imagine that rubber surrounds need to be played to stay flexible.
If it's in the bass, then it's the drivers.

If the treble opens up, the caps.
Absolutely, I needed about 170-200 hours on my speakers before they owned up, even now, after sitting for months at a time, they need a bit of warm up, 
amps, preamp, CD player, speakers all need break in

 I have good ears, and I can heara huge difference after hours of warm up and low volume playing vs. a cold start and music.

bass deeper, better highs, more in your room guitar.

not a myth.
