Do speakers take time to warm up?

I use pink noise track (#15) on Stereophile Test CD when I turn on the stereo after it has been shutdown for sometime. I shutdown the system whenever I am traveling. I unplug everything even if my wife is at home.

So when I turn the system back on, I find running the pink noise track helps to bring the system back to normal. I run this track very loud at 12 or 1 o’ clock position. This has nothing to do with breaking-in of components, but rather forcing all of the components in the chain to come alive.

My main issue is I have tube preamp, DAC, and phone stage. So no matter how hard I try, I still need to wait until tubes warm up and settle down. But pink noise certainly help to get the rust out of speakers drivers if any quickly after not using for sometime. However, I don’t feel the need to do this everyday or every time I sit down for a listening session.
Hope this helps.

+1 @pwerahera I do the same thing. I have a 70 minute disc of pink noise at all frequencies that I let run for half an hour or so at high volume. Great for the entire system.

We're not talking tube related warm up here. At least I'm not. 

@douglas_schroeder , do you believe that the speakers mechanical parts need to be warmed up at all, like a cars engine when you start it in the morning?  Like the surround and voice coils Need to loosen up a bit?  
What about caps in the speaker?  
Caps in the amp?  If I leave my amp on 24/7 it’s warm and teady to go whenever, right?

Thanks for the response! 

b_limo, my understanding is that the speaker drivers have an initial "break in" but is very short duration at the factory, and perhaps somewhat more over the initial period of use, more on the order of first few dozen hours, not continually as if reverting back to an initial state.

My guess is that any "loosening up" would be in the first second or two upon using them. How is a person supposed to determine from listening that any kind of loosening up has happened when human hearing is not as consistent as electronics? Forget about it, as it's a waste of your time. Put your time/money into getting better gear.

I move speakers in and out continually, and I pay no attention to such things. To do so would be a waste of time for me and lead to far less productive system building.

I don't know that your caps are charged even if you leave the amp on. No signal to the speakers.

Work on the major things that make improvements, not the cheap, low grade things. Do not settle for insipid, low productivity changes.

How about tube degradation? Why not worry that leaving your tube amp on is slowly degrading your sound via shortened tube life? Is the benefit of speaker "warm up" overcoming the degradation of tube wear? See what I mean? Forget the nonsense, and work to achieve vastly superior sound with a better system. Save your money, get better. Forget the junk methods. An audiophile can waste their life in pursuit of questionable activities instead of going after far better experiences. Don't be someone who wasted 20 years on the inconsequential stuff as opposed to getting a grand system.
