Do speakers have to "warm-up" too?

i warm up my amplifiers for 30 minutes before listening (everything else is on "standby" all the time), but i strongly feel that
the (first) cd i have on sounds (much) better (fuller, more open sounding) towards the end than it did at the start. i get this impression time after time. my speakers are broken in of course, but (perhaps) they become more compliant, or the voice coils warm up (?) i'm not an engineer, but it makes sense that speakers reach a sort of "equilibrium" after playing music for a given period of time. otoh, of course, my ears could be "adjusting" to the sound, and/or the effect could be largely psychological. does anyone else have this experience or feel the same way i do?

Sure, speaker probably do have a warm up time. Many contain capacitors, resistors and inductors that change as signal passes through them.

My Sound-Labs were very slow to warm up in spite the amount of time the electronics had been on. Sound-Labs back plates contain two large transformers, (one EI and one Toroidal). Also, 8 or more resistors (depending on which version you have), a brilliance control, switches for mid and bass EQ and several caps. All these are in the signal path.

No doubt there are other examples of speakers with similar parts, even if much fewer that this example.

As for the voice coil improving or suspension freeing up too? Could be, I would not argue with anyone who says it does.
