Do speakers take time to warm up?

b_limo, the experience that is "totally different" IS totally different, because it's not simply listening to the same speaker again, or longer. It's an entirely different set of drivers, cabinet, etc. It WILL sound fundamentally different, and it takes time to get used to it as opposed to sitting down in front of the familiar speakers. It's quite simple. Is that speaker going to change it's performance over the first few minutes, hours, etc. you are hearing it? Obviously I disagree with some others here on that point. 

@douglas_schroeder , I agree that mental state plays a huge role.  Your mood, your sleep, your physical activities that day, all play a big role in sound.  I iusg have never thought about the listner adjusting to speakers; interesting theory.  You change speakers as much as I do only yours are much more expensive.  I value your opinion because you have quite a bit of experience regarding this... 

Pure baloney. Now if you substitute the word “subconscious” for “mental state“ gentle readers, I’m on board that train. 🚂 That’s what controls your sensory perception of sound. But you’re just not aware of it. Why? Because it’s subconscious! Hel-loo! 🤗 Please, no angry PMs.
