Speakers and air-conditioning

Can air-conditioning have a negative effect on speakers? I suspect that it can, but I want to get some others' input.

Believe it or not, a superficial googling of the subject ("speaker air conditioning") didn't bring up anything relevant.

My sense is that it can be too effective against humidity (for our purposes), and dry out speakers to the point that SQ is negatively affected. I would guess that any circuitry or current-bearing wiring might also be chilled to the point that they need some warm-up time to get back to normal after periods of air-conditioned slumber. Do I think I may be hearing some of this in my often-air-conditioned speakers? I do. But I'd like some confirmation or input from people with more experience/insight/expertise.

Of course, generally speaking, it's our friend; I know my amplifier likes it. But I'm not sure it's my speakers' friend. And when it's hot out, my speakers are often in an air-conditioned environment.
Loudspeakers for home use are designed for the same temps humidity levels etc that humans find in there homes. So why worry?
This is a very valid question. It is well known that back in the 19th century, before houses had electricity, and therefore, no air condtioning, speakers lasted a lot longer and required little if any warm up time.
Humidity can mess with wood musical instruments like acoustic guitars (big time...I adjust necks all year), but speakers boxes are so thick I can't imagine an issue, and drivers are usually coated with enough goo to avoid saturation. Unless you live over a swamp or have a treehouse on a beach I wouldn't worry. By the way...my wind up Victrola requires 8 minutes of warm up time to sound it's best, as does my wax cylinder player. I leave 'em on all the time.
When I was in college, I used to love my summer job as an installer in telephone exchanges partly because of the air conditioned environment required by all the electronics.
Actually...I bet humidity has a larger effect on a system than many of the precious little tweaks we get caught up in...so I say it was a great question, albeit apparent mirth fodder.
Humidity affects the density of the air and can affect the sound. It can also make poorly made particle board turn into fallaparticle board. Especially over a long period of time.
If the humidity is melting your particle board, move. Immediately...before you melt.
