Is it normal for the woofer to move in/out slowly


My only tubed piece is the pre-amp. It is the only piece I turn off when not in use. I noticed that when I turn it off the woofers on my speakers move in and out rather slowly while I hear what I assume are the tubes discharging.

Is that normal and more importantly can it cause damage to the speakers?

Thanks

Here's a question I have concerning this. What would damage the tubes more, surge from turning pre-amp on and off repeatedly or leaving pre-amp on most of the time?
