Logitech Z-5500 Question

I am new to this site as you can tell, this site looks real nice, I love the layout. Well I came to ask a question, and the question is towards the Logitech Z-5500 Speakers. Is it healthy to shut off the subwoofer, cause there is a switch on the back of it. If the subwoofer + speakers is like a computer’s hardware, then turning it off and on is not healthy. What do you guys think, is it healthy or not?

Leave it on…mine has been on for over 2 years and no problems.
