A friend had a chance to install windows curtain pointed it out to me that the speaker's sock using same mechanism. Take it off is easy as some people already said, in order to put it back as easy and without damaging the speaker, you need a special tool, I don't know what it's call, but it looks like a plastic wheel on a stick, just rolling while pushing would do it perfectly fine.
Hales Design Group Speakers...Removing the Grills
I am looking for instructions on removing the grills from Hales Design Group speakers without trashing the material. I'd also like to be able to put them back on :). I found some instructions suggesting that you lay them on their back with some books to space the binding posts off the ground...any more technique than that and pulling/prying? How are they actually held on?
