Thomann Cover Pro dB FlexSYS FM12

It's a nice dust cover, intended for covering the speaker when they aren't used on stage or in storage but this will not protect them enough if you are moving them with a truck or a car. Get a case and build some custom padding if you need to tour with them. This doesn't cover the bottom of the unit like some other covers for other speakers do with some velcro to close the cover.

I bought 3 recently with my FM12 Monitors. As a protective cover for light use they are excellent. I am not sure how much abuse they will take for hard working bands etc. who would be moving them about constantly, but for normal general purpose use they are an excellent and essential extra. I would recommend them.
