Sarcasm was not necessary. It is important that you understand the shape and size of the speaker in order to provide a workable solution. Please don't bother to answer if you're not going to contribute constructively. You're just wasting everyone's time.
Think I'm going to have to make my own. I'll have to get a piece of thin wood, cut it to about the size of the speaker, paint it, and then attach velcro straps to it that hold the speaker in place. Then I'll mount the whole assembly with super strong velcro on the backside.
