Unfortunately, I couldn't find what I was looking for either, so I decided on wall mounting with the Vogels Sound 3200.

I have the RS5, but so far I haven't found a suitable stand that looks OK. If anyone finds something, I'd be happy for some information. Currently, I only use them sporadically for movie nights, but I don't turn them on for short TV shows or anything like that, because they are still running on battery power.
