Sadly they're unavailble at the moment on amazon, so I will try and look elsewhere for them. Thanks for the link it's a great help.You can get it from Amazon UK.
It came with different type of adaptor plates you can mount on the speaker stand (see photo). I'm using the flat one (11) x 2. I just placed the rear speakers on top that's it and can be removed for charging easily.
See link for manual. The model is Sanus EFSAT-B1.
