How to mount my......

Does anyone have recommendations on how to wall mount B&W 805nautilus? I use them as rears speakers in my HT. I have a very curious 10 month old and the stands won't cut it. Thanks in advance....
Maybe a shelf and some blue tack.
I have some very heavy wall mounts that bolt to studs and have an adjustable platform. I used these for Polk LSi9 speakers which are quite large and heavy. If you pay for shipping you can have them for free. Message me if you are interested.
I found the product page for the speaker brackets that I have.
Thanks all for your help. Much appreciated.
