The Adam Actives I use in the bedroom only have a large chest of drawers approx 6' wide sited in the full width of an alcove as the best place to site them in my bedroom.
I use two layers of summat v similar to this with heavy granite trivet stands sandwiched between the foam top 'n bottom. The trivet stands are near ideal in size for the F5's footprint. The F5's sit on the top layer of foam & the transmission of bass frequencies into the chest of drawers is remarkably small.

Very cheap & very easy to neatly cut to size. :^ Sited like this the Adams feel reassuringly solid/very stable. Due to their weight & the security of their alcove placement it's hard to imagine any mishaps. Sooo no need to bluetack, which I've relied on heavily in the past when securely mounting compact monitors.
I think in this country we should sometimes be less brainwashed into thinking dedicated stands are the only solution for compact speakers. Obviously in many cases they may be the better solution. But in many cases furniture placement may be the only practical solution & may offer a much better aesthetic/be easier to live with.
Obviously some consideration should be given as to a speakers suitability for this. My F5's for example are particularly unfussy with coping with close to boundary placement & also it's fairly conventional to use Studio Monitors similar to these on desks & other flat surfaces.
I've also had great success with my centre channel speaker a fairly large MA silver LCR having been re-sited in the foot well of the the heavy oak desk under my TV. When I upgraded to the XTZ AP 100 power amp over 2years back the space the centre speaker was occupying directly under the TV, was the only place to sensibly site the XTZ amp & allow good unrestricted airflow.

I had obvious concerns siting the centre speaker in a vertical orientation in the footwell as it is close backed. It actually seems to sound even better. PaulF has suggested there could be an element of horn loading happening here. :? Seems to work well in any case & has not been the disaster I imagined at all.
It seems to me that 'stand-mount' as common use terminology for more compact speakers is mostly a relatively recent development. Weren't they generally called Bookshelf Speakers until sometime around the 1980's/90's.
