Questions about Flexson Sonos PLAY:5

Yes, that's how I installed it.

No, unfortunately they do not fit the 1st generation Play:5.

The manufacturer doesn't seem to give any information on this and I didn't find any other precise answers to your question. I assume, however, that this should be possible. If not, you should be able to return the item if necessary.

Scheint so, als ob man die SONOS PLAY:5 darauf "montieren/fixieren" kann. "The Flexson Floor Stand for the Sonos Play:5 puts your speaker at the ideal listening height and holds it in either a horizontal or vertical position." https://www.flexson.com/flexson-floor-stand-for-sonos-play-5-563

For mounting for the wide path, you can also use this stand.
