Just did one today.

It sounded like someone farting on a snare drum. Very thin, no base at decent volume.

The mount is stupid. The Beam stuck out around 2" further than the display.

HDMI ARC is dumb because this client had a cable box, appleTV, BluRay, and Xbox. The Beam takes up an HDMI input on the TV. We couldn't get the optical/hdmi dongle thing to work right either.

Luckily we sold the TV, remote, and install, and they got the Beam direct from Sonos.

I think it makes decent sense to use it on a tv that is not wall mounted and the playbar and playbase don't fit.

I have two on order, so I will let you guys know once I get them how they sound with a sub.

Not impressed. Might not be bad for a guest bedroom or master bedroom where forking out $700 for a playbar is not realistic.
