Question about JBL Bar 9.1

These are the official dimensions:

884 x 62 x 120 mm / 34.8 x 2.4 x 4.7 inches (soundbar)
173 x 60 x 120 mm / 6.8 x 2.4 x 4.7 inches (detachable surround speakers, per unit)
305 x 440 x 305 mm / 12.0 x 17.3 x 12.0 inches (subwoofer)

Just like Paescebu, I wouldn't recommend placing anything above it.

I measured it manually. It is exactly 5.8 cm from the floor where it is placed.

But I hope they don't want to put it somewhere "underneath". Because this thing has upfiring speakers for Atmos. If there's something in the way, the bar's usefulness is somewhat counteracted.

Thank you very much for the information!
I am looking for an Atmos soundbar with rear speakers that can be placed in front of my TV (lgoled65e9).
I am running this on the stand and the soundbar must not be higher than 6cm otherwise the picture will be cut off.
I know, on the wall would be the better solution, but it's too inconvenient for me :)
