From 3.5 billion Reddit comments

There's this (expensive though $50): https://www.pcrichard.com/Generations/Generations-Wall-Mountable-Component-Shelf-Black/GT1.pcrp

^ I own this one so I can measure when I get home if you need dimensions. Grabbed it cause it was rated for 30 lbs (couldn't find an Amazon one rated as high at the time).

And otherwise there's these: https://www.amazon.com/Best-Sellers-Home-Kitchen-Audio-Video-Shelving/zgbs/home-garden/509304

EDIT: A potential match - 30lbs rated, $35, 18" wide: https://www.amazon.com/Mount-Floating-Component-Playstation4-Projector/dp/B008OBHY2Y

Put the speaker on one of these and then buy the piece of furniture you like rather than worrying about making sure the furniture is high enough for the speaker.
