Crutchfield Customer Review (What's this?)
Really great fairly low profile mount. I also have the Pro 90s but much prefer the discrete look of these and will be swapping out my 90s. I'm not sure how much weight they can handle but are perfect for smaller speakers I have used them on HEOS 1 and SonoS play 1s without any issue.
Pros: Discrete and low profile
Cons: Not sure how big a speaker you could mount
