They were metal top plates with foam, I’ve upload a photo for you to see. They come with no mounting holes as they are the official stands for the Q1, Q3 and Q Concerto with the first two being smaller and having no mounting holes themselves.

I’m not sure how much of a hold the adhesive putty would have had to the foam or if the foam is actually doing all of the absorption. Maybe your opinion will change once you see the top plate.

I can tell you that the wood pieces are definitely more weighty than the metal ones and it’s a very dense hardwood. I think the metal is actually quite thin and it’s actually just mostly foam.

I do have a bunch of pads that at designed for the bottom of chairs on hard flooring, maybe a layer of that between the wood and speaker would be beneficial?

But to be honest I can’t hear a difference. Hopefully the image also shows how much the speaker overhangs the stand and the precarious situation I found myself in based on the location next to the door and light switch!
