Speaker Stands adapters for Heavy Speakers?

Your top plate is just fine, really. Going to the edge won't make it any better. 1/2 or so around the edge is very normal.

Have to agree I wouldn't fret over an inch or so either way.If you needed a little more hieght you could add a piece of maple or Granite but I don't feel the extra added cost is worth the trouble...Just make sure you have a Herbies ( or something similar ) big Fat Dots in between stands and Monitor...........

D, most monitor mfgrs recommend blu-tak. The smaller plate would also be a design criteria. If the base plate is small I would use lead, not sand.

Thanks for feedback. I am planning on using blu-tak. It sounds as though it holds well enough to secure the speakers. Thanks for the suggestion about the lead, I think I will try that as well.

If the stands are metal I would consider decoupling the speakers from them. I have used Blu-tak but mine sound better with a set of cones with point upward between the speakers and stands. If I did want to couple them to the stands I would use cones with point downward. Metal stands are quite resonate even when filled with lead shot as mine are. If you have some small cones [Mapleshade, Valid Points, Star Sound, others] try them and see what you think. You do have to be more careful not to knock them over. Blu-Taked speakers have to be pried off.
