Best way to attach speaker to stand?

Thanks for the replies.
Would it make sense to use the spikes and screws? Should I spike the base too?

If you are able to drill holes in the top plate of the stand, you might be best off to set the speaker right on the stand and bolt it right to the top plate. Similar to the way B&W speakers mount to their matching stands.

Ditto. Even with the GMA Europas, which I had been assured were so vibrationally inert due to their cast marble enclosures that you wouldn't need spikes, I heard distinct improvements after spiking them on top of Osiris stands. You can do it with the spikes pointing up or down in my experience, though I usually turn them down to avoid scratching the speakers themselves. Every monitor speaker I've heard in my system sounded better spiked on top of the stands.

Personally speaking, I prefer to use some type of an audio point or spike (three per speaker).
