Isolation disc for speaker spikes on wood floors.

I like these quite a bit:

They are used in combination with their matching spikes which I felt were a nice sonic improvement over the stock brass spikes that were supplied with the Coincident outriggers (which I don't use).

fully agree

How about cone coasters from Sound Anchors? I am using under my B&W 800's and two 15" subs.

The Herbies teflon gliders are nice and allow you to move the
speaker around to optimize the sound. I use them on a thin
carpet floor and really appreciate being able to easily move
the speakers if I have to. As an aside, Jim Smith from
"Get Better Sound" recommends these over spikes in
many cases, as the bass is more natural. Of course, that's
always going to be room and taste dependent, but I thought I'd
throw that in. For a non-sliding puck, I like the Linn
Skeets, as they have a small center hole for the spike to sit
in without damaging the sharp point. Good luck.

Palasr - intrigued by the viablue spikes. Wonder how well they would work over Herbie's gliders, which I am happy with mostly due to their maneuverability. Good looking spikes - any further comments, tips, etc on their application/installation?
