For maximum effectiveness spikes should not be run
through any type of carpet interface (carpet/foam).
If you have high quality carpet, spikes just won't
penetrate the carpet/pad substrate.

If by pad you mean underlay, spikes I've used just do. Certainly helps a
lot with wobble, especially with small footprint floor standing speakers.

Indeed, I've just remembered that the pair of LS3/5A's I have on stands in
the dining room also have spikes - for the same reason as you mention. On
tall stands and wobble alarmingly or may move around if bumped into unless
spiked. They also penetrate though quite a thick carpet and underlay.

Maybe none of us have "high" enough "quality" carpet. Can't say as yet as
these are also words Powell has used without providing a measurable
definition. The phrase "vague and sweeping assertions" does come to mind.
Maybe "sweeping" is relevant for carpets, though... :-)

Slainte,

Jim
