For maximum effectiveness spikes should not be run
through any type of carpet interface (carpet/foam).

Shows lack of empirical evidence with speaker spikes. I've owned speakers
that came with them, it was easy to observe that their sharp tips cut right
though the carpeting and made solid contact with the harder substrate.

If you have high quality carpet, spikes just won't
penetrate the carpet/pad substrate.

Now you are contradicting yourself, Powell. First you make an absolute
unqualified statement, and then you limit your discussion to just a tiny
subset of all carpeting.

Nevertheless, you're still wrong. I've found that speaker spikes, when
attached to a suitably large and heavy floor-standing speaker, will cut into
even thick carpeting over thick padding. Perhaps your experience with
speaker spikes was obtained with a speaker that was too small and light,
such as K-Mart mini-monitors on a Wall-mart speaker stand.

The tightly
woven jute backing and under pad are the problem.
The conical shape of spikes simply will not couple
to the sub-floor... and I mean tightly. While it might
appear (feel) to you that your spikes are firmly in
they are still supported by the carper/pad. Sound
pressure measurements and auditioning indicate
only a poor improvement in fidelity if used in this way.

Then you're wrong again Powell. There's no evidence that there are anything
but trivial effects due to mechanically coupling the speaker to the floor.
I've seen the results of measurements on speakers that were sitting on
cardboard boxes and even hanging from the ceiling with fishline. Have you?

OK, gotcha. Thanks, Arny. Now what about things like
concrete cabinets?

Materials cost low, production and shipping costs high.

I have a small pair of Rauna speakers that I
like and they are made of concrete. Even though they are "bookshelf"
size speakers they weigh about 45 pounds each. Would you consider that
type of construction to be way beyond the point of diminishing
returns or would the significantly heavier concrete walls just be
similar in effect to the extra bracing you mentioned?

I think that current wisdom is that the ideal materials for making speaker
cabinets are not rock-hard but have a little give with some internal
damping. MDF has its moments.

Hehehe... oh right! Please site one major studio
monitor manufacture that doesn't tightly integrate
spikes in their design. You obviously have never
hear of manufactures like Wilson Audio, B&W,
KEF, Revel or Focal have you, old man?

Exactly. And you were the idiot who was claiming they don't work.
