why spikes under speakers???


could you guys educate me about the use or need for spikes under speakers, it seems to me that putting an air pocket under a speaker would be the last thing you want to do, isnt bas about pressure? and if you put a gap of air between speakers and floor arent you losing some of what makes bass work? I am not claiming this to be bad, I simply want to pose my questions about this concept and get educated on why this is a good idea, and when it may not be a good idea...thanks

I started this because I am looking into VMPS ribbon tower speakers, and Brian does not suggest using spikes, these speakers have slot loaded bass, I have AR-9 Towers now wich I cant imagine putting on spikes, but the VMPS designers recomendation got me wondering..wich is why I posted this thanks all for your knowledge
I don't use "spikes", I use Audiopoints.

These actually do work.
I never confuse "spikes" with Audiopoints, since they are totally different devices, that happen to look similar to other spikes.

S7horton..."knowledgeable" on this subject, perhaps, but that's not the same as "intelligent".
OK, then let me rephrase:

The idea that spikes or cones or Audiopoints "drain" vibrational energy from anything is quite possibly the most absurd idea I have ever heard. It is not only totally ridiculous, but physically impossible.

Feel better now?

With that said, note that I do not claim that they do not work, or do not help to improve the sound of speakers put upon them. In fact, my opinion is quite the opposite. They DO work and the effect they have is easily discernible in many situations. They just don't bring about that effect by draining vibrational energy as Blkadr suggested. This is an absurd concept which has no basis in physics or fact.
