Floor spikes for speakers?

Spikes are good for poured concrete under your carpet. If it’s a suspended wood floor, be it on your first floor above a basement or crawlspace of on your second floor, spikes are not good. 
 

In that situation, you want to look at solutions that help dissipate vibrations, such as isoAcoustic Gaia:s or Townshend platforms. 

For my Revel Salon  2 speakers on carpet I used the IsoAcoustics Gaia's with their carpet spikes which they  sit on.  Big improvement in imaging and tightening of bass.  The Gaia's alone on carpet are a bit tippy.

@bimmerlover , I’m a firm believer that decoupling is better than spikes on “ Carpet over concrete “ as I stated above. I spent a few weeks trying spikes , no spikes , Townshend Podiums with the entire system on the long wall then the short wall. This is my experience and I’m not gonna be that guy who projects my experience on someone else’s truth. I was a spike guy forever and had to try it for myself. Respectfully, Mike B. 

I went through the whole deal with spikes, no spikes, platforms etc..  On a traditional wood suspension floor, isolation is the way to go.  There are always new and different isolation devices.  Mine are Townshend podiums.  For me it’s an essential absolute product in this type of environment.

Like the majority here suggest, if you don’t object to spending the dough (they’re not cheap) the Townshend Seismic Podium is the way to go. One way to get Townshend isolation cheaper is to buy sets of Seismic Pods instead of the Podium, especially if the speakers have dedicated bases. For instance, a set of 3 pods may be bolted onto the stands Sound Anchor makes specifically for the Eminent Technology LFT-8b. Another tip: For use on carpet, the spiked tripod bases IsoAcoustics makes for their GAIA feet may also be used under the Townshend Pods.

If the Townshend Podium (or even the Pods) seems overpriced, a set of simple (load-rated) springs may be used instead. Former AudioGon contributor (and very interesting guy) Geoff Kait markets sets of springs on his Machina Dynamica website. I have a set of his cryo’ed Baby Promethean Mini-Isolator Springs under my 47lb. digital player (the Townshend Pods are too tall to use with the player in the Solid Steel rack shelf space it sits in).
