Speaker Bass

spikes, the more you raise, the less boom. Same as if moving them further away from walls.

Adona platform shelves worked for me. Place the granite side face down on the carpet and rest the speakers on the MDF side. You can spike the speakers into the MDF if desired. Another benefit of this is that I can move my speakers very easily, no small task considering how heavy they are.

I thank everyone for their suggestions. I am going to try two methods. One is to try to isolate the speakers and the other to have the spikes turned to a finer point. Again thanks, Steve

put 50 lbs on top of the speaker to reduce any cabinet flex

My listeninwg area has carpet over poured cement. I've put my speakers on wood on Travertine tile. This should be something you can try with purchases (mainly) from the local hardware store. If the WAF is not there, you won't have spent a fortune. For my system, "rubbery" options didn't sound good. Seemed to lose focus. FWIW, my system is posted. Good luck.

I use Isoblocks (laminated cork and rubber) which do a decent job of decoupling without sucking much life out of the sound. The bass is pretty tight, but has a certain warmth to it that I enjoy.

I had exactly the same situation as you describe and tried various spikes, V-pads, platforms, etc.

What I finally settled on were Herbies decoupling disks which fit between your spikes and the carpet to efffectively isolate the speaker from the floor and give significantly improved dynamics. It worked for me.
