Floor spikes for speakers?


I have Revel Studio 2 speakers with 2 SVS subs in a rather large, treated and carpeted room.  I bought the speakers with no floor spikes but I'd like to know what would happen to the sound if I put them on spikes.

Agree the Townshend Seismic products are the way to go if funds allow, but if your budget is more limited I’d recommend these two options that have gotten very good feedback here and offer returns if they don’t work out.  Personally I’d start with the Tough Nut cones unless you can only afford the Herbies Gliders.  Just a couple other options, and best of luck.

I have a  pad/carpet over a Tongue and groove oak  floor.  I got pieces of granite from someone who had redone their kitchen. The things they sell to put under spikes, can grind into your wood floor, so I tried the granite.  It worked okay.  Then I tried GAIA One feet and they made huge difference when used on the granite. That was with KEF Reference 5 speakers.  I have since moved on to some Sonus Farber Amati G5 speakers. I did the exact same setup and there is a difference, but nowhere the same. I’m guessing it has to do with the built of the speaker. The Amati’s are much better braced than the Ref 5’s.

All the best.

If nobody minds I’d like to, sort of, hijack this thread. What about spikes going into Black Diamond Racing discs on a wooden second floor?

I have a 100+ pound integrated amp, a streamer and a turntable on a Quadraspire bamboo shelved rack. 
If the recommendation is for some kind of separation between the floor and the rack what should I get?  I have, and love, IsoAcoustic footers on my Sonus faber Serafinos but I don’t think those will work under my rack. 
I appreciate your thoughts.
