Floor spikes for speakers?

Decoupling reduces vibration which lowers coloration. I decouple all my equipment which allows mechanical energy to turn into thermal energy. I started with my subs and heard the biggest difference. Still very present but tighter less boomy/extended. I use AV Roomservice and love them. Disclaimer all setups are different.

@mojo771 , give a look @ Stack Audio products. I live in an 100+ year old home, & I found the 70 series worked best under my LaScala's. I tried almost every material but, the Townshend podiums which are special order. I had the funds & ready to pull the trigger, but these S/A 70s did the trick. They have a no questions asked return policy. The glasses in my cabinet which is 30' away stopped clanging.  

I will second the mention of Stack Audio AUVA 100's. You can get them with small carpet spikes. They are fantastic.

Isoacoustics Orea footers would do well under your components. I have them under my Boulder 866 integrated amp. 

@wswright20 , Wow ! What a beautiful room you have. Did you consider spikes under the feet ( pods ) of the Townshend Podiums ?
