Should I decouple my subs too?

Forgot to mention we have a suspended hard wood floor 

@noromance  

interesting idea I’ll look into that as well 

Thank you for your input. I will try both ways but I suspect de-coupling will be best as well

@millercarbon. 
Sound wisdom. I wish I would of thought of that. Thank you!!

I’m not familiar with Sub Dude but will definitely check it out. Thanks 

@oldhvymec. 
Very cost effective idea. I like it ! 

Thank you everyone for the advice. I really look forward to reading the daily posts. You all have taught me so much in the short amount of time I have been here. 

@ stereo5. Were you able to bolt the Gaia ll footers to your sub or just set the sub on top ? My REL S-510 subs only have 2 small screws on the end of each rail so the Gaia footers wouldn’t be able to bolt tight to the sub. I ended up ordering the OREA Bordeaux footers ( the style recommended by ISO acoustics) for the subs and Gaia footers for the mains and surrounds on stands. 

@phusis .  Thank you for the input. There is a hard plastic rail on each side of the subs. I have 4 subs. I figured there would be some type of rubber sole as well. There is only a thin felt like layer on the bottom. I believe that is why they are scooting around on me. I’m going to see how they sound with the OREA footers and if they don’t sound good I’ll send them back and try something else. Perhaps a thin layer of rubber under the rails. 

@stereo5,

The RELs have a curved rail on each side  with 2 small 4 mm machine screws on each end. These seemed too small to hold well so I didn’t even check if Gaia had an insert option that small. I would of liked to bolt the new footers on tight. The OREA footers are supposed to have a suction cup effect on the sub side so I guess I’ll see.
