Coupling vs Decoupling

I’m new to this forum and have been doing much reading. I’m aware working with the room and equipment can produce dramatic changes in sound. One topic I’m lost with is coupling vs decoupling. When, where and how to apply each method to produce the best outcome?  

My current system is KEF R900 towers with matching center, R600C and surrounds, R300 and a pair of JL E112 subs flanking a Sony A1E TV.  The room is a bonus room approx 24’ x 14’ with all centered on the 14’ wall. 

Currently the towers are equipped with spiked plinths and subs sit directly on the carpet with their OE feet.  Any feedback about how to best manage acoustic vibrations and when/where to apply coupling or decoupling methods is greatly appreciated.

I appreciate the responses so far. 

@hifiman5 - the floor is a second story carpeted wood floor in a bonus room above the garage. The TV and components sit directly on a wood console, that is a leftover from pre-system days. Perhaps this is a great reason to upgrade!

@blueranger - thank you for the video. I’m very surprised the difference it made, even viewing from my iPad. I have looked at IsoAcoustics products recently. I’m curious which products and applications could produce best results. Do you have any personal experience with them?

@geoffkait - the idea of a combination to produce ideal results makes sense and is intriguing. Do you have personal experience with a product you’d recommend?

Thank you all for your response and input.  I've just begun the online search to learn of all the available products and options.  I'm interested to learn more about IsoAcoustic and Townshend platforms and pods.  Does anyone have experience or feedback about these companies or products?  Would either of them be a good option for my KEFs and JLs?

@geoffkait  - Mass on spring isolation for speakers happens to be a hot topic these days with at least a few Mass on Spring solutions available to audiophiles, including those from your humble scribe.


"From your humble scribe"....... Can you pleae elaborate?  I am very interested to see and learn more.

Thank you audiopoint.  That’s a lot to unpack. I’m intrigued by your product and look forward to hearing more. 
I’ve taken your advice and reached out to KEF, IsoAcoustics, Townshend and Stillpoints directly. I’m eagerly looking forward to their responses.
