Coupling vs Decoupling

@geoffkait - fair comment. I offered it not as a complete set of solutions but a starting point to understand the differences. Spring thing is good here (MinusK), at least under my turntable (~238 lbs with plinth).

I have my OHM 5000's on a homemade isolation stand. 4 aluminum cones with 2 granite slabs sandwiched with rubber and cork for dampening. I built a wood cradle around it so the speakers would be less likely to roll off. I have wood floors covered with carpet.

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

Always de-couple your speakers and equipment from a wooden floor even if it's carpeted, unless you want the floor to act as a sound board and ruin your bass.

Cement slab floor you can couple to.

@georgehifi  Agree with you about wood floors.  And coupling to a concrete slab floor can yield fine results... but, when this issue came up a couple years ago, I decided to decouple my main speakers and subwoofers and what I hear from that is greater clarity through the entire frequency range.

Why?  With decoupling, the energy from my speakers is dissipating across the carpeted floor rather than being transmitted into the slab underneath and then reflected back into my equipment rack and speakers causing a slight smearing and loss of detail to the sound.  It was quite definitive and after experimenting back and forth there is no going back to coupling for me.

The bonus benefit to the rest of the family is that my basement listening room is not rattling the upstairs when heavy bass is present in the music!
