Mechanical jacks under the floor are a cheap, stable option but will not solve the real problems of your stereo. You can effectively build a suspended floor under you speakers with the speakers mounted on springs and the suspended floor further mounted on springs and then the wooden floor. Mine are blocks of laminated pine, built like mini butcher's blocks, 600mm x 450mm x 100mm. this arrangement isolates the speakers from the floor and the speakers from each other. Spring rates depend on the weight of the speakers for the first set of springs and the weight of the speakers and blocks combined for the second set of springs. Depression of each set should be around 25 - 35 %. This is achieved by reducing or increasing the spring size and or number of springs. Nobsound springs are good but more expensive than others on Amazon. Total cost for my set up was approx $120.
Isolation Advice Needed
Hello, moving to a new home later this summer. The new house has suspended floors (wood over crawl space). No noticeable bounciness or floor deflection but so far I've lived in homes with concrete floors, so walking on the floor was subconscious activity. In the new house my steps are louder when I walk. So not sure what to expect when I setup my system in the new house.
I have all tube system housed in a Salamander rack. Any forewarning of unwanted vibrations creeping into the system and ways to mitigate them is greatly appreciated.
Current System...
Rega P6 (Audiomods Series VI/Shelter 501)
Aesthetix Rhea Sig. tube Phono
Graaf GM-50B Tube integrated
Wilson Benesch ACT Speakers (with Gaia II feet)
Best Regards
