Lenco L75 pneumatic springs -

I'd like to give to my lenco 75 an isolation by four pneumatic springs ,
I'm from Italy, and I've only found on the RS catalogue the "FABREKA isolation feet " catalogue number is 688- 486 . Those pmeumatic springs could work, but the load is 45kg for 1 feet . My Lenco weighs 20kg . My worry is that with such load , bass extension could suffer a bit . I'm not deep in pneumatic isolations and related questions. Could anyone advise me what springs could be the better solution for my LENCO ? What could be the ideal load for my purpose ?

I'm sorry for my little english
 
This sort of idea isn't new I fitted isolation and leveling pads to a high precision industry machine tool in the London area in the 60,s .


There was systemic vibration causing changes to the carbide steel cutters in its cutting action . you will realize even 0.001 of an inch can cause £1000,s destruction to a vital machined component .


I think the company above is --Fabreeka a US division of US company

Stabilus.


For those that doubt that they existed that long ago-


Company - Fabreeka - Vibration Isolation, Impact Shock Control, and Thermal Break
 
This is always the problem when using industrial pneumatic components for isolation. A very high performance equipment rack using similar isolation has a monstrous slate shelf on top in order to lower the isolation frequency within a useful range.

The only sensible option is to create your own pneumatics, similarly to what Micro did for turntable plinth isolation in the 80s.

May I ask you why they shouldn't work ?


Without a sufficient load those are too stiff to offer any degree of isolation. You can just as well use some solid blocks.

You should start experimenting with very lightly filled golf cart inner tyres and see how well you like the effect and how loading changes the resonant frequency, isolation and perceived bass.
