- Geoff sez:
"The whole building is being shaken, especially upper floors. This is an obvious case where you would ideally want the entire building up on springs."
You mean suspended like a Linn turntable?

The practical solution is to isolate the speakers and your stands using a spring based solution such as the Townshend products, or for that matter Geoff’s springs. If you are feeling flush (very) an active isolation system such as the Herzan tables would also be very effective ... as others have noted this sort of interference is endemic and most audiophiles have never adressed it |
Geoff -- as far as I am aware no turntable suspension (barring ones such as the Dohmann Helix with an integrated minus-K isolation system) has a suspension that deals with vibration outside the audio range. Agreed the Linn is exceptionally floppy (i.e. high resonant frequency) but most are like that - my EAR has among the stiffest springs I know but again is no use against the sub 10Hz issues we are talking about here |
It does seem however that the OP has a secondary issue in so far as the room itself is exacerbating the sub-sonic issues. Bass traps will not help as they are also tuned to the audio range and cannot deal with sub 10Hz (think how large such a bass trap would need to be) I wonder if the issue is the floor acting as a resonator then mass loading the floor in the appropriate manner might break things up? Failing that as others have suggested an isolation fence could be a good idea -- many suppliers make such a thing but again it will not deal with the sub-sonic problems ... |
