Re: Don't think so. ("High school physics" revisited)

12.149.8.201

If low frequencies can travel across the contact point, regardless of how small it is, there is no isolation.

Of course a spring must be adjusted to the load in order to create an effective mechanical low pass filter. Such a device, regardless of how large it is will *not* couple the low frequencies, it will isolate them.

I suggest reading Doug Blackburn's excellent piece on cone footers over at soundstage.net.
