Linn LP12 turntable

Another happy LP-12 owner here who lives in Ft. Collins and goes to Rick Duplisea for my TT work. Rick is also my Vandersteen dealer. I have grown my TT gradually over the years, sometimes leap-frogging over upgrades as funds allowed. The journey has been great!

Tomic , I was merely responding to posts by LP12 owners who mentioned it is susceptible to foot falls. To my way of thinking, that should be the last problem one might expect with a suspended TT. Which is why I asked. I am not the one claiming that footfalls are a problem; I’ve never owned an LP12, though my first real TT was an ARXA, back in the 70s.

Peace… F = MA and when a spring on any TT runs out of travel… things get ugly… the big Japanese TT are also susceptible on 2nd floors and suspended floors… even the mighty sota eventually runs out of travel….

Turntable suspensions are not designed to intercept foot falls, they are designed to isolate from the motor and higher frequency vibration. I used to have a AR which I literally could bang on the cover while playing and the tt would play on without skipping. But walk by it on the suspended floor would cause it to skip. Don't walk heavily by it while playing if it cannot be wall mounted. This does not need to be an issue. 

Let’s see. With what “higher frequency” did you bang on your AR? Most likely the frequency was 1Hz. A footfall is also 1Hz. So why shouldn’t the same suspension that filters out one one also filter out the other? What’s with F=ma? It’s true and always valid, but what did you have in mind? If you want to describe the force developed in a spring, don’t we want Hooke’s law, F= -kx? I’m assuming a well tuned spring suspension already. But of course a spring suspension needs to be damped; maybe that’s how a problem with footfalls might arise… if the disturbance sets the suspension into oscillation that is not damped.
