geoff, I didn’t know you are using a hammer on your super springs when music is playing :).
I like this one also:
>>>>>The rubber “bellows” in Townshend’s design overdamps the system. The rubber restricts the vertical and rotational motion, which doesn’t help isolation, it hurts it. The motion was much better (less resistance) in the beginning of his demonstration with springs only. Isolation is defined as ease of motion in a particular direction. The motion is obviously easier and less constrained with springs only. One advantage to the rubber bellows is it provides some additional lateral support for the iso system so that speakers with a high center of gravity won’t flop over. Having the framework to spread the springs out in a wide pattern is also to increase lateral support. I can do the same thing only better with four springs and a maple board. 🤗
This is why Townshend audio applies rubber. Actually it’s the air inside the rubber with a vent that damps the spring.

Plus the springs under load are constrained from ringing, like using your fingers to stop a tuning fork from ringing.It’s a good one.
