Addendum to my last: When Robert castigated "rubber type materials" one wonders if he’s referring not only to rubber itself but to things that bounce like springs and things that are not hard and rigid, things like Herbies Tenderfeet and constrained layer dampers that employ "rubbery" viscoelastic material as well things like bicycle inner tubes, air springs in general, bungee cords and squash balls. Because if that’s what he’s driving at then that puts a whole new light on things and demonstrates he really doesn’t gronk the whole vibration isolation thing and mechanical low pass filters in particular or even constrained layer damping and is in dire need of a seismologist.
Is Spiking Necesarry?
I like to move my speakers around a bit for to test how they sound, so I slide them. I have the Proac D48Rs, they are kind of heavy so with the spikes in it makes it tough to move them. I haven't consciously tested or compared the sound with spikes or without them. Does it make a difference?
