I misspelled "is" in my criticism of misspellings. Also, I have Vibrapods on things, although my 2 subs don't…they're on the floor making bass sounds so I allow them a pass to bend the floor with aplomb (!). Clearly I should not be let out of the house without adult supervision.
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?
