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?

I have lowther fideleo speakers on a slate floor & have found that spikes on top of ball bearing footers work well. I don't move them once in the sweet spot though. That would truly be a pita. The combination creates a nice soundstage.   
Spikes helped tighten up the bass for me, just a tick, on a pair of Cantons on padded carpet.  Once the spikes are installed, watch out for your feet.
@randy-11  - or... buy electrostatics or Maggies - problem solved (and a lot of other problems are solved too)

Or other problems are created. It's literally a double edged sword....... I wanted to like Maggies, but their dipole configuration does not work in my room. And it's not because their is not enough room behind them....
