Caster Wheels vs. Spikes


My Tekton Double Impacts came with caster wheels, which made them very easy to move and reposition. They are sitting on probably fake wood floors in my apartment. They sound great now, but I can't help but wonder if I'm leaving SQ on the table by not having them on spikes. Some people say I must use spikes, others (including Erik Alexander) say wheels are just fine. They are super heavy so the wheels are not easy to take off. I want to make sure it's worth doing. What are your experiences and thoughts?

I assume by fake wood floors you mean suspended floor, in which case the spikes are generally not recommended. Castors are better isolators.

Oh, you are SO losing out by using casters! The difference is OBVIOUS. No true audiophile would use casters! Once you hear spikes you will NEVER want to go back! 

Hey, wait! I put casters on the Vapor Audio Joule White speakers! Nevermind.   ;) 

No one here has figured out the most important variable between spikes and casters. 
Have soundocity make outriggers for you that will fit your caster wheels to position then get the screw in from the top threaded spikes once finally positioned. 
Swiveled plastic wheels are working great for me on hardwood. So easy to position depending on where I’m at in the room. I lock the wheels with than pointed out at the corners, give the speaker a little shake to hear the wheels lock and it feels pretty solid if trying to move the speaker.
Great way to experiment with the sound/position!  And fairly cheap. 20 some bucks for a set of 4
