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 think this (spike) discussion is all over the place because we are mixing the applications. I always thought the spikes were provided for people who place their speakers on carpet floor. This way the speakers are, 1) more stable, and 2) they cut through the carpet and bond with the floor underneath. Hardwood floors; depending on sitting on a concrete slab or on hanging wood base, pose a completely different set of requirements. My most recent experiment of isolating the speakers from wood floor using damping blocks seems to give the least distorted bass. I could literally feel the very low octave vibrations in my listening chair with them sitting directly (on metal stands) on the floor. Those who actually like to "feel" their music under their seats and might prefer a solid coupling of the speakers to the floor...
@gdhal   I appreciate your question about the Herbie's gliders.  It is easier to move the spiked speakers with the spikes in the gliders.  I am still careful when doing so as I fear toppling over my speakers if moved carelessly.  

I just found my email correspondence with Robert Herbelin from Herbie's Audio Lab about the gliders.  Here it is:  
Placing a Cone/Spike Decoupling Glider underneath each cone and spike of the speakers would likely be beneficial, better isolating the speakers from the floor and any vibrations that would affect the speaker's performance. Many of our customers have found that the Gliders improve bass response and linearity, as well as other subtle sonic improvements throughout the audio spectrum. In addition, Gliders allow for easy repositioning of the speakers when needed. Between the three different options, titanium has the best potential to control the very high frequency, acute vibrations that tend to cause glare, though that potential isn't always realized; besides that, sonic differences between the three metals is subtle and system dependent. Due to the lower price, brass is the default recommendation; stainless steel is a good alternative to brass if you prefer the stainless steel aesthetic, and titanium has the greatest potential for controlling vibrations among the three (again, that potential isn't necessarily always realized and is somewhat system dependent).

Thanks. I'll give the gliders some consideration after I get my speakers set up in a week or so. I'm getting the Triton Reference and I will be spiking them to the floor (through carpet onto wood). Another concern I have with the gliders is that I imagine they raise the height of the speaker at least a half inch, maybe more. Not that a half inch is ultra critical, but many speaker manufacturers situate the tweeter at 41 inches (or thereabouts) because that is the typical ear level height in the seated PLP. Also, in my case I have some acoustic panels that were also placed with the height of the tweeter in mind. Still, the gliders do seem worthwhile and are not expensive (as audio gear goes) either.  
@gdhal  The Herbelins will let you return the gliders if they don't work for you.
