Is Spiking Necesarry?

I run ProAc D15's and use Herbie's Gliders with the stock spikes. Happy as hell - they slide with ease on the hardwood floor. Soundwise - a little tighter bass but you have to adjust the spikes to keep them rock solid to the floor. No movement at all. They go out of adjustment every month or so. 

Helps. The little Star Sound is good under speakers. Quality of stands make most difference but wood, metal or synthetic can sound better. 

Walk them over, I have that problem also! That is lift then up a little and with one side up move them over a little. I should have said with one corner down. Easier to do than to describe. I moved a gun safe this way once.

Herbies big fat dots under Thiels on hardwood floor over concrete has been best in my system.  Spikes the worst.
