link between speaker and floor

I second John 1's comment. Aurios Pro's are a major improvement under spiked speakers, either on a wooden floor or carpet.

I'll second Sean's comment--especially with regard to soft change. I had a pair of ProAc RS2s on Target RS4 stands (filled with sand) and the four spikes on each Target punched through the pennies I used in no time. Wasn't even that heavy... Figure 75 lbs for the stand, mebbe 30 lbs for the speaker, 25 lbs of sand for 130 lbs total distributed over 4 spikes is, er... about 32 lbs per spike. With a sharp spike tho', the pressure on the point gets *big* very fast.

Thanks for all the helpfull feedback, now i have some good ideas to pursue.

I use hard white felt under the discs. Hard and thin as possible.

I also like Aurios under floor standing speakers, I am using Aurios 1.2 model. If you want to change tone slightly warmer place wood block under Aurios or thin dense cork pad. This sounds much better to me vs any cone system I have used. I am sure the Aurios Pro's sound even better for a higher price.

To easily move heavy speakers go to pet store and get 1" wide 6-8 ft nylon dog leash and cut off metal clip, slide under speaker and use as two handed sling to carefully lift from behind (like movers do).

If you want to stay with cones/spikes many companies make various cone discs/pucks to protect surface.
