link between speaker and floor

Be careful placing various "flats", "pucks" or coins underneath spikes. If you have hardened spikes connected to large, weighty speakers, the constant vibration can cause them to slowly dig or migrate through the metal "puck" and begin to bore into your flooring. I know that Bob Crump of TG Audio had a problem with this. Sean

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.
