+1 for Millercarbon, he is correct about springs. I tried stone, spikes, no spikes, Herbbie's gliders and the Townshend podiums sound the best. Get the cheap spring option he mentions and try them out
What is a good base for speakers
Fussing with setting up a new system in basement. My vintage ADS L710's sit on original stands that don't have fittings for spikes. As the stands sit on a carpeted floor, they rock a lot (no pun intended). I'm thinking of some sort of base to settle them down. Looking for suggestions of a material appropriate for stability - any experience with wood butcher block, granite or slate cutting boards as a base? More DIY than expensive. Thanks for any suggestions.
