Spikes and hardwood floors.....what to do?

When I had spikes under my speakers, I found the IsoClean larger pucks for hard wood floors sounded best. Previously I used nickels. I once had such heavy speakers that I needed to put two nickels under each spike.

Have a look at the Superspikes on this page. It's an interesting product that may or may not be suitable for your purposes.

Thanks for all of the great suggestions!

I used the superspikes on an older pair of Energy C-4 speakers with great results. Fine product, easy to use, not bad looking either.

There is a guy on *bay site that I have dealt with. Just do search in home audio/speakers/spikes. He sells just the little discs for the spikes to set in. Different finishes/plating as wel. I like the black chrome.
