Hardwoodfloors and Spikes

I'll second the spikes (or cones) and coasters from Sound Anchor. A great side benefit of the coasters is that they are a felt like material on the bottom and I can move my Europas and Sound Anchors easily on the wood flors to try different speakers positioning. This at almost 100 lbs total weight.
Rubber sounds---umm,let's see----oh yes, Rubbery!

Conecoasters from Soundanchors @ $14.00 each work great for me with spikes on my oak floors. My rack weigh 600+ lbs. with gear, if I went straight to the floor with the spikes the points would be visible in the basement! I also use Orchard Bay points, & pucks under my speakers. The only time I ever used rubber was under down firing subwoofers to keep them from moving around.

Some people who have tried both spikes and softies prefer one and some prefer the other. As I remember a lot of those who use rubbers, utilize them in a slab sandwich - more fun, less attractive. Spikes appeal to me only because their purpose is to better inhibit speakers from rocking. The energy used in rocking is information lost.

I used to have a house with hardwood floors; thought the discs 'n spikes worked quite well, but never tried squeezable alternatives.

I will second the opinion about the nickels below the speakers.

I use pennys below my spikes. It works quite well, However depending on the wieght of your speakers you might want to spring the extra 32 cents and use nickels.

The Copper in the pennies is softer and a really heavy speaker with spikes can drill there way through a penny over a few months. I just colored mine black with a Jiffy marker as not to stand out.

Cheers,
Nick

All, who have opted for the conecoasters, from Sound Anchor, made the right choice. I also use them under my Dynaudio stands. The felt pad underneath the conecoasters allows me to slide the speakers for easy placement.
