hardwood floors and spikes

http://www.audioadvisor.com

A product called Quadraspires, $19.95 for four. Located in Isolation components.

I use them under my spikes on hardwood, I also placed two way removable tape on the bottom and stuck some black felt, so I can easily move them around without scratching the floor.

Tape from Lowes in painting supplies, Various colored felt from Michaels.

Works like a champ.

If the floor is a wood joist suspended type you might want to put the speakers/spikes on a harder, more inert surface like granite or for a cheap fix some concrete flag-stones from home depot at about $5 per. I found the wood floor acted like a resonating board for the bass frequencies and found the concrete helped. (best results though were with the concrete spiked and the speakers on aurios, but that was getting elaborate.) Stay away from rubber based footers as they compounded the bass-boom tremendously. (at least in my case.) Good luck. Oh yeah and don't forget the wool carpet.

Ok here's my two cents,,,,,,,,literally!

I had the same problem a few months ago with my Klipsch speakers. I found the cheapest solution to the problem. I put a penny under each spike. The whole tweak cost 8 cents and it didn't affect the sound at all.

May sound kinda cheesy, but hey it worked!

good luck

Cone coasters by Sound Anchor. Nice looking stainless, with a small divot for the spike and stuff on the bottom so you can slide them around easily when you need to.
