hardwood floor and speaker

When I removed the carpet from my listening room a few years ago I used the carriage bolts with pads as P_Nelson suggests. Inexpensive and effective.

Try these, I too have wooden floors and these great.

I use pennies under the spikes to protect my wood floor, as suggested by George Short of North Creek, the designer/manufacturer of my speakers. 8 cents, out the door. John

I got a chuckle out of this one!

I use brass discs intended for use with spikes. They have an indentation in the center that the spike sits in, and allows you to slide it a little if you need to toe the speakers in or out. The discs are about the diameter of a quarter. They haven't scratched my flooring (hardwoods).
