Black Diamond Cones for speakers?

thanks for the info, I'm most looking for something that will not scratch my floors and sound at least as good as the factory spikes, Prfont what MK? were you using

Mkaes, I can't say for sure. One set certainly was what they recommended for a tube pre-amp. These I had lying around. A bought another set of 3 just to complete the set of 6 for the 2 speakers, so it's very possible I was mix and matching 3's and 4's. If you don't mind experimenting or you can return the cones give it a try. Under my room/speaker conditions they were not a good match. Doesn't mean they won't do it for you.

I have brass cones presently & yes they'll certainly mark your wood floors. Haven't tried the BD's under my speakers although I do have pairs of 3's & 4's around for experimentation. Mainly I just want to suggest that if brass or aluminum is your cone of choice for best sound, then those little saucer-shaped cups placed under the spikes will alleviate the floor markings while not degrading the cone-coupling effect in my experience.
