Black Diamond Cones for speakers?


will the BDR cones work for speakers? I am considering them as they do not look like they will scratch floors

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.
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.
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
You are going to have to trust your ears. I used BDR's under my kestral hotrods and they were not at all compatable. It may have been the combo of my parquet over concrete slab floor with the cones but what I ended up with was an annoying upper midrange exaggeration and a thinning out of midbass - not fun! It's too bad as they threaded perfectly into my speaker. Went to a vibropod-like material and was much happier. YMMV.
It only help if you use The Pit under the Cones for speakers application, otherwise, the speaker will move by itself and you lose a lot of the bass.
I use 'em on my KEF's and they seem to help a bit. Look real nice too as they screw right into the brass footer and spike.

Be sure to use the #4 cones as they are for heavier components. I agree with the first poster that they can still mark the floor -- although it's negligible compared to what spikes do.
Yes they work well under speakers too. Crush weight on each cone is 10000lbs. They look blunt on the tip but if you have a heavy speaker and you drag the cones under it, it will still leave marks on the floor.
