Spikes-Marble-Carpet-Wood Floors


My Snell CVs are about 100 lbs each. My hardwood floors are covered with a wool rug and pad. Currently I am using a set of aluminum Tiptoes I have had for about 20+ years.

The Tiptoes are not threaded they just sit under the speakers. I am not sure they are really coupled to the floor that well. They are going thru the rug and pad but is that enough?
I do have two marble slabs that could go under the speakers.

Should I place the marble under the rug? or on top of the rug? I am also wondering about gluing the Tiptoes to the bottoms of the speakers for a better connection.
Or should I just make some threaded DIY spikes and forget the Tiptoes?

hmmm. the spikes I have are 2 inch aluminum cones made by Tiptoes. How much difference could there be if I change to heavy expensive brass spikes?

Since the speakers are 100 lbs each I would think that the psi at the tip is very high.
Don't know, never tried aluminum. You could also try some inexpensive, about $10 each, German made steel cones that are sold by Musicdirect. They are not spikes though and have no thread. You can send them back if you don''t like them. Get the bigger ones if you decide to give it a try.
Iv'e received the best results from coupling the speakers to a heavy platform and de coupling the platform from the floor . Heavy dense cones always seemed to work better than the narrow spikes that come with speakers . If a cone is not threaded into something it will resonate more than if it is .
