I have a concrete slab floor with tile. The speakers Usher Be-718 (85lbs ea speakers and stand) are currently setting on the concrete tile on hard rubber supports. Any recommendations like changing the supports to spikes and a Herbie or Cone/Spike Decoupling Gliders or stay with the a hard rubber Herbie product. I really don't think this hard rubber pad I'm using is doing anything. ( Ps there is a large 13x14 wool rug in front of the speakers.

Hi, Mav52. Herbie's Audio Lab does not use rubber with any of our products. Rubbers have resonance and reverberant issues that are detrimental to loudspeaker performance, usually affecting linearity. Rubber's contravibrational enerergies also are too slow to deal effectively with much of the very high-frequency acute microvibration that causes a lot of the glare and grunge in music.
We have several dBNeutralizer-based products appropriate to support your speakers. I suggest considering four Giant Fat Gliders under each stand in place of the rubber feet (not under the rubber feet). dBNeutralizer, a loosely crosslinked silicone-based formulation with barium sulfite and silica fillers, is a compliant yet very firm material formulated specifically for the absorption and blocking of acoustical energies. Gliders can be used on bare or carpeted floors, bringing out more of the best sonic potential of the speakers and allowing easier mobility of the speakers when needed. With Gliders, you should get a deeply linear, better-defined bass along with subtle improvements throughout the audio spectrum.

(If you already have spikes to use, a Cone/Spike Decoupling Glider under each spike is an excellent alternative, or Threaded Stud Gliders threaded into the bottom of the stand in place of spikes. With a superior isolation/decoupling approach, there's really no need for spikes.)
Between each speaker and stand, I recommend using four Herbie's Audio Lab Square Fat Dots. Isolating the speaker/stand interface is always most essential to bring out the best potential of the loudspeakers.

thank you Steve. I think I might order 8 of the Cone/Spike Decoupling Gliders if you think that's the ticket.

Is there any difference in isolation between the Giant Fat Gliders vs the Cone/Spike Decoupling Gliders.

Giant Fat Gliders have more dBNeutralizer "beef" and thus more vibration absorbing and blocking ability. Though smaller, regular Cone/Spike Decoupling Gliders are very efficient and effective and should be more than sufficient for your setup, especially if using four Square Fat Dots between each stand and speaker.

I've had excellent results using the Giant Cone/Spike Decoupling Gliders (four per speaker) to isolate my 500 pound per side speakers from a hard floor. I got the titanium plate versions since they're supposed to sound the best.
