Shocked removed spikes, used blue tack, what other non spike footer

I had an interesting  experience  recently. I was moving around my speakers with some pads to dial them in. They formerly used spikes and were in essentially  the same location. I removed the pads but did not reinstall  the spikes. A few days later I fired up my system and everything  from the bass to the treble sounded MUCH better in virtually  every way, and I couldn't figure out why. Turns out the pads  had some sticky glue on them that rubbed off on the speaker bottom and "tacky glue" them to the wood floors coupling the largest available surfaces together. Put the spikes back on and performance deteriorated  significantly. this was a great "test" as I had no idea what happened  so not a placebo effect. 

You will have more apparent bass when a very low velocity material is added to the equation. Slower than lead like all the rubber and spongy materials. Like placing your hand over your mouth and speaking. No highs no breath of sound mosly lows. The Shear velocity of the material chosen, geometric shape of the device..shape and speed of the material above and below are also of great importance. Your audio room will sound best with no right angles and corners as will every other area of your component high fi. Only a small portion of what takes place between 2 or more materials and their shapes. Tom

These speakers go down to 27hz and have nice bass even with spikes at low volume not only hear bass but feel it too, but no spikes just seem to appeal to me since there removal.Removing Cardas all copper binding post with speaker wire going straight into crossover brought back a lot of air and clarity. They do have ambiance rear tweeter with volume knob I had to adjust a little.( I've always kept it fairly low and still do). One problem with blue tak was piano, the sharpness and projection was muffled a little and not true, that is pretty much gone. This is not the way I planned to solve footer problem with rewire but it's helped a lot with piano and highs. It will hold me over till I can find solution to replace spikes. I still have caps to install so this will help too, this is a strange hobby. Still open to suggestion even if I had to do Gaia but damn for $600 it better be like a small component change not a tweek.

“No two spikes, springs, discs, cones or wood blocks sound the same if they are shaped differently, even if they are manufactured from the same material. As an example, pick up any two different brass products and listen to their performance as the differences are surprisingly ‘not’ close at all.”

What might prove useful to apply the seismic test to popular products like Herbies, Star, Gaia, Townsend etc and compare the results.
