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

My floor standing speakers, monitor stands always came with spikes so I used them always, it's the way they were designed at least I thought. I know everyone can't do this because of there floor type, mine is hardwood over concrete slab. Bass, more natural tone( I'm a tone junkie)  gives the music a nice rhythm, may just be flavor of month but I'm really enjoying it. Highs maybe little rolled off, I just did it yesterday, maybe not as hifi, but no lose of information. Have other people experienced this.Can someone with my floor type suggest a nice reasonable priced non spiked footer, these are floorstander filled with shot so pretty heavy,maybe 70- 80 lb. thanks

If springs weren’t part of LIGO’s comprehensive and complex approach to seismic vibration isolation they would never have been able to detect and observe gravity waves, the amplitude of which are atomic scale. In fact, the observation of gravity waves, which occurred two years ago, was not possible for many years because the system was not sufficiently isolated from local vibration.

It is the same situation for audio reproduction. Sufficiently effective means of seismic isolation are necessary to avoid noise and distortion that low frequency vibration causes. Some obvious reasons for isolation are the relatively low natural frequency of the turntable tonearm and cartridge and the susceptibility of the CD laser assembly and the CD itself to external low frequency vibration, with the nanoscale laser and CD data in mind.

Almost all competent isolation devices and systems use springs in some form or another so the only reason I can think of why someone would disparage cryogenically treated springs is out of desperation and/or ignorance of physics and strength of materials.
There has been a peer review of the LIGO results. Was there a mis reading of the collected data.. was it gravity waves or still just noise? Tom

LIGO Receives New Funding to Search for More Extreme Cosmic Events

News Release • February 14, 2019

Grants from the U.S., United Kingdom, and Australia will fund next-generation improvements to LIGO

The National Science Foundation (NSF) is awarding Caltech and MIT


Since LIGO’s first detection of gravitational waves from the violent collision of two black holes, it has observed nine additional black hole mergers and one collision of two dense, dead stars called neutron stars. The neutron star merger gave off not just gravitational waves but light waves, detected by dozens of telescopes in space and on the ground. The observations confirmed that heavy elements in our universe, such as platinum and gold, are created in neutron star smashups like this one.

"This award ensures that NSF’s LIGO, which made the first historic detection of gravitational waves in 2015, will continue to lead in gravitational-wave science for the next decade," said Anne Kinney, assistant director for NSF’s Mathematical and Physical Sciences Directorate, in a statement. "With improvements to the detectors—which include techniques from quantum mechanics that refine laser light and new mirror coating technology—the twin LIGO observatories will significantly increase the number and strength of their detections. Advanced LIGO Plus will reveal gravity at its strongest and matter at its densest in some of the most extreme environments in the cosmos. These detections may reveal secrets from inside supernovae and teach us about extreme physics from the first seconds after the universe’s birth."

Michael Zucker, the Advanced LIGO Plus leader and co-principal investigator, and a scientist at the LIGO Laboratory, operated by Caltech and MIT, said, "I’m thrilled that NSF, UK Research, and Innovation and the Australian Research Council are joining forces to make this key investment possible. Advanced LIGO has altered the course of astrophysics with 11 confirmed gravitational-wave events over the last three years. Advanced LIGO Plus can expand LIGO’s horizons enough to capture this many events each week, and it will enable powerful new probes of extreme nuclear matter as well as Albert Einstein’s general theory of relativity."

@audiopoint, great stuff, keep it  coming. Fascinating subject.

Something tells me they’ll still be trying in vain to disprove Relativity in a 100 years time.

The artistic masterpiece of the 20th century.
