My tower speakers weigh 85lbs each. This sounds funny, but give it a try, it worked for me. I have carpet on a cement slab as well. The funny is I tried spiked plastic furniture grips that have adhesive I got at Walmart cheap. They have no problem holding the weight with one square on each corner. I move the speakers when needed for cleaning with furniture sliders under the spikes. Works slick. You could easily double them up for heavier speakers. The spikes isolate from the floor, yet stable. I would not have used this cheap solution if it had not improved the sound or were not stable. Or, you can spend hundreds of dollars not knowing just how good this works. :)
Footers under new speakers
Hi , I’m seeking advice regarding footers and/or platforms under my speakers. I purchased Tekton Double Impact’s and have heavy shag carpet and padding over a cement slab floor. House is 35 years old, cement is thick and well cured. I’m from that old mindset of spikes into cement and I am looking for an improvement. I’ve looked online at Gaia footers and Herbie's Studded Giant Gliders. I emailed Herbie’s and specifically inquired about the studded gliders alone on the DI’s over carpet. I asked about stability and was told the speakers were “ heavy enough “. Unfortunately I just set up the DI’s temporarily to get a little break in time. They are without any footers upright on my carpet. At 115 lbs the speaker does about zero to compress the carpet. I understand weight Vs footprint is abysmal but they won’t even stand straight. I’ll probably put the spikes on for a bit until I formulate a plan. But my first concern is that Herbie’s gliders alone are not enough and due to the minimum cost of the speakers I am struggling with purchasing Gaia’s footers and footer spikes. The seismic stands look exceptional, but I’m trying to be frugal. So I’m looking for suggestions like, gliders or dots with or without spikes on wood / stone plinths spiked to the floor. My goal is to try some sort decoupling (Gliders / Springs / Dots) AND eliminate the need of having to rely on the carpet being compressed. And yes I have cheap speakers and seek a cheap solution, so I get that limitation. Unfortunately I can’t afford Tannoy’s or Fynes to compliment my 180 watt tube mono blocs for at least a year.
