Trying to understand the Townsend podiums better I wonder how many here have actually measured how much their speakers are resonating. I would want to know that going in I think. Also why wouldn’t speaker vibrations dissipate in a concrete floor ? What makes them come back up into the spike?
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. Cheers , Mike B.

@goose , Yes , I’m wondering where this will end up and probably where you are. I totally trust Hilde45’s opinion, and he’s tried everything. But I need to travel the path of finding out. If they were domestic and not $1800, I would have just purchased them. Question, my speakers footprint will work on a size 3, but per center of mass to center of platform I might need bigger. Any experience with that? FWIT my son in laws handle is BOB, he was an F-18 pilot and now a T-45 instructor. In the movie it meant Baby on Board. That’s not even remotely close to what it means. 😆 Respectfully, Mike B |
See the video: https://www.youtube.com/watch?v=dW9-r83IvhI&ab_channel=TownshendAudio Here’s a guess at one question, @ronboco While spikes increase the coupling that helps to stabilize the speaker and direct energy into the floor, the mechanical connections are still two-way.The speaker vibrates, that energy is transmitted down the spike into the concrete and then some of that energy will inevitably reflect or be conducted back up the spike and into the speaker cabinet. Even a concrete floor despite significant mass is not a perfect absorber of vibration. It can still resonate and transmit vibrations that will then conduct back into the speaker via the spikes, potentially introducing coloration or distortion to the sound. The question becomes: how much vibration is happening and is it audible. That would be a very specific question – about hearing, perception, and the spikes, speakers, and floors involved. |
