Speaker Stands
By clinging I meant any vibration the speaker produces itself. But since the mass of the floor is much bigger than that of the speaker, these will have no problem feeding back into the speaker. 5) Some feel spikes are snake oil and have no noticable effect. They had another pair of regular LS50 connected to an Arcam A49, and I did listen to those. Well, I think an audio show it's hardly the place to draw conclusions regarding sound—unless you are looking for party equipment, that is.
When it comes to testing speaker isolation, it is not possible to place two speakers in exactly the same place at the same time, one with isolation and one without. I could feel low frequency pressure from the floor ( I don’t know if this is impacting the flat downstairs as well as “luckily” for me it’s empty). I have big rugs between and in front of the speakers but not under them. Anyway, I am not too sure rugs can do anything for this issue. The Seismic Podium is designed to brake the acoustic connection between the floor and the speaker, preventing the passage of deleterious vibrations both to and from the speaker cabinets.
Try to wiggle the speaker cabinet and at best you will just scratch the top plat of the stand. Spike feet do not have much capacity to absorb and reduce speaker driver-generated cabinet vibrations. Much of the vibration that causes a lot of distortion is higher-frequency, acute micro-vibration that you cannot really feel or readily detect. DBNeutralizer very effectively arrests these vibrations as well as a considerable amount of the more 'macro'- type vibrations. The Gliders also eliminate speaker-generated desktop speakers floorborne vibrations that can affect your other audio components.
The basic idea is to stop anything that the speaker is touching from vibrating. Speakers should particularly be decoupled from surfaces that resonate audibly or hollow surfaces which act kind of like an acoustic guitar body and amplify resonant frequencies themselves. Best solution ever was screwing the speakers tightly to the stands. Anchoring gave best result in deminishing cabinet resonance and general loss of efficiency due to speakers wasting energy to move back and forward slightly. In my case my old, very old, Nexus 6 stands were wobbly and nothing I did like tightening screws etc had much of an impact. I was having an issue with the bass on my LS50's on certain tracks at louder volumes.
1) You dont want the speaker to move or wobble, so you want them planted solidly. Using spikes whereby the tip if the spike goes through the carpet and contacts the actual floor actually couples it, not decouples it. For carpeted rooms, you may want this because a speaker sitting merely on the carpet surface allows it to float a bit. I also filled the pillars with sand and that reduced the vibration through the hollow aluminium profiles. I simply filled one stand with sand and used my hand to test how much it resonates compared to the empty stand.
Read many good reviews and had some beforehand but the initial fitting was painful and moving the speakers with them was quite a challenge…. The key with all Iso products is getting the weight right. There is an optimal weight range for their products and you should pick the appropriate item based on the weight you are looking for. You get a lot of answers because there is no such thing as decoupling.
