Centre Speaker Decoupling
Cone/Spike Decoupling Gliders, Threaded Stud Gliders, and Little/Giant Fat Gliders will help to hold the speaker cabinet and baffle steadier, reducing distortion. The idea is to keep the baffle that the speakers are mounted to as motionless as possible for the cones to render the music most accurately. I have had the speakers stood on spikes directly on the carpet with the spikes going into the floor. The floor is concrete block and beam construction, with foam insulation on top and then a layer of chip board, so effectively a stiff suspended floor. I found that as the Wilson Benesch Vectors have downward firing ports that placing them on the Oak platforms improved the bass, detail and depth. The goal of spikes under your speakers is to decouple them from the next surface.
A suspended wooden floor will re-radiate late and spectrally incoherent - a temporally and harmonically unrelated growl, all the time. Microphones are not spiked but rather are decoupled in most instances in order to accurately capture the original pressure changes without interference from external sources. You are again mistaking the pressure changes at the diaphragm of the microphone with the pressure changes caused by the reproducing equipment.
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 floorborne vibrations that can affect your other audio components.
The stands weigh around 25Kg each and use the usual large spikes on the base plate. A reduction in vibration could be felt by feeling the cabinet wall with my hand. 4) Still another site contends that decoupling is preferred because a coupled speaker allows the vibrating floor to transfer its energy to the speaker, causing the speaker to vibrate more.
I ordered and tried a huge number of isolation/vibration reduction materials and footers to test out when doing the turntable platform, and nothing came remotely close to the spring-based design of the Townshend pods. With the springs under the base, it just killed these vibrations. Stomping around yielded virtually imperceptible results hand on the base, and showed almost nothing on the measurement app. Now if the room is dead (think carpeted floors, etc. then coupling can help kill the resonances from the speaker and stand. So spike the stands so they anchor into the carpet, and couple the speaker and stand. Which I assume would be the best as the only thing moving would be the cones, no vibrations, no resonance, no transfer of energy from speaker to stand or floor or console etc.
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 desktop speakers a lot of answers because there is no such thing as decoupling.
