Decouple Speakers

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.

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 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.

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 desktop speakers 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 a lot of answers because there is no such thing as decoupling.
