Simply not correct. Credo is wrong. Its representative says speakers need to be isolated from vibration by being decoupled. But this involves supporting them on a system that allows the speakers to move. The movement of the elements in the speaker that transmit sound creates forces upon the the frame and fixed structure of the speaker. This allows the speaker body to move in response. Newton's third law I think. If the speakers were spiked to something solid that movement would not occur. The movement of the speaker body moves the mounts of the sound transmitting elements that moves the sound transmitting element. This movement is not driven by the music signal. Accordingly it smears the sound for the listener. This will be heard mainly as inconsistency in the sound stage.
Spikes on tower speakers
This is my first post here, just getting involved in the earlier stages of serious stuff. I recently bought a pair of Piega p4L MKll speakers. They sound great, at least according to my perhaps unsophisticated ears.
My question/problem: The speakers have spikes on them that cannot be removed because the previous owner glued them to the base. Becaue of the spikes, the speakers are very unstable on the carpet in my listening room. I need something that the spikes will go into so that the speaker towers will be more stable. So far, neither plywood nor small metal speaker spike pads have worked. Am now considering carbon speaker spike pads and hockey pucks to get the spikes into and then a bigger base, such as wood or even granite/marble.
I would greatly appreciate any suggestions that would solve this problem.

@clearthinker Just your opinion. An old audiophile myth. |
@vinylvalet Not an opinion. Re-read my post. It is backed by science. Where is the evidence for your opinion? |
@clearthinker My ears. Also, the Credo video also shows some compelling scientific measurements/evidence. The science you cite is correct. The audible effect, if any, is outweighed by other science (energy transfer). If you want to couple your speakers to the floor, that's fine by me. |
@vinylvalet. @clearthinker is absolutely correct. Any movement of the speaker enclosure is distortion. This occurs mainly in the bass. Put your hand on the speaker while playing a bass heavy number. That vibration you feel is distortion. The floor to the speaker is analogous to the tonearm to the cartridge. The floor has to absorb the energy transmitted by the speaker without reflecting it back. Admittedly, some floors are better at this than others but, that is a floor problem not a speaker problem. All Speakers producing bass have to be anchored to the floor. Any other approach is absurd. The OPM should take this into account and anchor his speakers to the floor. If the spikes are too short to make it down to the floor then you need longer ones. If you feel uncomfortable doing this yourself find someone that is not. I would gladly do it for you if you live in New England. |
