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.
Great to hear all the advice to stand the speakers on granite or marble. Way to go guys. I have been advocating this all over here. But do you have a wooden suspended floor under your carpet or concrete. If you have wooden, go with the stone stands. If you have concrete, try to get your spikes to go though the carpet. If they won't move perhaps turn them out with big grips and replace with longer? |
If you have a concrete floor it's best to get the spikes through to that. But if the floor is wood or you can't or won't get the spikes through to concrete, stay with granite marble or other stone. Specific gravity is much higher than butcher blocks so they are less big and ugly for the same stability offered. I have a huge marble base raised on spikes for all my source and pre-amp gear and it looks great with its white and grey swirly colouring. Don't use any flexible support under the spikes, they just allow the speakers another layer of movement that will blur your soundstage.

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. |
@vinylvalet Not an opinion. Re-read my post. It is backed by science. Where is the evidence for your opinion? |
@michaellent Please read my previous post. If the floor is concrete laid on the ground the mass of the Earth will absorb all forces from the speaker via the spikes. The forces can only bounce back to the speaker if the Earth is moved by those forces. But as I say the Earth will not be moved because of the huge mass discrepancy between it and the speaker. It will simply absorb the forces. Flat dwellers in big modern blocks with concrete frames standing on piles driven into the Earth and concrete floors fixed to the concrete frames will obtain similar benefit. Putting the speakers on flexible supports that allow the speakers to move will cause far more distortion. Max has made a lot of money by convincing people otherwise. Although those with suspended wooden floors are his legitimate customers and there are plenty of them.

@joshua43214 I never said spike speakers to suspended wooden floors. Indeed I said don't spike speakers to suspended wooden floors. For the reason you state. But if, as I do, you spike speakers to a concrete slab laid on a screed in the ground the vibrations in the speakers caused by the music signal will be damped by the mass of the Earth which is 5.972 × 10^24 kg. If we take the speaker as having mass of 100kg, then the small movement in the speaker will cause a movement of the Earth that is 100,000,000,000,000,000,000,000 times smaller. I think we can take that as no movement. The statement near the end of your post is therefore correct, save that you can replace 'often' with 'always'. |
@mijostyn I am in agreement with you regarding relative masses. A concrete screed laid on good foundations in the ground will always be far heavier than any speaker as it is coupled to the mass of the Earth. For a concrete screed intimately attached to the frame of a large apartment building, again the mass of the structure will be much heavier than the speaker. |
