Stack Audio Auva's
They have it figured out. Completely blew away the Gaia's which were light years better than spikes.
I have them on my Wilson's, REL's, and ARC preamp.
Best to you!!

+1 Townsend Podiums. Tried spikes and footers but the Podiums were far better. What to expect … clearer bass, faster transient response, better imaging. Why? It’s simply physics. Spikes alone increase rigidity by coupling the speaker to the floor/room while the podium isolates the speaker from the room. Coupling increases structural/room resonances which can cause bass reinforcement and cancellation, smear transient response, and affect timbre. Decoupling by spring damper principles used in the podium decouple the speaker from the room and set the resonant frequency at approximately 3Hz, above which resonance effects will not be audible. The Podiums are sold for different weight range speakers to assure spring damping is correct for the mass so the resonance frequency is appx. 3 Hz. So it is not surprising they work because the design simply physics. Highly recommended based on my experience. |
@jsalerno277 +1, isolation and decoupling are key. |
@mojo771 I'm always fascinated by this topic because i also have my speakers on carpet over concrete. My speakers came with spikes and i do not use them, principally b/c i know that my housing pad (and the area i live generally) is very hard soil that carries vibrations a long way. i can sit on my flagstone patio and feel the vibrations from passing trains that are more than 5 miles away! So i assumed if i coupled my speakers to the concrete i would be transmitting those vibrations into my speakers. At present i don't use anything under my speakers but have been considering acoustic isolation devices and am grateful for this thread and the many who have recommended various products which i'll investigate. W/ respect to the article @sargonicuse provided i intuitively agree with the author's points but note that the author also works for (or did work for) AV Room Service Ltd whose products are designed for isolation/decoupling, so naturally he is against spikes. i found this article more convincing on the topic, not b/c of the spikes argument but because Jim Smith (RIP) was a highly respected voicer of systems and his argument is that speaker placement will affect the sound far more than coupling/decoupling--but in general he seems to argue against spikes unless they have an appropriate interface with the floor that [decouples?] them. FWIW. https://www.psaudio.com/blogs/copper/spiking-your-speakers-whats-the-point?srsltid=AfmBOooli76fyTL8CjTXiZAz6CaVUwHte3tcUjgGZfgI5aL_EfyyAkxo#:~:text=Quite%20simply%2C%20using%20spikes%20as,that%20the%20bass%20is%20tighter. if the link doesn't work just Google "Spiking Your Speakers-What's the Point and you will see Jim's article as published by PS Audio.

@mojo771 Solved for $12.56: https://www.supplyhouse.com/Bluefin-VPE-400-E-V-A-Anti-Vibration-Pad-4-x-4-x-7-8. These provide 100x the isolation than the $1500 Center Stage2 LS Footers that came with my VSA Ultra 55s. |
