Maybe you didn’t get my memo. Stability is the enemy of isolation. Isolation effectiveness occurs with the great ease of motion, not with the inability to move. Yes, I know what you’re thinking, “But aren’t audio components and speakers like musical instruments?”
Just confused
Hi I am fairly new to using high quality audio equipment. I have assembled all of the gear I want for listening/enjoying the music. Of course it’s only a matter of time before you ask yourself “What if?”. I understand that room acoustics matter so I am off trying to implement acoustic panels - some good relatively consistent advice here. What I struggle with is the subject of vibration control/isolation ... the advice from the community is not very consistent. The floor in my listening room is slab cement with ceramic tiles on top. I have Avant-garde Uno speakers (with spikes since that is they way they came), REL subs (rubber feet) and effectively an unbranded equipment rack (with spikes). Are spikes what I should remain with for this kind of surface? Does it make more sense to decouple the speakers and rack from the floor with some kind of isolation device? Should I be replacing the current metal spikes with “cones” (or other device). Should I use the same device for speaker and rack? I just want to avoid shelling out a bundle of money for something that may turn out being a negative. Thanks in advance for your patience with my naive questions.

Room acoustics is pretty well established and accesible, making going from bad to at least decent not all too difficult. Vibration management, on the other hand is poorly described in audio both by manufacturers and hobbyists. I give credit to GK and some others for actually explaining the physics normally, though. If I were you, looking for direction, I would seek advice from Jim Smith, who is a setup professional and former Avantgarde expert and importer. http://getbettersound.com/index.php |
I have some mag Lev feet on the way for my subwoofers. Everything should be here Monday. Are you able to post pictures on this forum? Anyways I think isolation is the only way. There’s a company from England that does it with magnets https://solidairaudio.com Google a guy named Max Townsend. He’s got some really good videos on YouTube about how his products work and the benefits of isolating your speakers from the rest of your home |

Depending on how one sets up the system, however, springs can provide isolation in 2 of the 3 rotational directions. Value added! 🤗 The reason compression springs are excellent at isolating moderate to heavy components is because they are very stiff in the horizontal directions, providing much needed lateral support. Add air suspension, inside the coil and underneath via a cantilever. The vertical becomes very stable and very isolated, With a single bag for all 4 corners. It can be adjusted with a simple nitrogen charge. Close to zero, harmonics, then. The bag could be centered under the cabinet, henged X 4. Silicone mount the four fulcrum points. Spring work/help, you just have to dampen them too, along with henge points.. OR Hang it like a heavy bag on an inverted, spring, they are adjustable too. Regards.. |
