IsoAcousticsIso-Puck Series Acoustic Isolators (Iso-Puck Mini, 6 lbs max/Unit, 8-Pack)

I was skeptical but ordered a set along with a new pair of speaker stands. I received the pucks b4 the new stands so I placed them under my Martin Logan 35 XTIs on the old stands . I had been disappointed in these speakers since I purchased them. They just sounded lifeless and a bit flat. I have a large pair of Martin Logan towers in another larger room pushed with a NAD 150 a side amp and they sound great. Sound stage, instrument placement , 3D, everything is great about that set up. However I could not say the same for the XTIs in their current setup. After placing the pucks under the 35 XTIs, the speakers finally seemed to open up a bit. The sound was more enveloping, and the notes floated in air, now we are getting somewhere I thought. I received the new stands a day later. Along with the pucks, the new stands, I made new wires to separate the speakers a bit more to get the triangle of sound more accurate and gosh…. What a difference. So it may have been a combination of 3 different elements that finally brought the speakers to life. However as I mentioned I could tell a difference when placing the pucks on the old stands. They are not like having command strips on speakers/stands as far a stability. However the pucks do create a bit of suction between speakers and stands ( the new stands have glass tops). But the point is the pucks make your speakers disconnected somewhat from the stand. If you have an inexpensive set of stand speakers you may not tell much difference. However with a more higher up the line set like the Martin Logan’s all I can say is the speakers finally sound “alive”. They are $100 bucks and are returnable, so what do you have to loose other than a couple hours of goofing around with your stereo? There are worse ways to spend your time.

Everything is brand makes his great and this is no exception. These are perfect for small monitors in a tight space.

I have a pair of KEF LS50 on my desktop at home and the vibration transferred to the table was really excessive. My first attempt to tame the reverberations was by placing Auralex ProPads, which helped a lot. However I found them esthetically challenged as they tend to accumulate a lot of dust and grime and are very hard to clean due to their rugged and porous surface .So I tried the ISO-Pucks: Installation was a breeze as there are no screw or complex mounting instructions that needs to be followed. One just have to place 3 or 4 pucks under each speaker, make sure the placement roughly symmetrical and that the speakers are stable. It is always possible to move them later.There is a marked reduction of vibrations transffered to the table. It's not a 100% isolation but it's better than the ProPads and when I place my hand of the table surface when playing loud I can barely feel a tiny amount of vibrations.So yes, it definitively does the job of reducing vibrations.Does it make the speakers sounds better? Yes it does. It's not a transformation but the sound does get clearer and more defined. I definitively recommend them if you have a similar speaker set and placement problems.Is there anything that could be improved? Well, there is no height adjustment so the speakers will be at a constant height and always parallel to the table surface. However IsoAccoustics does offer other products that enable height and angle control but I decided to try their pucks instead of the speaker's stands.Does it look better? I attached the before and after pictures so you may judge for yourself. I personally think that the change a positive one and it also allows me to clean the table under the speakers.

Iso-Puck helped speaker vibration & cleaned up midrange sound

Although a bit pricey, these are well worth it for heavier components. I researched a long time & never did find a better deal using similar technology.

I bought the iso-puck mini, which worked well for my KEF LS50 meta speakers for my computer desktop.The sound did improve slightly (10% or so). The speaker had more natural tone and resonance particularly in the bass and guitar music. Any music that significantly vibrated the speaker was significantly improved.The key to this device, in my view, is fairly simple physics. This device substantially reduces the surface area in which the speaker can transfer its energy to the speaker platform. The result is that that energy is released to where it is should: the sound. My KEF LS50 meta sounded "purer" and definitely had more natural tonality especially in guitar and bass.These also look nice and has the natural stickiness to both the platform and the speaker, so these isolators grab the speakers fairly well.Nonetheless, I would also say you can probably buy far cheaper alternatives that would have the same effect. These seem to be rather basic plastic/rubber items that improves the fundamental physics in how the speaker transfer its energy, and I bet many cheaper alternatives can do exactly the same.Pros:1)Improves the speaker sound by reducing the surface area in which the speaker can transfer its vibration energy, resulting in more energy to the production of the sound itself. The sound is more real with more natural tonality especially in bass and guitar music. But it isn't a great difference.2)Has natural stickiness (like rubber stickiness) to both the speaker and the platform, and that makes it more difficult for the speaker go off-axis.3)looks nice, which is a plus and perhaps worth the premium price.Cons:1)You can probably find similar efficacy product for far less money.

These are the best isolators I have ever used. I put the mini pucks under my Dac and transport. The difference in focus is amazing. I’m buying the larger76 model for under my mono block amps. Also bought the Isoacoustics Gaia lll’s for my Wilson Sasha’s. These are not inexpensive, but the result is worth ever penny
