IsoAcoustics Iso-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.

Iso-Puck helped speaker vibration & cleaned up midrange sound

Works as advertised!

Let's be real, for 8 chunks of rubber, the better part of $100 is kind of nuts.But they work. Using these, I no longer hear resonance/vibration from my desk when playing low bass.

This product order was actually a mistake at first. I just got a new Rel sub and didn’t realize that Rel doesn’t recommend noise dampening tools such as Isoacoustics. I already own the Iso stands so I decided to put the Isopucks on my stands. Holy holy smokes! I’m now a huge Isoacoustics fan! The isolation and clarity is off the charts!! I now ordered the next size up for my huge Emotiva center channel which already has a Isoacoustics stand too! I know it’s overkill and you would be just fine with just the stands but experiencing the pucks with the stands will floor you! So I took my noise dampening tool off of my Rel and I dont recommend isolation pads with just that line of subwoofers. I do have a Klipsch subwoofer with the Isostand and I highly recommend the Isoacoustics 200 model for that but not Rel. Rel designs their subs with the exact height measurements for proper bass. I HIGHLY recommend yhe Isoacoustics Isopucks and stands for all other speakers and subwoofers!! It’s like you get 100% of all the listening and zero unwanted vibrations!

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.

I used these for a relatively small set of expensive speakers (Eve Audio SC203) sitting on a small wooden shelf. The shelf was badly amplifying the bass rumble when using my turntable at a listenable level. I put 4 mini pucks under each speaker (the pack comes with 8) and immediately the rumbling disappeared, even at high volume. The difference was so big I started to laugh. What an investment. I can now use my speakers to their full potential.

Added these guys to decouple our speakers from our studio desk. Added noticeable clarity in our situation. Would like to try some for our studio sub. Would highly recommend if you are wanting some.
