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

I have to say that these really work. They are the perfect size for my larger bookshelves. They would work well with any sizes bookshelves I would think. I'm using them with KEF R3 Metas and Philharmonic BMRs in a nearfield setup. Decoupling makes a huge difference in sound quality and dispersion. Not really cons, but some observations that I wanted to share. 1) It's difficult to move the speaker that these are under after they are set. You have to pick the speakers up to move it and the pucks fall all over the place. ISOAcoustics needs to make a frame you can drop these into so it's not such a pain to move them. 2) The bass seems odd when you drop these under your speakers. Not really flabby, but a little flat. I need to try other placements. I'm about 2 feet away from the back wall and the speakers are set on the wooden and metal Monoprice Speaker stands. I didn't have this issue before.

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.

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!

These are outstanding and represent a good value. If your audio equipment is not very sensitive you may not need this, it's not for everyone. But, if you use a tube amp on a desktop or have speakers on a desktop, or just have an equipment rack that doesn’t isolate each level, then these are a great way to achieve isolation from vibrations and represent a major improvement over foam pads. I have a tube amp on my desk, it runs headphones and speakers that are on separate stands. The tubes are very sensitive. Typing, or setting things down on the desk create audible responses. A foam isolator or stand would not be appropriate or fit under the monitor, but the iso-pucks fit and effectively remove any vibrations from being transferred to the tubes. For major shocks like setting things down or smacking a mouse, it would also conceivably prevent the tubes from being prematurely worn out. I used these on studio monitors as well, back when I had ones that sat on my desk. They would cause the desk to vibrate and create audible measurable noise. I got isolation foam and used a vibration sensor to measure, I wasn’t satisfied because it was only about 70% effective and the desk still had noticeable vibrations and the speakers actually shook more then when placed directly on the desk which potentially hurts sound quality. Ideally you would want a speaker to not move at all so anchoring it to the ground via spikes can separate it and help all the energy go into moving the woofer instead of shaking the case, which is what I ultimately did. However, I also tried these pucks and they are the next best thing. They have rubber on the top and bottom and their movement is directional (place them logo facing front.), so they isolate and anchor to some degree. They reduced vibrations in the desk by over 90%, to the point where it was hard to tell or measure, but when touching the speaker itself with the sensor, the speaker also had less movement which was unexpected. They are better at isolating than foam, very short to allow a lot of flexibility in placement, and offer some amount of anchoring for speakers for when spikes and separate stands aren’t an option. Overall it’s a modern solution to an old problem and best in class while being more flexible, with measurable improvements. That being said, a lot of systems won’t benefit much from it alone, the audible difference can be very situational. There’s cheaper things like foam that might do what you need and better things like spiked separate platforms/stands. You just have to use your judgement if there is a place for it in your setup. I find they are flexible enough that almost any system can get some level of benefit from them. There is a weight limit. So check the gear you plan to put on these before buying. This brand has several classes for different weights though I find this class to be particularly useful for desktop applications. They are also durable. My desktop amp pushes close to their weight limit and yet they work as good now as they did 4 years ago. When relieved they return to their original height and are indistinguishable from ones that had remained in the box during this time.

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 don't often leave reviews. These are amazing and I feel like a fool for not having used something like them for years. 7" studio monitors in a home office setup, nothing pro... as soon as the mini pucks were 'neath the speakers... "oh!". Much better (MUCH) imaging in the mids and low mids thanks to the isolation these provide, I suppose.

I approach basically every isolation product with skepticism. There's a LOT of trash out there that does absolutely nothing, yet still has rave reviews from placebophiles. Plainly, these work as advertised and I'm impressed. I'm currently using 4 pucks under my Schiit Freya+ preamp. It's a tube preamp and I have a few sets of tubes that are particularly microphonic, and thus good testers. The Freya sits in a typical budget wood/metal audio rack. With the Freya sitting directly on its shelf, you can clearly hear the sound of objects tapping on the shelf and metal supports being amplified by the tubes. I tried your typical sorbothane feet, same thing, no improvement to isolation. I finally decided to try out some mini Iso-Pucks with a great deal of skepticism. I'm equally surprised and happy to report that these actually work as they're supposed to. I can wail on the shelf with a pen, my finger, any objects producing a wide variety of tones, nothing gets amplified by the tubes anymore, dead silence. I'll be purchasing the full sized pucks for my monitors in the near future.

Great audio equipment isolation. No vibration, improved performance of Tube Phonostage and network switch

It doesn't make difference

El producto funciona de la manera que se supone que lo debe hacer, la idea es aislar el altavoz del lugar en el que este colocado para que el sonido que produzca sea el suyo exclusivamente, sin resonancias, acoples o vibraciones de muebles estanterias, pies de altavoz o cualquier sitio donde esté colocado que pueda ensuciar el sonido. Para mi merece la pena al 200 % porque hace justo eso, aislar y que el altavoz suene como el fabricante lo ideó sin nada más, ahora bien si tus altavoces ya de por si no suenan bien, estos soportes no van a hacer magia y de repente vas a tener un sonido increíble, hay que ser realista.

Absorbeurs utilisés sous des enceintes bibliothèque qui sont posées sur un bureau, le son est immédiatement transformé ! Totalement indispensable !

Fatti davvero bene. Solidi e con un ammortizzatore molto efficiente. Con i precedenti monitor avevo gli ISO 155 ma li ho venduti perche avrebbero alzavato di troppo il mio nuovo punto di ascolto, così ho provato questi. Alla fine li ho restituiti perchè non hanno migliorato il mio punto di ascolto. Le mie nuove casse suonano davvero bene e nonostante le diverse prove che ho fatto, senza i disaccoppiatori suonano meglio specie nel lowend. Comunque IsoAcoustic è sempre un marchio di garanzia e qualità.

No creía que mejoraría el sonido de mis monitores pero vaya que me sorprendió mucho. Son más pequeños de lo que imaginé pero soportan muy bien mis Focal Alpha 65 EVO. Al escuchar música se nota más claridad en las frecuencias y la imagen estéreo, además de mayor profundidad. Re-mezclé una canción y vaya sorpresa!!! Cuando hice la comparación con la antigua mezcla todo suena mucho mejor. Más claridad, profundidad y la imagen estéreo más abierta. Suena como si ya estuviera masterizado (sin la ganancia de volumen). No puedo hacer más que recomendarlos. De verdad estoy muy impresionado con ellos.
