1.25" Dia Sorbothane Hemisphere Rubber Bumper Non-Skid Feet with Adhesive (4, 50 Duro)

Used these under my JBL LSR305 monitor speakers on a glass table and actually had a genuine jaw dropping moment. Obviously a glass table is not ideal for monitoring however that's my only option right now and after experiencing these I will be using them on whatever surface my monitors sit on, stands included to achieve proper frequency levels for mixing, recording and producing.Test 1: Speakers only on glass table. Used palms and fingers to feel the area next to the speakers and under the table where the speakers sit. Results : Clear, obvious and strong vibration/humming of all low frequencies resulting in a false sense of bass throughout the table. Used Britney Spears' "I Wanna Go" as the reference song as it has strong bass frequencies from start to finish.Test 2: Placed 4 of these under each speaker (round side up supporting speakers) still sitting on the glass table. (Did not remove adhesive on flat side) Results : I kid you not, a 90-100% reduction of the same exact false low frequencies at 90+db. I'm in disbelief that these little black crescent shaped squishy "bumpers" could absorb and dissipate that much bass before it reached whatever surface the speakers would sit on.Test 3: Set my JBL LSR305's on these bumpers again (round side up adhesive peel away still intact) which in turn fit perfectly on each point/leg of my ISO Acoustic L8R155 speaker stands. Results: 100% reduction of any humming, buzzing or vibration of bass frequencies traveling through the table.You can normally feel the bass traveling through the ISO Acoustics however it's severely reduced when the speakers have these bumpers in between them and the stands resting points.Conclusion : I can't believe this material isn't used in every monitor stand or promoted more as a decoupling method for speakers. I'm not sure how the one reviewer here did not experience these results. I tried Blue-Stick (Tack) and the results didn't come close to this. Incredible and well worth the $20+. While I also recommend the ISOAcoustics as they give your monitors a much needed lift to ear height and an apparent 80-85% bass reduction which greatly improves and tightens bass response and boosts the clarity of the mid and high range, I wouldn't hesitate to place my monitors on these bumpers alone, which cost a 5th of the price of the ISOAcoustics and in my opinion decouple and dissipate/absorb low misleading bass frequencies much better. However the ISOAcoustics give an unmatched floating/raised height effect which is extremely beneficial. The reaction I had the first time listening after placing my speakers on the ISOAcoustics is subtle compared to the reaction these sorbothane bumpers gave me. If the ISOAcoustics are out of your price range these bumpers placed on a regular or DIY stand would have the same decoupling effect.Note: I have not peeled the adhesive off of the underside because I'm hesitant to have adhesive glue stick to the ISOAcoustics resting points but I can only imagine the decoupling effect would be even greater if the 3M paper peel (reflective material?) was removed. It also might not make a difference as it is extremely thin.That said, combining both the Sorbothane bumpers with the ISOAcoustics L8R155 like I have gives an incredible kind of mind blowing result with more credit going to these bumpers than the stands. Extremely satisfied.

I wasn't sure just how much this would help isolate a hard drive that was noisy. In fact, this is the noisiest hard drive I have ever heard and I have heard a lot. (Thundrbay G raid). The armature in the drive really makes a racket that transfers to the large desktop upon which it sits. So we put the drive on these isolation feet and I was very impressed by the amount of improvement. Noise transmission through solid objects such as a desktop can be much greater than people might suspect and this does quite an excellent job of decoupling the drive from the desk. This will do an excellent job of isolating fan motor noise that is vibrational, but you cannot expect it to reduce general fan noise (while noise) caused by the actual air flow of the fan. That requires a noise control box or some other different form of control such as absorption. This would do well to isolate fairly light objects according to their rating system. This is a great value and I recommend it. For reference, I am a full time professional audio and video engineer and have designed and built a number of professional audio studios so I have more than a casual understanding of noise control.

I was looking for spacers to put between my audio components to allow heat to escape. I have my receiver, line conditioner, cable box and center channel all on top of each other because that's what the space calls for. The Rubber bumpers are soft... not like a rubber bouncy ball at all which is what i was expecting. They are very soft and gel like. They probably do reduce some vibrations like a Gel Pad and would be great for under a record player. For my application, they are overkill, but do nicely and look good doing it. I can understand the price more after feeling them.

These work really well! I am very happy with them. Put them on my 3d Printer, and barely any of the vibrations transfer.

These work very well. I have a pair of Vanatoo T1s on my desk, and the entire desk would vibrate a lot when listening to anything with any bass and a moderate volume. Laying your hand on top of the speaker, there was quite a bit of vibration as well,m even though the speakers are quite heavy for their size.After applying these the vibration in the desk and the speaker cabinets is significantly reduced. I performed some A/B tests by alternately placing the speakers on top of some steel blocks, then back on the isolate it pads and playing the same section over again. I have no way to measure the vibration, but from feel I would estimate that it eliminated 90% of the vibration. Although I can't really hear it, it must also be helping the speakers as well, because they no longer vibrate either.Recommended.

I've been using Sorbothane in hifi and home theatre setups for a number of years. It is an excellent vibration damping material that can help prevent turntable skips and tube feedback or isolate speakers from a building's structure.The hemispheres are best suited under turntables or tube amplifiers where skipping and feedback can be an issue.The flat disks are best for speakers where you don't want the bass to go through the structure of a building... trust me, your neighbours will thank you. The effect on sound within the room is negligible.This is one product I can recommend to anyone.

Conosco il sorbothane da quando avevo il giradischi Oracle 3a serie, di questo materiale era fatto il tappetino sul quale appoggia il disco.Questi piedini sono ottimi per isolare dalle vibrazioni gli apparecchi HI-FI in quanto assorbono le vibrazioni e le neutralizzano, trasformandole in calore. L’eliminazione delle vibrazioni funziona a doppio senso, cioè vengono assorbite anche quelle generate dall’apparecchio.Una accortezza da avere sta nella scelta accurata della dimensione dei piedini in base al numero di questi che si decide di usare.1) non è obbligatorio usare i soliti 4 piedini, in base al tipo di apparecchio ne possono bastare 3 (se piccolo) o 5 e più se è largo ed ha una superficie estesa. Ad esempio, nel caso si vogliano mettere sotto un giracd, un convertitore o qualsiasi altro apparecchio con la base inferiore larga, potrebbe essere utile posizionare 4 piedini ai lati e 1 o più al centro tra piano di appoggio ed apparecchiatura. Fate attenzione alla conformazione dell'apparecchio.2) controllate bene il range di peso consigliato dal costruttore. Prendete il peso dell'apparecchio e dividetelo per il numero di piedini che pensate sia utile utilizzare. Poi scegliete la dimensione di piedini che ricadano circa nel mezzo del range consigliato.3) I piedini sono autoadesivi, quindi prima di applicarli definitivamente fate delle prove senza staccarne la pellicola protettiva dell'adesivo.Un pò di tempo perso a tavolino vi farà fare la scelta giusta che vi gratificherà con ascolti migliori.

Yo las he comprado para darles este uso. Los bafles pesan unos 13 Kg. y he usado 4 esferas para cada uno. Llevan poco tiempo de uso pero hasta el dia de hoy el material se comporta perfectamente. Quedan bastante chafadas, pero no van a más, estan igual que el primer dia. Aislan las vibraciones casi al 100 % y he notado mucha mejora en el sonido. El único problema que les encuentro es que son bastante caras.

These things are really good! For my Tannoy Little Red speakers (by no means little), I've been using granite cutting boards placed on thick open-cell foam and that worked very well. However I swapped the Reds for the larger, heavier Tannoy Cheviots and they were too much. The bass was booming from the cupboards they were placed on. So I took a punt and bought theses sorbathene things. They work brilliantly! 4 under each speaker, straight onto the cupboards, and almost no vibration is transmitted. Bass is now tight and strong and the whole sonic image is focused. 22 pounds VERY well spent. Totally recommended!!!
