2" Dia Sorbothane Hemisphere Rubber Bumper Non-Skid Feet with Adhesive (4, 70 Duro)

I live in an old house with creaky hardwood floors. Due to space constraints, my turntable sits on a CD player that sits on large vintage floor speaker. I've spent the last year trying to DIY a solution for vibration and needle skips. Nothing worked. It was bad; anyone walking by or even moving on the couch would skip a record. To add to complication, I have a 3 year old that loves to run/jump/dance whenever any music is on. I bought these rubber feet in desperation and with little confidence they would work. Whoa. These are amazing! They resolved 100% the issues. I can play a record with no skips - with people walking around, dancing, even light jumping. What can I say? These brought my record collection back to life.

Now I know I am likely using this product outside it's intended use but for the purpose I have these did not work as I had hoped. My goal was to replace the leg system on a Bit Fenix prodigy case with something more stable. When these arrived the first thing I noticed was they are a lot softer than I expected, there is a lot of give in these. The result was that while the case now longer sways side to side, it does still shift some to the side when putting in USB devices using the front access. The system is more stable but still has a mushy feel to it as well. Another issue I found is that the material these are made out of is very tacky. This is good in the fact that the case does not slide anywhere. However it is bad in the fact that trying to pick up the case you have to overcome a stick down effect. When I pick my case up from my desk, which has a glass top, the top tries to come with it. These get the job done but for the money I would spend an extra $10 and get proper case feet.

The answer is, “I think so”, or maybe I want it to because I spent so much on it to help reduce the vibration and subsequent squeaking of my wood floors when the bass hits. I put these on my 15” subwoofer, and then I have a peice of carpet underneath that. It appears to help with the squeaking for most the bass, but it still squeaks for the consistent low frequency bass. I’m waiting for more to arrive so I can put it on my monitors and house speakers.

I have spent a lot of time with sorbothane both footers and stick-on pieces and I find that these footers are the best Sorb footers I have encountered. These are used for two different but related uses. Some are used under things like turntables to eliminate feedback from speakers through floors into the shelves and the turntable. If you have this problem, and some kinds of flooring are worse than others. We recently removed the carpet from our cement floors and installed ceramic floor tiles. Suddenly the peformance of a CD player deteriorated markedly. I used some old sorbothane footers and the problem went away. The other use which is less well understood in the US at least ( some British manufacturers seem quite up on it) is microphonics, i.e. the effect of vibrations from things like motors (in ttables and cd players) platters in ttables, transformers and possibly even AC cycling on the operation of circuits. Naim, a respected British hi-fi source is worth looking up for its discussions of these problems. Their stuff is good but expensive. Rather than buying new equipment I am retrofitting many things, amps, cords, cd players and speakers with sorbothane. I recommend using the heaviest grade of sorbothane, i.e. 70 duro. In fact a technical representative from the Sorbothane company recommended this to me. Adhesive makes sorb work better. The 3M thin double-sided tape used here is fine. However the seller has sent me three batches now without the adhesive and is not responding to my complaints. Since I have the industrial adhesive Lord 7650 that Sorbothane recommends this is not a big problem for me but it would be for others. The Lord adhesive is expensive, somewhat difficult to use and has a short shelf life after opened. I need it more for adding sorb to cases and the like. 70 Duro, 1/4 or 1/2 inch sorb cut into small pieces, (less than 1" on any dimension) is in many ways better than footers and cheaper. Constrained damping, i.e wrapping the top and side of the sorb in 4 layers of electrical tape adds a large level of improvement as well.

Frankly, I'm shocked at how well these work. I use them as turntable feet. I have an old Pioneer PL-518 record player. The rubber on the old feet disintegrated, so I've been trying to find a reliable way to isolate the thing ever since. I've got hardwood floors with a lot of give where the table lives. Basically any movement within 2-3 meters transferred. After adding the sorbothane hemispheres, nothing short of jumping up and down in front of it will cause a vibration significant enough to affect playback. Great product.

Stick like glue to floor and left black spot.

My title describes the issue I have with this product. I bought them hoping they would act as nice 'feet' for the bottom of my rather heavy speakers. It turns out they compress rather significantly even though I thought I bought the larger ones more capably of handling the weight. When compressed, they seem to adhere to the floor almost as well as to the bottom of the speakers, to which the adhesive flat sides are attached. That makes them almost impossible to move without lifting the speakers, even just to move them an inch or so. If you plan on attaching these to something you want to stay put and not have to move or adjust, then they will probably work quite well. Otherwise, I'd look at other rubber feet products.

These did not reduce any vibration or helped to decouple my TT. I bought the Nobsound springs and now we are talking!!! Look at all the stored energy in the 250Hz and down, highlighted in red, now look at the other picture, all that energy, that is bad for sound, is almost gone with the Nobsound. I am trying to show measurable data collected with REW, and I have no affiliation to either company nor I get compensated.

I have used these to raise a glass draining board base high enough to drain into the kitchen sink. The feet stick firmly to the glass and there is good resistance to sliding on the worktop below. There have been no problems over several weeks now. I am happy with the product.

These feet are amazing! I honestly wish that I had known about Sorbothane 10 years ago, because it would have solved so many vibration related issues throughout the years. After reading about all the different methods of isolating equipment, speakers and appliances from vibrations I bought a few different sets of Sorbothane feet to see if it was worth the hype and I am so glad that I did. I will definitely be a returning customer, and I have already started to recommend it to others. It is worth noting the weight ratings, and durometer ratings, of the products that you are looking at, because they are important for the end results. Also, they are sticky, but hardly anything to worry about. I could see them potentially harming wood finishes and things of that nature, but if you are planning to use them on something like wood you can wrap them in cellophane, or place a coaster underneath them to stop that. Overall, Sorbothane is an awesome product, and if you have any need for vibration damping there is a Sorbothane product that is made for it. I highly recommend it, and I will be buying more in the future.

Tout à fait ce que j’escomptais , très bien pour une platine de10k

Daughter had issues with tenant below here re bass bleed into his apartment. Tried the sorbothane isolators and so far no more complaints from tenant in the apartment below. ( The speakers involved are large monitors weighing approx 150 pounds ea using 15 in woofer in 8 cubic ft enclosure as well as a mid and tweeter horn in a seperate enclosure. The isolators work well and at a cost of approx 25 dollars per speaker they represent good value. I will be buying more to equip to equip my own speakers.

acheter pour le la Hifi meme au durometre 70 c est trop mou... mauvais conseil du vendeur (isolate it) qui m a d abord fait acheter un durometre 50 (hyper mou)... convient peut etre pour des machines à laver mais pas pour des enceintes....
