4Pcs Audio Isolation Feet Load 400KG Anti Vibration Pads 40 * 20mm(Black)

I recently bought some new amplifiers, to make rear access easier and to increase airflow around the amps, I wanted additional space above the shelf, and between the amps. I searched for taller feet than what came stock, but about 20mm (3/4”) is where most top out. So I asked if these could be stacked and indeed they can. I bought two sets of four for each amp. This also required me to buy longer screws, but the feet easily accommodated the change. At first I even tried putting the manufacturer’s feet as a third set on the bottom amp (you can see the solid black puck on the very bottom in the second picture), but that made the top amp too high, so I decided on the original plan of two sets for each amp. I used 35mm (1 3/8”) screw lengths for stacking two pucks, and 50mm (2”) for three, my equipment required M4-0.7 machine screws, but you’ll want to match the size and thread for your gear should you decide to stack them. The included screws are stated to be (metric) M4-0.75 x 14mm, as they were too short for my purpose I didn’t try them. The feet work great and space my gear perfectly in the rack, this makes it easier to hookup the many cables in the rear (14 channels between the two amps), the extra space also allows for cooler running equipment which makes it last longer. I find these feet attractive, and an upgrade from the manufacturer’s original aluminum feet (though after I panted those black they also looked better). As it turned out, I probably could have gotten by with one layer of these feet, and the original feet pained back on the bottom, but my end result looks slightly better. So all in all I recommend these feet for single, double, and even triple height configuration. My personal (experienced) opinion is that feet of this type do not affect the sound quality of electronic equipment—like Amps, Receivers, CD/DVD players, etc. I also don’t think the small and fairly dense rubber ring is going to ‘decouple’ a subwoofer from the floor; the original feet or a specialty product like the (much more expensive) SVS SoundPath, will likely do a better job, but every situation and piece of kit is unique. This is an attractive, simple, well made product at a fair price.

While the installation could have gone smoother I'll chalk that up to me rushing. I used these to replace the legs on my MCS 6602 as it's been on a level shim with 3 legs since I bought it. My baby was level right out the gate, isolates well for the price and looks great with the black and silver of the 6602 as well. Adhesion of the 3M pads was a little meh but work with a little effort.

One issue, or surprise: the photo shows the isolators with 3M adhesive giving the impression you can stick these on to the bottom of your speakers. This is not the case. The other side of the 3M patch is rubber, so in the photo it is not really attached to the isolator, just sitting on it. Not sure the point of the adhesive as to use as shown you need to screw the feet to your speaker. I ended up using some double sided tape to stick the isolators to the speakers. Otherwise, seem well made.

Outstanding quality at a more than reasonable price point. The feet are not only attractive but are also substantially heavy. The optional 3M carbon fiber pads add additional isolation properties. The screws are M4 NOT M3. I advise using clear silicone adhesive under each foot and on the threads of the screws. This step adds additional isolation properties and prevents the screws from backing out.

A great value. We are replacing the artificial stanchions on the tops and bottoms of the base's on speaker stands with these. These are the same OD so they fit perfectly. These are well made and add a touch of class to your components .Arrived quickly and were well packaged. The 4 bolts provided are random so you may not be able to use them. Very pleased with purchase

These are a bit small. I needed them to get my subs from being directly on the floor for sound purposes. These didn't screw right into the old screw holes. So, one sub is just barely sitting on These feet. I ended up getting a foam footing used for washing machine and air compressors to cut vibrations. Much better amd cheaper! Up to you how to go but I wouldn't suggest these if needed for replacement speaker feet.

I've bought a few sets. I used mine on a Home Theater PC (HTPC) and CD player to 1) improve air flow and 2)prevent the cheap rubber feet from melting onto the furniture, as they are prone to do. The added benefit was making my PC look more like a piece of stereo equipment. (see photo's). While you can attach these with supplied screw, they do an excellent job just with setting the feet up and resting the component down - I have not permanently attached mine in any of my uses yet. I also feel my amp and breath a little easier now as the CD player has more clearance. Sonic improvements are subjective and too varied to make claims. You have to just try them on your own system. I would prefer a larger disk of 55mm or more for use with a turn table. At first I thought they might be a little too small, but after placing them, I think they are fine for the job. I would need a vastly more advanced system and environment before I feel a more advanced foot would benefit in any way other than esthetics. If you are looking for replacement feet for a piece of equipment that had more than rubber nubs, you probably want to look at a better item than this. But if you just need some space for improved airflow, or your little rubber button of a foot tore off or is starting to melt, or, you just want feet that look better than rubber nubs, this is a definite improvement. I bought a few sets, and will probably buy a couple more for a few other applications.

These speaker isolation feet work well and are easy to install. I put them on my homemade speaker and used some separate wood screws for that. I bought these feet because others didn’t seem high quality or didn’t look nice. They help a lot with vibrations and are nice and sturdy if screwed on correctly. My speaker is a little wobbly but that is since the board I used was slightly warped. 😅 They come with sticky rubber pads that go between the legs and your device which help quite a bit. Overall a nice, good value product!

Great quality indeed

They're cheap but I can't tell if they make a difference. At least the speakers sit off my timber floorboards.

Good quality, solid construction and an excellent replacement for the rubbish feet on my Compact Disc player, DAC and Amp. They came with screws which were unsuitable for the job, but I had a pile of 3M pads that did the trick. Worth every penny.

Screws didn’t fit my speakers so had to buy correct size, otherwise look good and work well on hardwood floor
