Monosaudio Audio Isolation Feet 4 Pcs 40x15mm Turntable Feet Replacement Speaker Feet with Non-Slip Rubber Rings/Adhesive/M4 Screws for Audio,Speakers,Subwoofers,Amplifier,Turntable,DAC(Silver)

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.

I used these to replace spikes on my floor standing speakers, which I did not like on the ceramic tile floor. The included hardware did not fit the threaded holes in my speakers, so I made a trip to the hardware store for the proper bolts. Adhesive pads were not included with the set and there is no change, nor did I expect any, in the sound quality of my speakers.These DO make nice looking and sturdy feet.

These footers look good and seem to do a decent job. They offer two methods of attachment.

Used them on my Polk CSi5 center. I replaced the silicone pads I was using with these. They are not attached to the speaker, the speaker just rests on them ( I did not want to drill holes into the speaker). My speaker is planted to my table and it does not slide at all. As for the sound quality, no difference to me. I just wanted something nice to elevate my speaker off the table that looked nice. Very solid, extremely sturdy, not cheap and they give you hardware to attach feet to whatever you want. Great feet for the price. Highly recommended!

Good quality feet, included adhesive pads provide great option if you don’t want to drill holes in speakers. The included screws are useless, the feet aren’t threaded. If you need these for mounting to receiver/turntable/etc., you will need to obtain nuts. Hole from bottom of each foot is deep and narrow, so having the nut on the underside would be hard to tighten. You will have to mount by inserting screw from bottom, so make sure you have appropriate size screw length and nuts that won’t interfere with interior of receiver (etc) cabinet.If you get stainless steel screws that are about the size of the hole in the foot, you might be able to self thread. Or if you have an “awesome set of tools,” use a tap to thread. Dude.

Price is fair and they look good. One ring fell off during placement of a power amp. Very difficult to pull and replace on heavy equipment

I had a very annoying vibration in my Polk audio subwoofer. I was certain it was related to the hard plastic feet that were on it. I went into sticker shock when I started pricing isolation pads that were big enough to fit under it. This was an inexpensive solution that worked perfectly and they look good as an added bonus. The included screws did not work for me as the old feet were just nailed on. I used wood screws to install these feet. The whole process took about 10 minutes and now the vibration is completely gone. I'm very sastisfied with these feet.

Looks like a well made product, although I wonder about the size of the rubber O ring, and if, over time it will compress and no longer absord vibrations.

Well made and make your components look great !

Muy buena calidad

I bought these because they are advertised as including double sided adhesive pads. The adhesive pads included with my order are single sided with textured black rubber on the other side. They are useless for my intended purpose of sticking the feet to the bottom of my pre-amp to provide ventilation space between pre-amp and power amp.

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.
