While there's something to be said for making the floor shake (and there's bass shakers for that I believe), there's also something to be said for not shaking the room below me when I get in a bassy mood. These are currently being used for a Klipsch on the smaller side, but based on their make I believe they could easily handle much heavier. The remove any rattle but still let the bass thump. I've read about the tripod configuration being more balanced and I may try that, but I don't think it's necessary. Happy listening!

These little guys are super heavy duty. All machined aluminum and heavy rubber. These are designed for decoupling a subwoofer from the floor. This can help tighten up bass response. These are incredibly high quality and should last a very long time.

Trying to fight with physics to get both better acoustics in my room while also reducing noise is always a losing battle absent a complete home renovation.But for me, I don’t have the budget, nor do I OWN a home, to invest in complete solutions, so I try out my fair share of noise reduction and acoustics-enhancing products.With any quick fix, I don’t expect wonders, but these 4 little feet have subjectively improved my experience with one of my subwoofers (a Roku slim wireless bass). It’s crucial here to note that the subwoofer I got these for is a front-facing (or front-firing sub): it does NOT fire downwards like many others, and I think that’s important for why these feet work for me.In any case, they feel solidly designed, like rubber with a little gap and some…I don’t know, hard plasticy material? I imagine all this is to get that “decoupling” effect that I’ve heard of, but I also don’t want to overstate what this is: it’s essentially four “feet” to place under the subwoofer.NOTE: the instructions say to remove the current pads or “feet” on the bottom of your subwoofer before placing these relatively flat isolation feet underneath the four corners of the subwoofer. For me, this was surprisingly easy, as I just had these four plugs already on my subwoofer that popped right out, and then the flat bottom of the subwoofer sits perfectly on the surface of the new isolation feet.Like I said: I don’t expect miracles, but I have this sub in an echoey room with hardwood floors and drywall. While a rug underneath might do the trick, I don’t have that option here, so these really helped lift this off the ground and reduce the vibration transfer to the floor (which, in my case, made everything sound muddy and louder than wanted until I put the isolation feet on).Overall, I’ve written way too much about what essentially is a solid set of isolation feet. Again: this won’t necessarily blow you away if what you’re looking for is complete noise reduction, but it is a noticeable improvement for those of us who can’t renovate our living spaces or get something way more expensive. So in my view, this is a value because it does essentially all that you can do with some quality isolation feet, and if you’re able to add a rug or carpet, even better!And bonus: these can be helpful for other things like noise machines that rattle on desks, and other speakers that transfer vibrations on hard surfaces, though they are hefty so they are better suited (and more economical) for frontward-firing subwoofers.Hope this helps!

During a move one of the original rubber feet on my HSU vtf-15 was damaged. These pads are a perfect replacement. They appear to be extremely well designed and made. Sounds Addicted states they can support up to 200lbs and I don't doubt it. My HSU vtf-15 weighs 123lbs and these pads have no issues at all. I tested using the intro for Edge of Tomorrow and the worm hole scene from Interstellar and no unwanted floor rattles/vibrations I was getting before these.Overall I'm super impressed with these isolation feet. I need to see if Sound Addicted make isolation pads for bookshelf speakers, if so I'll be picking those up also.

I was a little bit skeptical about the concept of subwoofer isolation pads, and especially whether these things were worth $34 (the price as I’m writing this review). After installing them, I feel like they are well worth every penny. I parked them under the subwoofer, and the sound instantly became cleaner, with crystal clear bass response at all wavelengths.I feel like the engineering of these pads is subtly clever. Construction is very basic - they are hard rubber pads with thick metal sleeve retainers. The proof is in the performance, though. I had the subwoofer on rubber feet before, but now the sound is dramatically better to my ear.

Easy to use and gives a nice lift.

Well built for the low cost.

As advertised, the rubber was harder than expected, and it's essentially just a rubber piece with a metal ring outside. You pay for the looks, but maybe any normal rubber chunk could do the same.

Well made and they do the job for a fraction of the cost.

They totally work! However, the issue is getting them under the subs. I have a Nakamichi sound bar with dual 8” subs and getting these placed is difficult. There is no adhesive to help them stay in place, I ended up using some double sided tape in order to get placement correct. But they ABSOLUTELY dampen the vibration and I can now turn the bass up.

They're sturdy, they're well packaged and well made. They work to isolate ground thumping as far as my non-audiophile ears can figure.Weird thing only being able to buy one set in a single order. I have two subs so I cheated this by making two separate orders within a minute of each other. Sorry sellers, but that's a stupid restriction.

I was confused when I bought these... thinking that they somehow attached to the bottom of the subwoofer.. but they simply are put on the floor, and then the subwoofer is placed on top of them. They DO work... as the neighbors below me are no longer complaining!

Sound isolation is critical for subs or even hi-fi speakers with big woofers. All that vibration effects your sound and if you play vinyl records, can really be a nuisance - if you've never heard low frequency rumble creating feedback through a phono cartridge, trust me it's awful.These are very simple, yet nicely made and they function as they should. While there's no adjustment (like you might want to level a turntable) these should also work well to isolate components from vibration, not just subwoofers from the floor. At $34 these are a pretty good buy, really. Audiophiles pay much more for products that are only slightly better. Sound Addicted has a great line of products - check them out!

These are surprisingly good isolators. I’m currently using them on a hefty Klipsch 15” sub, but eventually I’ll get my custom 18” setup built and tuned, then these will serve that house-shaker. Anyway, these are clean and everything I could have hoped for in sub feet. Pricey, but it makes sense once you hold them.

New computer case came with hard feet that alongside the power of the computer ended up being able to shake the whole desk while under high cpu loads that had fans past 50 percent. Acoustic isolation pads did a wonder of keeping vibrations isolated from the rest of the desk including any other free standing devices like other wireless chargers etc. Size of the pads helps them fit alongside the whole feet of the case and their the perfects quality of rubber to keep in place while also quieting the device itself from sitting against the hard wood desk. Over all extremely satisfied with these things, no complaints and pretty good value for how well they work!

Works like a charm. I’m in a townhome and my neighbor said ever since I put these on, he hasn’t felt a thing.

These are very solid and well-made. They do an impressive job isolating and minimizing vibrational transfer to the surface below. I have these under two different sets of subs now and would definitely recommend.

My husband, who is obsessed with his speakers, had never thought to try these but now can't imagine not having them. He says they open up sounds that he couldn't hear before (clarity) and he no longer runs in to the vibrations he was getting from the cabinet it's sitting on. Great addition for any audiophile.

I actually got the Sound Addicted subPods Subwoofer Isolation Feet for placement under my integrated amplifier, rather than my subwoofer, since my sub already had good isolation feet. These isolation feet really look and feel well made and they are easy to install. Good thing was that since these were taller than the original feet on my integrated amp, I didn't need to remove the original feet to add these. I left those as they were and installed these and now the amp sits a little higher, and I am assuming it is less susceptible to vibrations caused by my speakers and sub. Overall, these subPods are very nice and I recommend them.

OK, any review of audio components MUST describe the associated equipment, acoustic environment, and source material -- otherwise, there's no way for a reader to know whether a reviewer's conclusions apply to the reader's own system.In my case, I power a pair of Harbeth speakers with about $20,000 of T+A amp, preamp, & DAC. My room is 14x17, with treated walls (wall treatment won't matter much to the lower registers we're talking about here).The weakest component is my MartinLogan Dynamo 600X, a downward-firing subwoofer that runs about $600. It's a pretty good sub for the money, but not in a class with the rest of my recently upgraded gear. It does, however, have significant output down into the low-20Hz region, and includes a room-correction DSP that smooths over acoustic anomalies. Overall, the sub does what it's supposed to do in this smallish room, but lacks the transparency and speed of 4-figure alternatives.A couple of important considerations that greatly affect how a reader should interpret what I find:i) The floor is carpeted, which serves to partially decouple the sub from the frame of the house. So I don't have much problem with mechanical resonance. If anything vibrates in the room, it's because of acoustic (as in "through the air, not the floor") coupling.ii) This is a 35-pound downward-firing sub with 10-inch driver and non-removable feet. The designers apparently wanted to be sure that the driver is a specific distance from the floor. That's understandable, since changing the size of that gap can have significant acoustic and mechanical effects, even changing the load on the driver.iii) The subwoofer's DSP has already smoothed out most of the frequency-response raggedness created by room modes (standing waves that are related to the dimensions of the room). Prior to installing these feet, sine-wave sweeps detected just a few tiny anomalies, all of which were above the sub's crossover.iv) Oh, and my Harbeths start to roll off around 45Hz, so the sub is crossed over at 35Hz. Integration is pretty pretty smooth -- something that took quite a bit of experimentation to ensure.OK, that's all done. Now here's the beef:When I inserted the pads under the feet of my sub, raising it about an inch from the floor, there was virtually no difference in the smoothness of the frequency response. The one or two little bumps, narrow in frequency range and no more than maybe 3dB, did not change. The biggest difference I heard was an increase in power around 25Hz, where this sub normally struggles. This was a broad increase, maybe half an octave, and about 6-12 dB in amplitude. Significant, but not apparent in most popular and acoustic music, which mostly lies above 40Hz and, other than "big beats" and super-deep synth notes, rarely dips below 30Hz.A well-configured, good-quality sub will, however, improve the sound of upper registers, especially male voice. The feet made no difference in this regard. Vocals and mid-bass content from bass guitar, kick drums & floor toms, or grand piano sounded pretty much the same before and after.One surprise, though, was that the room rattled at around 30-35 Hz AFTER inserting the feet. Without the feet, there was no rattling. The most likely reason was that the increased low-end response triggered a room mode. That is, this rattling was the result of acoustic effects, not mechanical coupling with the floor. It would be interesting if I reran the room-correction process with the new feet installed, but that's an involved procedure. If I do find the time to do so in the future, I'll amend this review.OK, a couple more important things:- My source material was quite varied: acoustic jazz, deep-bass club, big-explosion movies, large-scale orchestral performances, classic rock, modern pop, and even "serious" academic electronic. (Hard to find bass content deeper than Morton Subotnick's "Silver Apples of the Moon"). This included the famous Flim and the BBs "Big Notes" album on dmp, which reportedly had content down to an astounding 8Hz. I listened on CD and high-res Tidal, both through my T+A's $6000 DAC and integrated disc transport, and on DVD and Blu-ray disc played on an Oppo disc player, but decoded, again, by the T+A DAC.One of my biggest surprises was the build quality of these feet. They employ a mulit-layer floating design, similar to that of many of the pricey audiophile alternatives. In fact, I find it absolutely amazing that these feet cost only $35 for FOUR! If someone had just handed them to me without any other identifying information, I would have guessed that they'd cost ten times as much. No exaggeration.So bottom line, how did they work? Well, all things equal, they didn't do much for my system. I was first inclined to give them 2 or 3 stars. But I ultimately bumped my rating to four stars for several reasons:i) I had already resolved most of my mechanical-isolation problems through the DSP room-correction built into my sub (an i...

They do what they say they would.

really straightforward product here, not a whole lot to say other than it is easy to install them and they work well to raise up the subwoofer and soften the vibration against whatever surface it's sitting on.

I got these so I can use them on my JBL 1300x Sound bar system. However that Sub is on a carpet Vibration isn't really a problem. Instead they are more useful on a regular 15" sub that's running through my mixer. Also anyone who plays a drumset know's the impact of floor tom's. Well guess what, if you put these on floor tom's they help deaden the resonance (You need to be a drummer to understand what I'm talking about lol). So luv these things. 5 Stars. Thanks Amazon

The rubber was a little more firm than I expected so it seems these are designed for heavier subwoofers. Seems like the sweet spot is something at least 50 pounds but they still work on smaller and lighter subwoofers. They certainly protect the floor from scratches and stop annoying vibrations. They don't make nearly as much difference on carpet but still clean up the sound.I like that they are simple, look nice, and aren't permanently attached to anything. Overall they seem well made from quality materials so the price is fair.
