Subwoofer Isolation Pad - 4 Pcs 2 X 2 X 2 Inches Bass Reduction Floorstanding Speakers Mat Riser - Thick Large Rubber Cork Anti Vibration Pads for Heavy Machine Equipment Studio Monitor Stands

As others have said, these do have a fairly strong odor out of the packaging. These are a good size chunk of rubber and cork specs that are bonded and compressed. Compared to my existing ones that are thinner have a foam middle being sandwiched by rubber. Didn't noticed an immediate difference, but over a short period of time, I noticed an overall fuller sound from the subwoofer. Honestly, didn't expect much difference at all. Not sure if the increase in space under the sub was any factor or that these dampened vibrations from the floor better. Materials like rubber, foam, or cork have varying dampening or isolation factors due to their physical properties or even density. These are bonded specs of rubber and cork, so I'm wondering if there are any collision factors that helps to dissipate vibration similar to sand or any fill people use in speaker stands. I really don't know, but I'm happier with the TV audio and will test this on my audio system. I also placed silicon rubber under the soundbar's thin rubber feet with some improved clarity. Keeping expectations real, my soundbar+subwoofer are not HiFi, but will test on my 2 channel system for its' effectiveness.

This worked awesome with my modded and heavy ESS AMT3's-now weighing 130+ lbs. Located on a wood floor this cleaned up the bass perfectly. Expensive, but much less then audio specific units-and very effective-thanks!! FIY-I got the idea from a Stereophile review of Klipsch Forte III speakers, were the reviewer was experiencing similar muddy/boomy bass issues. I tried rubber pads/ felt pads, wood blocks etc. Nothing worked well till I tried these. A excellent product and great value, using proven, simple and effective materials and construction. Thanks guys for a great product!! P.S.-Unlike Stereophile_I used 4 per speaker. First to keep the speakers better balanced-plus my speakers are quite a bit heaver then the Klipsch Forte III's. So I would say may sure weight of your product you need to isolate, and balance is taken into consideration.

This will help dampen vibration for my blender. The material is still brittle so it sheds when handling.

Works well to dampen low frequency vibrations

I live in a solar powered off-grid cabin with a 2,650 gallon cistern for water, which is up-hill from the cabin but not high enough to provide reasonable pressure so I have a 24VDC water pressure pump inside the cabin to maintain an even 60PSI to all water fixtures. I tried mounting the pump directly to the wall but the wall acted as a sounding board that amplified the noise of the pump. Searching Amazon, I found this BXI Soundproof Tile - Anti-Vibration Pad - Isolator. I re-mounted the pump on the pad and much to my hopeful expectation, the pad isolates the vibration of the pump from the wall quite well. It is now much more quiet.

The glue that holds the cork and rubber bits together is not very good. Just holding the blocks caused pieces to fall off. The blocks arrived as different sizes and not fully cut through leaving little bits on the end. I had to cut off the remains with scissors. Thankfully, two blocks where the same size while the other two were also the same size. If they were odd sizes that would induce wobble in my 3D printer. Despite these product defects, they do their job. I would only use these indoors and away from moisture. If it weren't for these obvious production defects I would give these 5 stars.

Looked sturdy, but returned as I opted not to use them. They appeared to be well made

I am not aware how much, if any, glue is used in putting these together. What I hate is how easily they crumble. I did place them under a subwoofer and vibrations are significantly reduced. However, when vacuuming/mopping around them, every touch needs to be very light to avoid pieces falling off. By cleaning, I am wearing them out. How is this reasonable? Concept is good, but implementation is the issue. I could dip them in some glue to get a stronger shell, but what if in the long run the shell won't be able to hold them together? After all, they would be under vibration stress. They look so convincing in the pictures, but when you hold them in your hand, almost any time some you touch the edges small pieces would likely flake and fall off. To be a better product, they need more glue to hold them in one piece. At $20 a pair, these blocks need to have stronger bonding materials.

Good product. I tried many other products before. This is the only one that made a difference.

Solo compre un par para un sub de 8, hizo una diferencia más que notablemente, probablemente con un par más sea perfecto💯✨

I bought these to use between the floor and power conditioner for my audio system. I have 2 subwoofers which I thought were likely transferring vibrations to the power conditioner. I placed 2 of these pads under the conditioner and immediately noticed a change for the better. I actually ended up lowering the volume of each subwoofer by 2 notches. That's a relatively large change. I'm wondering where I can use the pads next. Very happy with the results.

Used these to isolate my center channel speaker. Compared to isolators worth hundreds of dollars, these things are possibly better. Not sure why people are leaving negative reviews to be honest. Id highly recommend them.

They certainly helped decouple my subwoofer from the floor and rattling other devices near it
