Silicone Speaker Isolation Feet (4-Pack, 1") – Non-Skid Adhesive Pads for Turntable, Subwoofer & Audio Gear – Anti-Vibration Damping, 20 Duro Rubber

Added four 1" hemispheres per stand to my API monitor stands to isolate the Elac UB5. Stands are already on spikes that are perched atop 2" thick Bamboo butcher blocks that also have 1.25" cones for isolation on a carpet over suspended floor. The stands had a slight resonance at certain frequencies still so I figured on decoupling the UB5 from the API top plates. The Platinum Silicon Hemispheres seemed like a good choice. Added the set of eight to the top plates and positioned the speakers back on top and sat down to do some samples that I had just listened to prior to the Hemi's. I consider myself an audiophile who is also a musician so I know when I hear a difference in my rig. The Elac UB5 are quite impressive at their price point and have been a alternate choice when I take a change of pace from either the Vandersteen's or the JSE Infinite Slopes here. As impressive as the UB5s are I was shocked at the "next level" sound that occurred by simply adding the HudsonHiFi Hemispheres. Mid-bass and bass both improved with less decay muddying up bass guitar, floor toms and bass drum. This also improved what was already a pretty decent performance from the concentric mid/tweeter driver Elac uses in the Uni-Fi series. Noticeable improvement in clarity over several octaves and instruments. After listening for hours I went and felt the stands for resonance in the columns, nothing there now. These HudsonHiFi Hemispheres are doing exactly what they were prescribed for, vibration isolation. Very impressive performance considering I've purchased some very expensive coupling and decoupling devices in the past that were magnitudes more money. This is for sure not the last purchase I make from this company. I look forward to testing their other products in my system.

In an effort to reduce some vibrations that are transferred to the LP player's cartridge, I bought a set of these Hudson Hi-Fi Silicone Hemisphere Bumper/Isolation Feet. These are easy to install, and have some excellent adhesion via 3M - just peel and stick. These feet could be used in a variety of situations on other components, but I wanted to try these on my Audio-Technica turntable.One thing I would say: measure first. They do offer several sizes and purchased the 1.25in set but I did not measure first. These are a little too small for my turntable but they are constructed very solidly. Also, my turntable feet 'float' a bit and swivel, so the small feet did not suit this setup as ideally as it could have. That was my fault. Being that the silicone feet are rounded, and a little too small, my turntable was moving around and not setting properly. I may try the larger size - better yet, if they were flat, it would work better in my situation.I believe these are engineered with the rounded ends such that there is minimal contact between it and the secondary surface. It is another well thought-out and high quality product from the designers at Hudson Hi-Fi. Be sure to measure the area that you want to modify and your results will be optimal.

Stable and improved sound/resonance on bookshelf speakers. Highly recommended

I like the elastic nature and shape of these pads. However I'm not happy with the adhesion side of things. Due to the nature of silicon ("oily" surface) the sticky tape comes off the actual pad very easily, whereas it will (continue to) stick like mad to the underside of my speakers. Hard to get off, actually. Sort of exactly the opposite of what you want. Also when installing the paper is hard to get off the sticky stuff and sometimes rather than just pulling off the paper you pull off the whole sticky tape. Nonetheless I have ordered, and kept ordering these over and over again as from a sound isolation perspective they are awesome for speakers, subs, amps and other audio equipment!

Great product, fast shipping. I have ordered this product a couple of times and the quality is consistent

Worked out great but actually used them for the bottom of my work cooler cause they don’t make rubber feet for it. If they ever need to be replaced I will definitely be buying another pack
