Sound Addicted Isolation Pads for Soundbar - Anti Vibrations Foam Pads Feet (4Pack) 3.5'' x 2.5'' x 0.65'' Suitable for Most Soundbars - BarPads (Rectangle)

These made an immediate difference. They are good at preventing bass vibrations from the speaker from causing noise and physical shaking. It cleans up the sound and makes it more natural. Bass is tighter and more focused. I didn't have a problem with the speakers actually moving around, but before I used these the speakers would sometimes vibrate against the surface they were on, causing noise that was not in the original audio. The size and thickness and construction quality are very good. Looking at some reviews there seems to have been a bad batch at some point, if the reviews are to be believed. That no longer appears to be the case.

Performs as advertised

Before this purchase- I first bought the Sound Addicted ISO pads for 5" Monitors under our KEF XIO soundbar- it was a shockingly noticeable positive difference that really improved clarity, separation, and punch; as it cancels-out resonances in our oak cabinet that causes some pretty severe "audio smearing". The next step was adding these Sound Addicted soundbar ISO pads that I placed under our Panasonic DP-UB9000P1K 4K Ultra Blu Ray player. If you think you cannot benefit from these under your player, think again. Those same resonances can be picked up through the chassis, and impact your player's performance. And it certainly did with ours, for a very low cost that's well-worth the purchase price. We also added Sound Addicted VibeBoss P10 for our KEF KC92 subwoofer (hence, the trifecta comment in the title of this review) and that component I'll review in its own section; but believe me, I'm so glad we did this. Night a day difference in sound quality for a very modest cost outlay. Truly!

They do the job. Cheap foam and a harder top. Should be around $7, but works for my soundbar.

This eliminated vibration from my soundbar perfectly.

I’m an audio file and have these under my Sonos Arc

To be completely honest, I’m not sure these are very effective. It helps to a degree that my soundbar is off the media cabinet, but I don’t detect very much sound absorption nor do I hear a difference…

Years ago I reading an audio magazine that said putting silly puddy under bookshelf speakers improved the sound. I followed this advice and it worked. When I saw these advertised I purchased them and replaced the silly puddy with these pads. These pads work better than the puddy and make the speakers reach their full potential. They absorb any vibrations and you get the natural speaker sound. Put one pad under each corner of the book shelf speaker on the shelf...4 pads per speaker. In my opinion it is a 50 dollar improvement in sound. Keep in mind so many factors affect the sound from the speakers. The type speakers themselves. The room they are in. The source of the music or movies. Other audio components. But these pads absorb the vibrations and will improve the final result.

Very happy with this purchase- should have got them sooner as they do a great job of stopping the vibration the bass can cause...

These seem to work well. They fixed my sound bar rattling right away

Erfüllt sein Zweck.

My roku soundbar/speaker had many buzzing/vibrating issues when perched on the shelf underneath the tv. It was incredibly frustrating to hear a loud buzz sound coming from the tv when watching a movie. But putting these underneath it IMMEDIATELY helped. There was ZERO buzzing/vibration noises when watching a movie while using these. This is just from personal experience of course. This helped me out so much now I can watch movies in peace.
