Tertullus4 Pcs Aluminum Speaker Spike+Isolation Feet for Turntable Amplifier Subwoofer Black

We have a media space in the 2nd floor which has a carpet surface over a wooden floor. Subwoofer vibrations were absolutely terrible so found this and figured I’d give it a shot!After rerunning my Audyssey surround sound settings I was very surprised that these things reduced vibrations by 90% (anecdotal scoring) while not killing the output of the subwoofer.I’d absolutely buy these again! Totally worth it!

Seems to really help reduce low frequencies from my subwoofer traveling to the floor. Helps even more with a subwoofer dampening board that I have under them in the photo. The rubber feet are stickers and that is okay. They feel okay as far as the material quality.I have my sub under my desk and my feet right next to my sub and I do t feel ANY vibrations from my sub anymore unless I directly touch my foot rest to the side of my sub or the subwoofer dampening board.Probably would work best on tile or hardwood floors instead of carpet, which is why I'm using these in combo with the board.

These seem to be well made and are holding up well under the heavy weight of my large towers. I wish they didn't have the little labels on them but those are hard to see if you place them appropriately.I did notice an immediate difference in sound quality. Separating my heavy towers and subwoofers from the floor with these spikes definitely improved loss of sound due to vibration and excess floor vibration.They are not cheap and I have two complaints. One is that there is nothing to adhere them to the bottom of the speakers so if you have heavy speaker towers like I do, you have to be very tactical about placing these. Secondly, it takes quite a while to put all the non-slip pads on the backs of these if you get six sets of four spikes like I did!Otherwise, these are working great on carpet and I am guessing they would possibly work even better on hardwood or cement.

work though I am not sure that they help sound quality yet, and are over priced in my opinion.

Very nice looking speaker spikes, they are adjustable and very easy to use.The vibration on my computer desk has disappeared and the sound quality is much better with less distortion, speakers are more clean sounding

These worked better than I had even hoped they would. My sub sits on a wooden floor. After I installed these under the sub the rattling in the room was greatly reduced and the overall sound was noticeably cleaner.

This review is for Tertullus 4 Pcs Aluminum Spike + Isolation Feet - Silver. These are decently made, and they are height adjustable. It's also a benefit that a rubber pad is on the ends of both pieces. Their listing shows using this with the spike facing up, which is the opposite of what I have seen done for many years. I have never A/B caparisoned if the spike facing up or down makes any difference either. In theory, reducing vibration to a speaker or audio/video component can increase performance. I have not done enough direct comparisons to be able to give feedback one way other the other though. However, I will say one place where reducing as much vibration as possible is important is with record players. It is the component most susceptible to vibration for sound reproduction. Overall, these decently made isolation feet for the price point. I have seen better, and I have seen worse. I would call this a tier above entry level and a good value.

I have my Polk L100s sitting on sand filled Target stands (~45lbs each) and I've enjoyed the balance and imaging a lot. I bought the isolators on a whim and, man, I'm keeping these! Tightened everything up a noticeable amount, especially the imaging and soundstage width, height and depth. Worth every penny!

Sous ma table tournante, plus de retour de son, et on peut même claquer une porte et l'aiguille ne bronche pas du tout.

excellent

I bought this set and while I think the quality is good, trying to adjust them for use with a turntable is very difficult. If there was a better adjustment mechanism, these would be 5 stars for me.
