Preffair Audiophile Speaker Isolation Spikes Aluminum Record Player Shock Absorber Speaker Floor Protector Mat Adjustable Subwoofer Anti Vibration Pads Non-Slip LP Vinyl Record Player Base

Could not get a satisfactory tuning of my subs to the rest of my 5.1 system. I suspected sub was coupling to the floor. Isolation spikes did what they were supposed to do, now have great clean sub base. Before I had to reduce the sub volume by 9db. When I installed the Isolation Spikes, I had to increase the sub volume, which brought the entire surround system into balance. Absolutely wonderful. Now base frequencies are clear distinct and accurate and properly aligned with my main speakers. They are well made and worth there price. Note to negative reviewers: trying to mount them under the already installed feet will not work, I tried that, and will will make your devices unstable. It even moved tore the rubber pads from the isolation device. Remove the feet from your sub/turntable/speakers, and mount the isolators to the FLAT surface of those devices. Forces from my sub where such that it rotated the sub. Now with the isolators the sub stays in place. All in my first review are still valid.

Tighter bass that blends better into the main speakers. These feet eliminated virtually all the local vibrations and made songs feel more precise and... spacious even. Spacing the feet and balancing the subwoofer on them is definitely trial and error, moving the sub once set is a loathsome exercise. Overall a very effective and affordable alternative to the more expensive options out there. Would buy again.

Works great , stopped skipping with footsteps!

These are great for isolating your turntable from the cabinet, table or shelf on which it is stored. I was having some serious feedback when my turntable was placed directly on my credensa. I searched and found that using a butcher block and isolation feet are the remedy. I put these solid pointed style feet on the lowest tier closest to the credensa below the butcher block. Next tier, above the butcher block, between the turntable, I have spring style feet for added absorption. This combination allows me to play my music louder, with increased bass, and I have no feedback, no skating , just good tunes.

I purchased these isolation pucks for my turntable to reduce rumble induced by the placement of my speakers. Unfortunately they made no improvement at all for me. They seem well made, they have an adjustable cone inside the puck to allow the turntable to be level on all four corners. But I did return them because they did not make any audible difference.

I bought the black ones with the brass spikes and they were a great fix for my vibration issues. There was one place on the floor near my turntable that shook the hutch enough for the stylus to skip...installed these and no more issues. Was also convenient for doing some fine leveling. Both sides of these particular ones on this listing have rubber padding. I put some plexi down underneeth to protect my hutch's finish long term.

My new 4G Blu-ray player occasionally vibrate loud and annoying pitches with some movies!!!! tried lots of things to stop noise: rug underneath & foam sound stoppers around it Helped but not completely so I try these rotating feet now I don’t hear vibrating at all 😃

My turntable feet were not adjustable and these were an easy cheap fix to get it dead level. They are pretty small so I'm not sure id use them for large speaker isolation but worked great for my needs.

Not good for subwoofers mine fell off the feet. Stopped cheating out and bought isoacoustics which fit my sub.

I purchased 2 boxes of 4. I wanted to see if these were a cheaper alternative to Isopuck was worth it. I opened the box and each unit is made up of two parts, which are not connected together, you just let the top part sit on the bottom part. Keeping them horizontally level was very delicate. I could see no ability to isolate any vibration. I am returning them and going back to the good, but over-priced, Isopucks. If I am missing something, please let me know. They are so much more economical than Isopuck.
