Preffair HiFi Speaker Isolation Feet Spikes, Aluminum Shockproof Turntable Stand Feet, Speaker Floor Protector Mat, Adjustable Subwoofer Vibration Absorber, Non-Slip LP Vinyl Record Player Base Pad.

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.

Installé sous ma table tournante, ça a changé tellement l' isolation que je peux sauter dans le salon, claquer la porte et la musique continue sans soubresauts! Très esthétique aussi.

Although I had my doubts when purchasing,, the internals are all metal and the assembly as a whole is rock solid. The neoprene (or whatever the material is) on the top and bottom grip very well and stay putEasy to use, good price, and super fast shipping. All in all a very good, well designed product.While some may like it, if I’m being honest I’m really not a fan of the color scheme (blue with white logo printed on the sides) - but this is just a minor gripe as they truly do work very well.I will buy again.

These made a noticeable difference in the sound stage! Go for it.

These are well designed and precision made.
