SVSSoundPath Subwoofer Isolation System, 4-Pack

Exactly what I needed in my bedroom with faux hardwood floors (laminate) that creak and sound like the downstairs ceiling is about to split open. The house was built in 1988 and I weigh 176 lbs. So, it's not me breaking the floors.I had a feeling getting a 12" Polk PSW12 paired with my surround sound setup upstairs in the master bedroom would probably rattle the ceiling for anyone chilling in the living room trying to watch TV (older and weaker sound system muahahaha).Figured I wouldn't mind the wife yelling at me or texting me to turn the volume down. Two or three times, no problem.Then, I'm trying to watch John Wick one night. Marilyn Manson did a killer job with the soundtrack to a bad*** movie. Well, with the heavy bass notes and drum beats dropping nearly the entire movie which I thought was awesome...I had to turn the subwoofer completely off and even adjust the individual channel volume of my Elac B6 rear surround speakers, DefTech ProMonitor 800s for the middle down-firing Dolby Atmos ambience (worth every minute of my research and every dime spent from my savings), DefTech 1000s for the top-front left and right surround speakers, as well as the Klipsch Reference RF-250C center channel beast.When she was finally satisfied with the level of reverb from upstairs, I found out later that the side-firing Polk PSW12 subwoofer was the primary annoyance. Can you imagine if Ihad gone with even a 10" down-firing subwoofer? She'd probably vandalize my speakers in my sleep!I love listening to music, movie soundtracks, and anything encoded with Dolby Atmos now that I have my setup...but I can't crank her up unless my better half is running errands, working, out of the house, etc.Thank goodness my 8-month-effort in 2016 building-out this Dolby Atmos 7.1.2 man-made hasn't gone to waste!I came across these sound / bass dampeners after I left reviews for the speaker system I ordered last year and read the reviews. Compared the ratings to the cheaper and more expensive brands, but had a hunch these would do the trick for my subwoofer driving my wife nuts. Worked like a charm. Enhanced the bass so I can hear the notes more clearly from within the bedroom, but it's about as loud downstairs as someone tip-toeing around on the laminate hardwood flooring. Noticeable, but her Polk PSW10 - 10" sub now annoys me more often than I annoyed her. Gonna have to get another set or two =-DApplications:Side-firing subwoofers, down-firing subwoofers, 12" or 10" in size - doesn't matter. Even loud floor-standing speakers will benefit from a set of these babies. I think I'll put some under my computer which rests on top of a laptop cooler and my Pioneer Elite receiver - adequate ventilation.Conclusion:Great invention - the material and design are quintessential to the top notch end result post-installation.A foam or synthetic rubber pad under the entire surface area of the sub would not have worked as well as these dampeners.Take my word for it. I installed DynoMat inside cars and trucks in my teens for the sound-enhancing, reverb and vibration reduction / elimination effect they provided people with upgraded sound systems who reported rattling sounds from their inner car door, dash, or trunk lid / pickup truck bed resembling silver bubble wrap style sunshades for cars

The feet do not attach as well as they need to be for casual moving and handling. The larger foot size creates more distance from the screw and thus creates more leverage to sideways pressure on the screw which can cause it to fail. They come with a warning about casual handling and moving the subwoofer because the feet become more vulnerable to being torn off the subwoofer or broken and so on. Other than that, this is a must buy for any serious home theater user.My 1400-watts peak performance BIC PL300 subwoofers really love these new rubber feet but the screw used to attach the stock rubber feet is very small in comparison to the ones here. I had to very carefully move them into place. I do not want anything to bump into them either as the very relatively small screws will literally be screwed is the wood breaks. This is because the larger the screw size the weaker the wood around the screw is. Thus, the wood around a larger screw would have wood that breaks or flakes easer which is only offset by the larger screw thread volume on the wood.All else makes the new rubber feet for the subwoofer a no brain winner. The sound is much better and clearer, especially with less rattling and rumbling as the house shakes with the music. It is quieter outside and much louder and clearer inside while running more efficiently under less stress. When the subs run smoother, the less they fatigue less and push loud and clearer with less effort. Win win win win.Go buy these now but be careful installing the rubber feet and handling them afterwards or they will brake off too easily to work to the oem standards of durability you would expect for a commercially made product.My 5,000 watts of home theater never sounded this good before and my neighbors have to be loving it too. They say that I live in the house of a thousand drums.

Worth every centReplaced the feet on a klipsch spl-100 with these as well as a svs pb3000. For the klipsch, they are paired with a set of "the fives" and connected to a record player. I was getting a lot of resonation through the record player. After trouble shooting, i figured out that i was getting resonation from speakers. Paired these with a set of "feet, rubber, for the fives and some noise isolation pads for record player and all resonation is gone.My spl-100 now sounds completely different than before, and I mean a lot different/better. Seems more punchy and less floor vibration.On my svs pb3000, I got ALOT!!! of resonation through the floor. These eliminated about 80-85% of it. Still get some, but that sub will shake the neighbors walls 100 feet away, so didnt expect to resolve all of it, but they doo a very very good job compared to factory ones. Now just have to get 1 more pair for a spl-120.

WOW these are really nice, great quality! Really helped to reduce in room vibrations with the two SVS-1000 Pro subs I have in the living room with my home theater setup, exceeded my expecations!

First off I never write reviews, but I hope this review will help those that are in the situation I was. I was hesitant to buy these because my home theater is in the basement with a carpeted concrete slab. Most of the reviews are from people with a wood sub floor and the few things I read about concrete that it wouldn't make much difference. Boy were those reviews wrong. I am running two 18" Dayton Ultimax 2's w/ 1000w RMS amps in custom enclosures, and the results from these isolators was immediate. I have so much less room resonance from 20-80hz. The bass is clear and more refined. It did pull some punch from the subs via less room gain, my subs have enough headroom to compensate for this. The isolators are well built and perfectly engineered to do what they advertise. What a great product. So if you have a powerful sub setup and are on concrete give these a try.
