NOT a gimmick! A real sound enhancer!
Crutchfield Customer Review (What's this?)
I had read several articles praising speaker foot accessories than were designed to largely de-couple the speakers from the surface they rest on. It made sense to me that a well-designed foot might let the speaker operate to it's full ability. I'd heard and read about Stillpoints, but the cost was high and they looked a bit gimmicky. When I ran across the Isoacoustics brand, the were somewhat more affordable and seemed like they might deliver what they promise. I ordered the Gaia II for my ProAc Response 1.5's. (I could have saved some money with the Gaia III, but I mis-remembered the weight carrying abilities of each.) What I found when installed was one of the best improvements in sound that I had ever experienced when optimizing my system. The sound was less "in-the-box" and more open and natural. The bass was tighter and more weighty. In fact, all frequencies seemed to benefit. There was more space around instruments and less blurring together. The Isoacoustics Gaia also made the speakers much more revealing. These feet are just a great, great way to take your sound to the next level. I'm VERY pleased.
Pros: Much improved sound
Cons: still a bit pricey - but then again, for audio, not too pricey takes some time to align properly if you also need to level your speakers
