UFO ABSORBERS

Over the years I’ve tried a number of products the majority of them expensive through out my system some worked very effectively others made little to no difference.
The ViaBlue UFO absorber feet placed first under my speakers replacing the factory feet made an immediate I would describe first notable difference was tightening up of the low and sub bass registers ,"…just beautiful and for the price these ViaBlue absorbers are a stupid good value .
