I have a set of 8 IsoAccoustics reference GaIa I speaker isolation feet for sale. Purchased them new 3 months ago. This is an incredible tweet, that make a huge difference in the performance of your speakers. Major difference in the bass, more tight and deep response. Everything becomes more focused and much improved soundstage. As you can see, the original boxes included. They are in mint condition. Moving to another speaker, so I am need to sell them.
