The Strange Attractors are one of the premier isolation footers in the industry. Combining the benefits of graphite and aluminum in its composition, the Strange Attractors help “dissipate” any vibrations from permeating into the component or speaker it is attached to. The set you see here comes with 1/4-20 threaded studs. We have the original packaging for it. Except for minor scuff marks, the set looks really good.
