Argosy Spire 420Xi Speaker Stands are made with Argosy's patented Iso-Acoustics technology and a 5/4" powder-coated substrate to provide a safe, sturdy, and resilient solution to isolate your studio monitors. Featuring beveled edges and a stunning look to enhance the feel of your studio. The isolators are designed to keep all movement on-axis - to move in the direction of the speakers cones' travel, while resisting movement in other directions. Place your monitors on the 420Xi and you will notice a definite tightening of the low end and improved stereo imaging of your existing speakers.
