This ad is for a set of 4 of our new isolation device, Super Stiff Springs, for very heavy components such as subwoofers, heavy turntables such as Verdier, VPI, Raven AC, and very heavy amps. The set of 4 Super Stiff Springs is recommended for components weighing at least 100 lb. and weighing up to 200 lb. Because the Super Stiff Springs are only about 1.5 inch compressed they have very high lateral stability and can usually be used directly under the component. Super Stiff Springs like all of our springs now come cryogenically treated.
For lighter components weighing 20-45 lb. use our Baby Promethean mini Isolators. We also have springs for very light components in the range 5-10 lb. All Springs are small low profile steel compression springs and are cryogenically treated for superior performance.
