This auction is for a set of 3 Baby Promethean mini isolators, suitable for isolating a component weighing up to 30 lb. The Baby Promethean is a small hardened steel compression spring, diameter 1 inch, uncompressed height 1.5 inches, compressed height 1 inch. For lighter components weighing 5-20 pounds like CD players the target load of 30 lb for 3 springs can be obtained by preloading the springs with a granite slab, marble slab or by stacking marble or ceramic 12X12 tiles from Home Depot. See photo.
Resonant frequency of the mini isolator system circa 2-4 Hz, depending on direction. Due to their low profile, thus very good lateral stability, Baby Prometheans can properly isolate heavy components and even loads with high center of gravity. For components weighing 20-30 lb three Baby Prometheans can be placed directly under the component. For heavy components additional springs required, one spring for each 10 lb.
Price of Baby Prometheans $13 each or $39 for set of three.
