Two independent rubber cushions + two solid wood keels for ultimate vibration controlDual Rubber Cushions (Top & Bottom)
Two separate EPDM layers (lower and upper) isolate the keels from both the subfloor and the upper structure. This double decoupling eliminates structural-borne noise and reduces impact sound by up to 25dB.
Dual Solid Wood Keels
Two independent kiln-dried hardwood keels (lower + upper) provide exceptional load distribution. The lower keel sits on the first rubber pad; the upper keel rests on the second pad, creating a highly resilient, floating substructure.
