GRAND PRIX AUDIO Apex Isolation feet Regular

Apex footers might look like classic ‘isolation’ cones, but they are far more sophisticated and effective than that.
They combine a hardened steel (or silicon-nitride ceramic) ball interface with a dual-purpose isolation/dissipation support. The external, structural elements are pressure formed from carbon composites, the void within the cone filled with a specially developed, proprietary polymer that decouples the upper element from the base. Originally developed for aerospace applications, this polymer exhibits extraordinary energy dissipation properties. The precision moulded cup offers a perfect contact surface for the ball, ensuring optimum energy transfer into the carbon cone and then, via the cone’s large internal surface area, into the polymer. The end result is remarkable management of spurious energy, whether that energy originates within the supported component, or is transmitted by the structure that supports it.
​
Adjustability
Unlike conventional cones, the APEX and the APEX XL also offer a leveling facility when used in place of spikes or threaded feet. Stainless steel levelers are tipped with a precision-machined cup that interfaces perfectly with the upper face of the APEX ball, providing
a rigid, stable and adjustable support. APEX Levelers are available in six different thread sizes (imperial and metric) incorporate thru holes for adjustment under load and are supplied complete with lock nuts.
