GRAND PRIX AUDIO Product Launch: New APEX XL Footer and APEX Mini Coupler — Room 2024, Summit Tower

For years, Grand Prix Audio’s APEX footers have set the benchmark when it comes to component support. Challengers have come and challengers have gone, but still the APEX sets the performance standard that others strive to match. As the industry and customers have started to realize the crucial musical implications of effective mechanical grounding and equipment support, interest and competition has increased, but the APEX still reigns supreme – until now.

Go Large…

The new APEX XL employs the same proven structure, materials and interface elements as the original APEX, but increasing the diameter and height of the cone more than doubles the internal volume of the proprietary polymer core, increasing its energy dissipation capabilities. The same hardened steel or ceramic interface ball is supported in a precision moulded cup that ensures rigid coupling and superior energy transfer, while the increase in internal surface area of the carbon composite structural cone further improves energy transfer. Supremely efficient when it comes to sinking internally generated vibrational energy, the decoupled baseplate is equally effective as a barrier against external mechanical interference. In this case, bigger is simply better. Perhaps the ultimate example of K.I.S.S-thinking the APEX XL is compatible with the same stainless-steel levelers as the APEX (available in six different thread sizes) making it an incredibly cost effective upgrade not just for Grand Prix Audio racks, but for the spikes used beneath all other racks or speakers, or as a straight swap for existing APEX footers, beneath racks, speakers or individual components. 

The APEX Mini

One practical issue with equipment couplers is that they increase the height of components – and sometimes that height just isn’t there. When space in your rack is tight but you still want APEX performance, or your equipment has small feet and you don’t want it looking like it’s perched on stilts, the APEX Mini is the answer. A scaled version of the APEX, it is 0.225”/5.7mm lower, which might not seem like much, but can make all the difference. A dedicated component coupler rather than for use beneath racks or speakers the APEX Mini is not compatible with the APEX levelers. It is however, the only way to achieve APEX performance in a more compact package.
