Eau Rouge CFRP Power Box 6-Port ER-PBOX

Unparalleled quietness and energy created by high-elasticity CFRP × pure copper × meticulously crafted structure

The ER-PBOX is a power box developed to bring the "overwhelming sense of energy," "richness of sound," "unwavering quietness," and "vast range" that were previously only achievable with Eau Rouge’s high-end models to a more accessible price range.
The chassis of this unit uses a premium grade of high-elasticity carbon fiber, far superior to standard CFRP, and adopts a hybrid structure that optimally combines multiple types of carbon fiber. By fully exploiting the material's potential, it achieves an unmatched level of rigidity and vibration control.

"CFRP for acoustics" structure optimized layer by layer

Although CFRP is inherently an excellent vibration damping material, Eau Rouge’s unique technology goes beyond that. Different types of carbon fibers are used for each surface, with layering direction, resin amount, and thickness finely tuned between 3mm and 8mm. This thoroughly suppresses internal resonance peaks, resulting in an extremely quiet chassis that almost completely eliminates the typical "box sound" of a power box.
The material itself increases sound density, delivers energy seamlessly, and absorbs unnecessary vibrations, creating a sense of silence as if the background has vanished.

Uncompromising power line with pure copper screws × American Electrical 7110GD

Special custom "pure copper solid screws" are used to secure the bottom, providing excellent acoustic and electrical properties. Their combination of conductivity and gentle resonance creates a natural soundstage with both delicacy and power.
outletThe unit also features the American Electrical 7110GD, well-regarded even in professional settings. Its secure hold and low-impedance contacts significantly contribute to stable current supply and the instantaneous impact of sound.
