The ZMF Atrium pairs biocellulose drivers with a patent-pending rear damping system for unmatched depth and openness. Rich, spacious, and immersive — a flagship open-back for those seeking natural tone and ultimate soundstage realism.

Openness redefined. Depth like never before.
Atrium [ey-tree-uhm] is a term from Roman architecture describing a central open space—often with a vaulted ceiling—that invites light and depth. ZMF Atrium brings that concept into audio: our most open design, using a patented damping system to enhance stage layering, depth, tactility, and natural timbre.
Atrium expands the spacious listening experience that began with the Auteur (now Auteur Classic). It uses the same biocellulose driver and ZMF’s linear tuning, while delivering even more space and immersion.
Like the Vérité, Atrium continues ZMF’s tradition of pairing innovative acoustic engineering with organic musicality. Its biocellulose driver delivers remarkable texture and microdynamics without giving up warmth or naturalness—hallmarks of the ZMF sound.
As the next step in ZMF’s open-back line, Atrium offers a sound that’s lush yet precise, with a wide, coherent stage and impressive depth layering. It’s built for deep listening sessions where technical performance and emotion meet.
The current stock wood for Atrium is Cherry, finished in a lightly amber natural stain, paired with a black grille and vintage-blue fabric—an elegant combination that also shines acoustically.
