With Atrium, it's all possible. Atrium Closed follows closely in another advertisement of what the Atrium Damping System (ADS) can do for ZMF Headphones.
Following on a year after the titular Atrium which opened up new possibilities for ZMF, Atrium Closed is a worthy sequel. This closed-back flagship promises isolation and arguably Head-Fi's biggest sub-bass response, yet still exhibits the huge soundstage that defines its open counterpart.
This soundstage was a result of ADS granting ZMF tuning potential of Atrium Closed, in particular diffuse field control, through segmented airflow. Headfonics hails it as the complete headphone with "power and body on the low end ... for a closed-back it sounds spacious". It landed on Headfonia's Recommended Buys list.
Zach Mehrbach diffuses the airflow on each side of Atrium Closed's 50mm biocellulose driver. With separate cavities around a diffuser within this ZMF's cup, an exciting, vast and unforgettable sound is achieved – all behind the isolation of closed earcups. [See Product Desc. For More]
