The ATOM 525 is a compact three-way standmount loudspeaker developed to deliver exceptional musical accuracy and natural scale from an elegantly proportioned enclosure.

Every element of its design is engineered to minimise coloration and maximise acoustic clarity.

A dedicated three-way driver configuration allows each frequency band to be reproduced by a driver optimised for its range, delivering improved detail, dynamic expression and natural tonal balance.

NODE’s proprietary Helical Transmission Line bass system is integrated within the enclosure, carefully controlling low-frequency energy while extending bass response beyond what is normally expected from a standmount loudspeaker.

ATOM 525 introduces NODE’s patented MonoCell damping. Instead of traditional fibrous damping materials, a precision internal lattice structure forms an ultra-rigid monocoque enclosure that acts as continuous bracing, dramatically reducing cabinet resonance and unwanted colouration.

The loudspeaker is available in a selection of refined finishes, designed to complement modern living environments while maintaining NODE’s distinctive sculptural design language.

ATOM 525 can be paired with its purpose-designed plinth stand, engineered to provide optimal listening height, stability and mechanical isolation.
