New Six-Balanced Armature Architecture

Fathom is equipped with six custom-made balanced armature drivers, each designed with a specific role in mind to enhance your listening experience. The configuration includes dual custom high-definition super tweeters for crisp, clear highs; a pair of custom mid-range drivers for accurate vocal and instrument reproduction; and dual custom BA woofers for rich, balanced bass. This setup is meticulously engineered to deliver precise sound reproduction across the entire frequency range.

Tuned With Intention

This curve displays relative volume levels at each point across the frequency spectrum, reflecting Fathom's careful balance and refinement in tuning. Though FR curves are a great general guide, they can't convey technicalities like soundstage, imaging, layering, etc.

Elegant Design

Fathom is encased in a machined aluminum body anodized in a sleek, black, bright-dip.  The Rainbow PVD fasteners cast a vibrant spectrum of light against the deep black of the anodized shell, creating a striking contrast that is both visually captivating and elegantly understated.
