The Sinfonia Collection

Elevate your speakers with the Sinfonia Collection. Featuring enhanced diaphragms, refined paper treatment, and improved clarity across the spectrum.

Sinfonia COLLECTION

Refined Harmony in Every Note

Drawing from the visionary designs of Paul Voigt and O.P. Lowther, the Sinfonia elevates our full-range philosophy with a newly developed premium diaphragm. Enhanced cone structures, refined spiders, and a proprietary paper treatment process harmonise to deliver noticeable refinements in clarity, resolution, and tonal accuracy. Yet, the soul of Lowther remains unaltered: that timeless, authentic sound which reveals music's deepest truths.

These instruments integrate seamlessly into custom designs, providing a significant leap in performance - from crystal clear transient response to precise sound-stage imaging. Experience the warmth of natural materials, the precision of hand-wound voice coils, and the enduring legacy of Lowther.
