Barbican: 6ixagon Acoustic Lighting Fixture

August 5, 2025

6ixagon: Adds Dynamic Elements of Silence, Aesthetic Warmth, Texture & Geometric Presence to Any Space

The 6ixagon fixture delivers a next level geometric presence with all the benefits acoustic fixtures bring and offers a choice of second colour of acoustic felt to allow for additional stylish options.

6ixagon helps to add some silence as well as aesthetic warmth, texture, and geometric presence to a space combining the best elements of architectural and decorative lighting into a single luminaire. The open top form factor creates an acoustic cavity in the center of the fixture to maximize echo and sound absorption.
