IMPOLUX GmbH

IMPOLUX GmbH from Kastellaun in the Hunsrück produces LED lighting and acoustic elements in its own manufactory. Under the SoundCover brand it makes absorbers from 100% PET fibre fleece with 50% recycled content: full-format boards, wall pictures, room dividers, edge and bass absorbers, and pendant luminaires whose body is itself sound-absorbing. Combining light and room acoustics from a single source allows project-specific custom builds. Shape, colour from 40 shades, design motif and lighting are configured per project.

IMPOLUX SoundCover VERTEX

Name: IMPOLUX SoundCover VERTEX
Brand: IMPOLUX GmbH

Description

SoundCover VERTEX is an edge absorber for rooms with demanding acoustic requirements. It reduces low and low-mid frequency reverberation as well as room-induced booming (modes) and was developed together with a room acoustician. The modules are fitted into the room edge on a modular slot-in system and also conceal cables or pipes. The A_obj value alone does not fully describe the module's effect: in room corners the edge effect adds to it, and that effect cannot be modelled numerically in common room-acoustics simulations.
