Megasonus POLY100 – Broadband acoustic panel with PET core

The Megasonus POLY100 is a broadband absorber built to cut reverberation and tighten sound in studios, home setups, and offices. Its 100% PET fibre core delivers high absorption across the spectrum without mineral wool or harmful materials, wrapped in durable Gabriel Hush fabric on a solid wood frame. A clean, safe way to treat a room, available at Soundium.

Key Features

• Broadband absorption: High coefficients that reach full absorption from 500 Hz up, taming reflections across voice and instruments.
• PET fibre core: Effective 100% polyester core with no mineral wool, formaldehyde, or adhesives.
• Solid wood frame: Rigid, furniture-grade build that holds its shape on a wall or stand.
• Gabriel Hush fabric: Durable acoustic textile rated BS 476 Part 7 Class 1 for surface spread of flame.
• Integrated mounting system: Frame is prepped for quick fitting with the matching Poly mount kit.
• Safe for any room: No harmful substances, suitable for public and private spaces.

Customer Benefits

Place a few POLY100 panels at your first reflection points and the room stops fighting your mix. Flutter echo and boxy mids settle down, so vocals sit clearer and monitoring gets more honest. Because the core is PET fibre rather than mineral wool, there are no loose fibres or formaldehyde to worry about, which makes it easy to live with in a home studio, office, or shared space. The Gabriel Hush fabric keeps it looking sharp while it works.
