Product Range Overview

All panels are manufactured to order in our workshop with the utmost care and attention to detail.
Each unit is assembled by hand using a solid wood frame and PN70 Rockwool (density 70 kg/m³), selected for its optimal absorption characteristics and offered in five standard acoustic fabrics: Natural Burlap, Black, Dark Blue, Wine Red, and Rat Grey.

The range is divided into three lines based on width, but performance is strictly defined by thickness:

  • 50 (5 cm): Single slab. General mid-to-high frequency absorption.

  • 100 (10 cm): Double slab. Enhanced absorption for larger spaces.

  • 150 (15 cm): Triple slab. Engineered for low-frequency control and bass trapping.

  • 200 (20 cm): Quadruple slab. Ultimate low-frequency absorption. Designed for critical listening environments, sub-bass trapping, and eliminating room modes below 100 Hz.


    Absorption is determined by depth, not surface area. Think of sound waves as physical objects moving through the air:

  • High Frequencies (Treble): Small, fast waves. They are caught easily by the first few centimetres of material.

  • Low Frequencies (Bass): Massive, long waves. They require depth to be absorbed. A bass wave must travel deep into the material, rubbing against the fibres to lose its energy (converting sound into heat).

    Whether a panel is 78, 63 or 33 cm wide, the depth the sound wave travels into the material is identical if the thickness is the same.

  • Width determines how much wall space you cover.

  • Thickness determines how low in frequency you can absorb.


    — Technical Insight → The Power of the Air Gap —
    Why does leaving a space behind the panel improve bass absorption? Imagine sound waves as ocean waves hitting a sea wall.

  • Flush Mounting: When the panel is glued directly to the wall, the "wave" hits the surface and bounces back almost immediately. It only interacts with the very front of the material. This works great for small, fast waves (high notes), but the big, slow waves (bass) pass right through or bounce off before they can be absorbed.

  • The Air Gap Trick: When you mount the panel 5–10 cm away from the wall, you create a "trampoline" effect. The sound wave passes through the fabric, travels through the wool, hits the air gap, and reflects back into the wool.

    • This effectively doubles the distance the sound wave travels through the absorbing material.

    • It creates a zone of maximum friction right at the air gap, where the sound wave slows down the most.

      Practical result: A 5 cm panel with an air gap acts like a 10 cm panel. A 20 cm panel with an air gap, becomes a powerhouse for sub-bass, reaching frequencies as low as 80 Hz (the deepest rumble of a kick drum, bass guitar, or synth).

      Simple Rule → If you need to control bass or make a room sound "tighter," always mount your panels with an air gap. For the new 200 mm models, this is essential to unlock their full sub-bass potential.
