TECH & DATA
Why PANEL Thickness Dictates Performance (Not Width)?
This is the most critical concept in acoustic treatment. Absorption is determined by depth, not surface area.
High Frequencies (Treble): Small, fast waves. They are easily caught and absorbed by the first few centimetres of porous material (like the 5cm panels).
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 the panel is 78, 63 or 33cm 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 with that performance.
Thickness determines how low in frequency you can absorb.
So in practice, a wider panel treats a larger area faster, but it doesn’t reach lower frequencies than a narrow panel of the same depth.

whY CHOOSE larger panels OVER smaller/cheaper models?
This question gets to the heart of practical acoustic design. If performance per square meter is identical for Mini (63x63 cm) or Tall Wide (186x78 cm) panels of the same thickness, why choose fewer larger models over multiple smaller panels? Beyond simple wall coverage speed and surface area, larger panels offer distinct acoustic and practical advantages that smaller panels cannot replicate, even if you use enough small ones to cover the same total area.
-
Sound waves, especially lower mid-frequencies, behave like water flowing around a rock.
Small Panels: A 63x63 cm panel has a high ratio of "edge" to "surface." Sound waves can easily diffract (bend) around the small edges, bypassing the absorption material entirely. This reduces the effective absorption area, particularly for frequencies near the panel's cutoff point.
Large Panels: A 186x78 cm panel has a much larger central "core" area where the sound wave hits the material directly without being influenced by the edges. This ensures the theoretical performance (the NRC and frequency numbers) is actually achieved in the real world. Large panels act as a more solid "barrier" to sound energy.
-
Low-frequency sound waves are long (a 100 Hz wave is over 3 meters long).
Small Panels: To a long bass wave, a small 60 cm panel looks like a tiny speck. The wave largely ignores it, passing around it with minimal interaction. You would need a dense grid of small panels to trick the bass wave into interacting with the treatment.
Large Panels: A tall, wide panel presents a significant physical obstacle to long waves. It intercepts a larger portion of the wavefront, forcing more energy into the material. This makes large panels disproportionately more effective for low-mid frequencies (100–250 Hz) than an equivalent area of small scattered panels.
-
Mounting Points: Covering 4 m² with Mini panels might require 10+ individual mounting points, precise spacing calculations, and hours of labor to ensure they look intentional. Covering the same area with our Tall Wide panels might require only 3 or 4 units, drastically reducing installation time and potential failure points.
Visual Coherence: In professional studios or modern offices, a "grid" of many small squares can look cluttered or dated. Large panels offer a sleek, minimalist aesthetic that integrates better with architecture. They allow for creative arrangements (e.g., a single vertical column of tall panels) that small squares cannot achieve.
-
Gaps Matter: When you install multiple small panels, you inevitably have gaps between them. While some diffusion is good, large gaps can allow sound to reflect off the untreated wall between panels, creating a "comb filtering" effect (a hollow, metallic sound).
Seamless Treatment: Larger panels minimize these gaps. When placed edge-to-edge, they create a near-continuous absorptive surface, which is critical for control rooms or recording booths where you want to eliminate all wall reflections, not just reduce them.
Physical depth constraint is the priority; performance is maintained via thickness.
If the goal is critical listening (mixing, mastering, high-end home theatre), thicker medium-to-large panels are superior because they manage low-mid frequencies more effectively and reduce edge diffraction.
If the goal is general noise reduction (classroom speech intelligibility, making a busy office quieter, reducing echo in a gym), thinner small-to-medium size panels are often sufficient and more cost-effective.
Thickness matters most here, but larger widths (Wide-Line) cover more of the corner triad effectively.
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. When the panel is mounted flush 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.
-
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, crosses the air gap, hits the wall and then 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.
A 5 cm panel with an air gap acts like a 10 cm panel. A 15 cm panel with an air gap becomes a powerhouse for deep bass, reaching frequencies as low as 125 Hz (the rumble of a kick drum or bass guitar).
Simple Rule: If you need to control bass or make a room sound "tighter," always mount your panels with an air gap.

Frequently Asked Questions
-
The three lines exist to solve architectural constraints, not acoustic ones.
Wide-Line: Best for large studios or halls where you need to cover big walls quickly with fewer mounting points.
Standard-Line: The perfect balance for most home theaters, offices, and classrooms.
Thin-Line: Designed for narrow walls, hallways, or residential spaces where a wide panel would stick out too far or look out of place.
The Science: A 10 cm thick panel absorbs the exact same frequencies whether it is 78 or 33 cm wide. The difference is purely aesthetic and logistical.
-
Thickness is king. While the width and height of a panel determine how much wall space you cover, the thickness (5 cm, 10 cm, 15 cm, or 20 cm) determines which frequencies the panel can absorb.
Thin panels (5 cm) are great for reducing echo and clarifying speech (high frequencies).
Intermediate thickness panels (10 cm) offer balanced results around the mid frequency range.
Thick panels (15–20 cm) are required to absorb bass and low-mid frequencies.
Expert Note: A narrow 20cm thick panel will absorb deeper bass than a wide 5cm thick panel.
Always choose thickness based on your acoustic problems, and panel size (height & width) based on your available wall space. -
For large spaces where the goal is reducing general noise levels and speech intelligibility (rather than critical bass trapping), you prioritize coverage.
Recommendation: Our Wide-Line (5 cm or 10 cm) is ideal here. The larger surface area allows you to treat significant wall space with fewer units, reducing installation time and cost.
Mounting: In these environments, flush mounting is often sufficient since bass control is less critical than in a music studio. The 10 cm thickness offers a great balance of performance and profile for these spaces.
-
You need depth. Standard thin foam or 5 cm panels are excellent for clarifying speech and reducing high-frequency echo (like in an office or classroom) but they will do almost nothing for bass.
Recommendation: Choose our 150 mm (15 cm) or 200 mm (20 cm) models.
Placement: Install them in room corners (where bass builds up) or on the walls behind your speakers/subwoofer.
Pro Tip: Mount them with an air gap for maximum low-frequency control. The 20cm model is specifically engineered for "sub-bass trapping" application.
-
Acoustic foam is porous and lightweight, making it effective only for very high frequencies (hiss and snap). It is transparent to bass.
Our Choice: We use PN70 Rockwool, a dense mineral wool. Density is critical for creating the friction needed to stop low-frequency sound waves.
Durability: Unlike foam, which can degrade and turn to dust over time, Rockwool maintains its performance indefinitely.
Safety: Our panels are wrapped in breathable, acoustically transparent fabric that contains the fibers completely, making them safe for homes and studios.
-
The 200mm (20 cm) model is our "ultimate" solution for critical listening environments.
Performance: While the 150mm model absorbs down to ~125 Hz (with an air gap), the 200mm model pushes this boundary down to ~80 Hz.
Application: This extra 5 cm makes a massive difference for sub-bass (the rumble of kick drums, bass guitars, and synths). If you are building a mastering suite, a high-end home theater, or struggling with room modes below 100 Hz, the 200 mm model is the definitive fix.
-
NRC (Noise Reduction Coefficient) is the industry standard rating for how much sound a material absorbs, rated from 0.00 (reflects everything) to 1.00 (absorbs everything).
5 cm panels: NRC ~0.45 (Good for speech clarity).
10 cm panels: NRC ~0.80 (Excellent all-rounders).
15 cm & 20 cm panels: NRC 0.95 – 1.00 (Near-perfect absorption, especially with an air gap).
Note: Our ratings are based on high-density PN70 Rockwool (70 kg/m³). Cheaper panels often use lower density wool, which significantly reduces performance, especially in the bass range.
-
Mounting a panel with an air gap (leaving 5–10 cm of empty space between the panel and the wall) is the single most effective way to boost bass absorption without buying thicker panels.
How it works: The gap allows the sound wave to pass through the panel, hit the wall, and reflect back through the panel. This effectively doubles the distance the sound travels through the absorbing material.
The Result: A 5 cm panel with an air gap performs like a 10 cm flush-mounted panel. For our 200mm thick models, an air gap unlocks sub-bass absorption down to 80 Hz, making them powerful bass traps.
Simple Rule: If you want your mixes to sound tighter and your bass clearer, always mount with an air gap.
-
It depends on your goal:
Echo Reduction (Offices/Classrooms): Cover 15–20% of the wall surface with 5 cm or 10 cm panels.
Critical Listening (Studios/Home Theater): You need a mix. Start with 10 cm or 15 cm panels on reflection points (side walls, ceiling), and add 20 cm panels in corners for bass trapping. Aim to treat about 30–40% of the surface area.
