What's inside
A custom high-density polyester core, heavier and more absorbent than typical panels, tuned for stronger low-end control.
IsoCavity TM Compatible Add-on
A modular air-gap option, sold separately, that creates space behind the panel to improve lower-frequency performance.
ModuBASS TM
A flexible bass trap system designed to scale up or down as your acoustic needs change.
What customers say
Dimensions

3 pieces of 37.5" x 21.5" x 2" THK (950mmx550mmx50mm)

Materials

Polyester (PET) Acoustic Felt + Brushed Anodized Aluminum Frame

Color and texture

Our felt is a blend of colored polyester fibers, so small variations in color and texture between panels and production batches are normal.

How it works

Lab-Tested Performance. Without the Lab Look

These sculptural panels pull double duty — aesthetic in the gallery, acoustic in the studio. Verified in the lab, felt in the room.

How much sound it absorbs

PERFORMANCE

Thresholds Acoustic Panel Set – Moon Shadow (3 Panels)

Our panels don’t just look great. They deliver real acoustic results, and this chart reflects how sound behaves with our material in play.

Select a configuration to compare absorption.

Values above α 1.00 are a normal result of reverberation-room testing: sound diffracts around the panel’s exposed edges, so the panel absorbs more energy than its face area alone accounts for.

Why the shape matters

Lab-Tested, Design-Driven

Our Art Series panels were independently tested under ASTM C423 standards at NTU in 2024. Even without an air gap, the flat-mounted panel achieved a strong NRC of 0.82, validating the acoustic performance of our material and surface geometry.

Built with architectural precision and expressive form, the Art Series blends design and function — diffusing reflections, reducing echo, and enhancing clarity across a wide range of spaces.

Works with Basstrap Pro

Modular Basstrap Compatible

This panel is ready for deeper bass control. Just snap on our modular basstrap kit whenever your space needs it — no replacements, no hassle.

Installation guide

Installation guide

Each panel hangs from the hook on its top rail: on the three screws and drywall anchors that come with the set, or from a picture rail. The guide shows both, step by step, in millimetres and inches.

Why a producer chose Massform

🎵 “Most of the studios I’ve built were acoustically incredible, but felt like a dungeon. I wanted something that sounds amazing and actually makes me want to create.”
Rowan Garmon, producer and musician

Add an air gap

Modular Air-Gap Compatible

This panel ships studio-ready. When you want even tighter lows, simply snap on our 1.3" (35 mm) Modular Air-Gap Kit to tame stubborn bass — no need to replace the panel you already love.

How it compares

How much sound Art Series absorbs, beside 25 mm acoustic foam and a 2-inch fibre-board panel.

  • Art Series, without Basstrap 0.80 lab-tested
  • Art Series, with Basstrap 1.00 estimated
  • Two common panels
  • Acoustic foam, 25 mm 0.50 maker’s lab test
  • Fibre-board acoustic panel, 50 mm 1.00 maker’s lab test
How we know
Lab-tested at National Taiwan University (NTU · ASTM C423-22) as a mixed set of 18 Art Series panels laid flat. With Basstrap: estimated, not tested.
The shape
The relief scatters sound in the mids, 500 Hz to 1 kHz.
The common panels
One common product of each type, from its maker’s published laboratory test, brand not named; not measured by Massform. Both laid flat with no air gap: the 25 mm wedge foam at Riverbank Acoustical Laboratories (ASTM C423, 1993), the 2-inch fabric-wrapped fibre panel, 56 mm as tested, at the University of Salford (ISO 354, 2014). That test states no NRC, so Massform worked it out from the report’s bands.

NRC: how much sound a surface absorbs, averaged across the range of the voice; higher absorbs more. Solid bars are lab-tested or measured, striped bars calculated or estimated.
