Basstrap Pro 2'x4' – Modular Acoustic Bass Trap with Air Gap
Low-end absorption, high-end design.
Built to Ground the Sound
The Basstrap Series is your low-frequency foundation — a modular set of absorbers designed to eliminate bass boom while matching the dimensions and design logic of every Massform panel. Available in 2'x2', 2'x3', and 2'x4', these absorbers integrate into your layout like silent anchors.
Engineered for Low-End Clarity
Each unit is built from high-density acoustic felt and features an integrated air gap, maximizing bass absorption while keeping a slim profile. Whether installed in corners or flush on walls, Basstraps tame sub-buildup while preserving the natural feel of your space.
Modular by Design
Every size in the Basstrap family aligns perfectly with Massform panels — visually, structurally, and spatially. From rhythm-driven walls to sculptural centerpieces, you can stack, frame, or flank your core layout with clean, intentional bass control.

Tune the Depth. Stack the Control.
Our bass traps are modular by design. Start with one. Add more. Each layer increases control over your room’s low-end — reducing boom, clearing out resonance, and bringing balance back.
Whether you’re building a focused mix space or a warmer listening zone, you can scale the treatment until your space feels right.
Built-In Air-Gap. Bass, Balanced.
A factory-set 1.3" (35 mm) cavity behind every panel smooths bass below 250 Hz, giving you controlled low-end the moment it’s on the wall — zero add-ons, zero extra steps.
Smart Assembly Meets Stunning Performance
Engineered for Effortless Setup
Each Massform Bass Trap is built with modular precision—connect panels seamlessly, mount securely, and transform your space with ease. No special tools needed.
