Pi™ BASS TRAP – Low Frequency Acoustic Absorber

Pi™ BASS TRAP is a precision-engineered acoustic solution created by DECIBEL to control and absorb low-frequency energy between 125 and 250 Hz, ensuring a balanced and accurate sound environment. Built for professional and residential use alike, it effectively reduces the low-end buildup that often distorts sound clarity and masks higher frequencies.

The panel’s distinctive design combines a wooden perforated faceplate with an acoustic foam core, delivering both structural integrity and advanced sound absorption. Suitable for installation in corners and junctions where bass frequencies concentrate, Pi™ BASS TRAP brings acoustic precision to studios, conference rooms, and home cinemas alike.

How It Works

The wooden faceplate features 15 cross-shaped perforations, covering precisely 3.14% of the surface area. This unique geometry surpasses traditional circular perforations by optimising airflow resistance and improving low-frequency absorption.

Behind the faceplate, the acoustic foam core acts as a resonator, capturing and dissipating low-frequency sound waves that would otherwise bounce back into the room. The combined system transforms unwanted resonance into low-grade heat energy, achieving cleaner, tighter bass response and enhanced intelligibility across the frequency spectrum.

Key Benefits

• Absorbs low-frequency energy (125–250 Hz) for balanced sound performance.
• Innovative cross-perforation design improves efficiency over standard perforated panels.
• Constructed with a 7 mm thick wooden faceplate for strength and durability.
• Lightweight and easy to install in room corners where low frequencies accumulate.
• Elegant design blends seamlessly into both professional and residential interiors.
• Provides improved mid and high-frequency audibility by removing low-end resonance.

Installation Overview

Pi™ BASS TRAP is designed for corner installation, where it neutralises the highest concentration of low-frequency sound pressure. Panels can be securely fixed using DECIBEL’s recommended polyurethane adhesive, ensuring precise alignment and long-lasting stability.

No specialist tools are required, and each panel’s lightweight structure makes handling simple, even in large-scale installations.
