Advanced Acoustics Bass Trap Corner Fill 12" x 12" x 12"


Introducing the Bass Trap Corner Fills – your solution for optimizing sound control in the often overlooked tri-corner of your room. Crafted to complement our 12" wide bass traps, these 12" cubes provide targeted bass treatment, resulting in a refined and balanced acoustic environment.

The Bass Trap Corner Fills are sold individually, each measuring 305mm (12") by 305mm (12") by 305mm (12"). Designed to seamlessly integrate with any of our 12" wide bass traps, these cubes elegantly address the tri-corner point, where two walls and the ceiling converge. This strategic treatment significantly enhances your room's frequency response and ensures a tidier finish when connecting bass traps to the ceiling corner. Transforming an otherwise underutilized space, these corner fills deliver additional absorption benefits. Available in both Mid Grey and Dark Grey, they effortlessly merge with your room's aesthetics.

Experience the Benefits:

Smart and Effective Design: The Bass Trap Corner Fills showcase a straightforward yet highly effective design. These corner-specific cubes fulfil a crucial role in any studio setup, prioritizing effective low-frequency control for an optimal acoustic profile. Bass traps stand as a cornerstone of studio design, and the Bass Trap Corner Fills provide a smart solution to combat the build up of corner-based low-end energy.

Combine them with our comprehensive range of acoustic tiles to address the entire frequency spectrum.

Neat and Professional Finish: The Bass Trap Corner Fills are tailored to fit seamlessly into the tri-corner, offering a tidy solution that eliminates the need for complex angle cuts on bass traps. The result is a polished appearance that enhances both sound control and room aesthetics.
