Primacoustic Cumulus Tri-Corner Bass Trap – Pack of 2 (Grey, White, Black, Beige)

The Primacoustic Cumulus is a high-performance tri-corner bass trap, engineered to deliver broadband low-frequency absorption right where it's needed most—in the corners of your room. This pack of 2 traps is ideal for treating home theatres, recording studios, mixing rooms, or vocal booths with boomy low-mid frequency issues. Designed for ceiling-wall corners, the Cumulus fits discreetly, combining top-tier acoustic performance with an architecturally neutral appearance.

Why Choose the Primacoustic Cumulus Bass Trap?

Corner-mounted for maximum low-frequency control, the Cumulus is an ideal solution for environments with limited wall space. Its 17" air cavity enhances absorption efficiency, especially in the 100Hz–300Hz range, commonly problematic in voice and music applications. Whether you're mixing, recording, or building a home theatre, the Cumulus provides powerful acoustic control with a clean, professional look.
