The Primacoustic Broadway Cumulus (Corner) Review explores how this tri-corner bass trap can revolutionise room acoustics with minimal visual impact. In this review, we dive deep into design, performance and installation to show you why the Broadway Cumulus sets a new standard in acoustic treatment.
Why the Broadway Cumulus Stands Out
Primacoustic has once again raised the bar with the Broadway Cumulus Tri-Corner Bass Trap. Engineered from high-density 6lb per cubic foot glass wool, it delivers broadband absorption down to 100Hz, effectively neutralising standing waves and low-mid resonance issues that plague many rooms.
Key Features
- High-density 6lb/ft³ (96 kg/m³) glass wool core for superior absorption
- Tri-corner design nestling in corners where bass accumulation peaks
- Resin-hardened edges with micromesh-bonded surfaces for fibre encapsulation
- Spring-tensioned clamping system for a secure, invisible installation
- 17" deep air cavity behind the panel optimising low-frequency control
- Class-A/1 fire-rated, wrapped in acoustically transparent fabric
- Available in three neutral colours to suit any décor
Design, Build and Installation
The Broadway Cumulus is as much a triumph of industrial design as it is an acoustic solution. Its reverse-bevelled edges and sleek fabric wrap blend into any environment. Installation is a breeze thanks to the proprietary spring-tensioned clamping system and the inclusive hardware kit—eye hooks, drywall anchors and spring clips—making setup almost instantaneous and completely unobtrusive.
Performance and Acoustic Benefits
Positioned high in the tri-corner, the Cumulus attacks bass buildup at its origin, delivering a marked improvement in low-frequency clarity and definition. You’ll notice:
- Reduced boom and chest-hump in voice-over booths
- Tighter bass response in home theatres
- Enhanced translation for mixing and mastering in professional studios
- More accurate acoustic measurement in post-production suites
This level of control opens up new creative possibilities—your mixes will stand up across any playback system, and dialogue will sit naturally without artificial EQ tricks.
Colour Options
The Broadway Cumulus is available in three architecturally neutral tones:
