Manufacturer's Description from Primacoustic

  • Tri-corner trap is effective from 100Hz and up
  • Captures sound as it migrates in corners
  • Unobtrusive design fits any décor
  • Class-A fire rated—safe to use anywhere
  • Quick, fast and easy to mount in minutes

The Cumulus is a high-performance tri-corner bass trap that is designed to seamlessly integrate into most rooms without interfering with the natural room décor.

Given the choice, acousticians will always employ corners for acoustic sound control. This is primarily due to the way sound propagates inside a room, whereby the walls and ceiling act as waveguides that drive sound to the corners where it gathers. The Cumulus nestles high, up into the tri-corner where the walls and ceiling intersect for maximum efficiency.

Made from high-density 6lb per-cubic-foot glass wool, the Cumulus delivers exceptional sound absorption, is safe to handle, and has been tested to meet stringent class-A fire requirements for use anywhere. Front and back surfaces are bonded to micromesh and the edges are resin hardened to fully encapsulate the minute fibers. The panel is then wrapped in an acoustically transparent fabric to ensure maximum sound absorption. A unique spring tensioned clamping system securely holds the panel in place while making installation quick, easy and invisible.

At first view, the Cumulus appears to be quite large. But once the 24" panel snaps into position, it only extends down 17" talking up very little wall space. This creates a 17" deep air cavity behind the front facing panel that delivers broadband absorption down to 100Hz for control over model distortion in the problematic low-mid region. This makes the Cumulus the perfect acoustic starting point for home theatres and post production suites that have limited wall space and suffer from over-saturation of lower mid-range frequencies (boomy). For professional studios, the Cumulus helps eliminate standing waves and for voice-over booths, it provides an effective solution for the usual "chest-hump" that plagues most vocal booths in the 200Hz to 300Hz region.

The Cumulus tri-corner trap is a highly effective broadband absorber that comes in a choice of three architecturally neutral colors to match most room décors. The Cumulus comes complete with all of the installation hardware, saving valuable time

The Cumulus comes in 3 fabric colors: Black, Beige and Grey

About Manufacturer

If you are listening to the sound system in a church, PA system at an airport, or a concert in a hockey arena and are not impressed, it is probably not the fault of the PA system, but more likely the lack of proper acoustical treatment in the room.

Architects have just begun to understand that a great looking room that may be ‘functional for people’, may in fact introduce horrendous results when it comes to acoustics. This can be partially attributed to the lack of inter-disciplinary cross-training at universities and from a historical perspective, the science of acoustics has been kept a ‘dark secret’ that could only be conjured by mythical creatures called acousticians.

But this is changing. Through trial and error, advanced computer modeling and greater understanding of acoustical behavior, we can now predict with relative certainty how sound will behave in a given room. And as more and more folks have come in contact with acoustics, there is an appreciation for the benefits which, only a decade ago, were simply invisible. In fact awareness regarding the importance of acoustic sound control has gained such prominence that many top notch sound contractors will refuse to switch out the PA system in a church unless problems with the acoustics have been resolved for fear that the new PA will not yield any improvement and will only serve to tarnish their reputation.

Radial Engineering Ltd. pioneered the benefits of acoustics nearly 20 years ago by importing a brand of acoustic panels from Europe and supplying them to our customers. We quickly became frustrated as the product was expensive and it seemed that the company’s focus was heading towards industrial noise control—not music. We wanted a solution for studios, churches, broadcast and other music related venues. Primacoustic was created in Year-2000 as a means to provide simple solutions. Little did we know that within 10 years the market would completely shift, that most professional recording would move from the studio to the home and that schools and churches would begin to realize that the majority of their room problems were in fact caused by poor acoustics, not the audio system.

Today, Primacoustic has become a market leader in high performance acoustic products. Our ground-breaking Broadway acoustic panels not only grace the studio walls of international artists such as Tommy Lee, Nathan East, Scott Henderson, and David Bottrill, they have also been selected at gaming giants Electronic Arts and Transformers and were used to control the acoustics at the Vancouver 2010 Winter Olympics by US giant NBC and Canada’s CTV in the International Broadcast Center.

Primacoustic begins with the premise of a no-compromise approach on acoustical performance. In fact, Broadway panels are as good, if not better, than the most expensive panels made today. The ‘win’ is achieved by following the ‘Model T Ford approach’ of mass producing a limited selection as a means of lowering costs.

Primacoustic offers a wide array of acoustic solutions that spans all market segments. This includes special T-bar ceiling tiles that help retain sound inside a boardroom, acoustic clouds for call centers and studios and bass traps & diffusers for high end control rooms. Each product is engineered to deliver maximum performance while presenting the very best value.
