Manufacturer's Description from Primacoustic

  • Suspends over the console or listening position
  • Attractive fabric wrapped glass wool panel
  • Easy to assemble suspension hardware
  • Eliminates floor to ceiling reflections

The Primacoustic Stratus is an acoustical device that suspends above the recording console to control early reflections, flutter echo and help eliminate standing waves that cause resonant peaks in the critical mix position. Once in place, you will immediately enjoy a more controlled and intimate acoustic environment, larger sweet spot and reduced ear fatigue.

Attractive and very affordable, the Stratus ships in kit-form and is easily put together in minutes using a simple screw driver. The kit includes a 2" thick, 24" x 48" acoustic panel made from high density 6lb per cubic foot glass wool and suspension hardware. The glass wool is encapsulated with micromesh and the edges are resin treated to retain the minute fibres. For an attractive appearance, the panel is covered in an acoustically transparent fabric.

The suspension hardware consists of two light-weight aluminum rails and "L" brackets that form a rigid frame around the panel. To hang the Stratus, simply attach the included suspension wire to the frame. Hardware and fasteners for sheet-rock ceilings are included in the kit. Typically, the Stratus would be suspended above the console and clustered in an array spanning the width of your console and listening.

The Stratus absorbs sound energy by converting it to heat. Sound energy traveling via air vibrations penetrates the panel causing the minute glass fibres to vibrate and generate heat. This thermo-dynamic energy transfer effectively absorbs directional sound energy and prevents it from reflecting into the mix position.

By itself, the 2" thick glass wool panel is 100% effective for frequencies between 400Hz and 20kHz (see the acoustic absorption chart). To help control a broader frequency spectrum, the Stratus may be angled to vary the air space between the Stratus and the ceiling. This allows the backing surface to also absorb reflections off the ceiling.

The Stratus 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.
