How To Use The Cumulus





Easy to install.

We often get asked why the Cumulus is so unique. The answer is not so much the concept of using the tri-corner as this has been well known for years. What makes it unique is the combination of the high-performance panel with our innovative spring mounting system. For an acoustic panel to be used, it must first be presentable. If all kinds of screws or hardware is visible, it simply will not make it into the living space!

 

The mounting system is made up of five (5) components:

  • Corner claws to grab onto the panel edges
  • Springs that keep the claws tensioned
  • A key-chain ring to attach the springs
  • An eye hook to hold the Cumulus up into the corner
  • A zip-tie to tension the device and hold it in place

 

All you do is attach the claws and springs to the Cumulus, mount the eye-hook into the ceiling and then snap the whole assembly together in place. Once up, it nestles nicely and almost invisibly into any room décor. If ever you want to move it, you simply pull the edge of the cumulus away from the wall, cut the zip-tie and it will release.

As for colors, the Cumulus is available in beige, grey or black. Should you wish to change the color, all you need to do is re-wrap the panel with any breathable cloth and spray adhesive. Only thick vinyl will have an effect on the sound as high frequencies may reflect off the harder shiny surface. Woven cottons or polyesters will simply be invisible.

Application 1 – Small room, lots of windows, limited wall space

We know that it takes a certain amount of acoustic absorption in a room before a difference can be heard. Often when dealing with small rooms in homes and offices, there are multiple large windows, artwork, whiteboards… any number of things that can leave one scratching their heads wondering where acoustic treatment can be installed. Traps are usually big and bulky but the Cumulus tucks neatly up into the corners of the room, leaving the architectural design of the room intact and providing broadband absorption where placement of traditional panels and traps is difficult or out of the question.

Application 2 – Voice-over booth, evens out low-mid bump in room response

The low-end of the vocal range is often problematic in voice-over booths. These low-mid frequencies are further amplified by less than ideal room dimensions, creating a boxy sounding recording. Typical of booths treated only with acoustic foam, this boxy sound is referred to as ‘chest hump’. Installing the amazingly compact Cumulus trap into the corners of any booth will yield significant absorption in the 100Hz to 250Hz region, effectively solving most low-mid frequency issues in the booth without sacrificing valuable real-estate with larger bass traps.

Application 3 – Home theater

Home theatres are often constructed in a main living space within the home, making for a room that is truly multi-purpose. Not only do doors and windows create a challenge when placing acoustic treatment, but artwork, bookshelves, surround systems, projectors, large screens, and aesthetic considerations make it extra difficult to place panels and traps. The seamless installation of the Cumulus into the upper corners assists with overall broadband absorption and bass trapping in the room, while remaining non-obtrusive and fitting easily around other barriers.

Application 4 – Odd mounting around door frame

Sound waves follow wall and ceiling planes and accumulate in corners, a well-known hot spot in any room. Corners can be easy to treat with a traditional bass trap, but quite often doorways and windows eliminate the possibility of hanging a bulky bass trap. The compact footprint of the Cumulus makes for easy installation around any obstacle, providing efficient corner trapping in the smallest of spaces.
