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. (Sold in pair)

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 (96 kg/m³) glass wool, the Cumulus delivers exceptional sound absorption, is safe to handle, and has been tested to meet stringent Class-A/1 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″ (60cm) 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 theaters 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.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Not worth it!
Size: 6FT*6FT, Color: Black
These are the terrible. They keep falling down. The bottom part doesn't stay tight so it keeps turning making it in possible to stay standing. Its the absolute worst!
