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.

Not it.
Size: 10, Color: Nude, Size: 10, Color: Nude
I ordered these and was highly disappointed. The first pair I got, the velcro pieces were coming off. The threading was either coming undone or just wasnt there. On both shoes. I sent them back, had them send me a new pair, hoping it was just a fluke, cause those do happen. The next pair was better, but the corners on the velcro pads were still coming up, and i just didnt trust it to stay together. I sent them back and got a refund. As for fit, the first pair fit great, my foot was a little to skinny I think, or the straps were too loose even pulled as tight as they could go while still being able to connect the velcro pieces. It was something I could have probably worked with, they looked cute still and I still wanted to love them. The second pair, however, straps were still too loose. That didnt change. However, I got the same size, but this pair, my toes were too long for. Like, they were up on the little toe ledge thats supposed to frame your foot. That was uncomfortable. So I feel like the sizing was inconsistent. Another reason I opted to send them back for a refund. The shoes are cute, and i usually dont have issues with this brand. I have a couple pairs of boots from them that I absolutely love. But these sandals were a huge disappointment, unfortunately.

Comfy but run large!
Runs large IMO. I originally ordered a 7 and they were much too big and the straps were way too long. I ended up returning them and ordering a 6.5, and I love them. They are SO comfy and they go with just about everything. I will say the top strap gets smudged easily, but I’ve just been wiping them with a wet cloth and the smudges are gone.

Great shoes
Size: 7.5, Color: Light Brown
Love these! Super comfy and love that they give me a little height. I'm a 7 to 7.5. had to go with the 7s. Don't recommend sizing up. The color is nice too. Definitely a great purchase.

So comfy, but aren’t well stitched.
Size: 9, Color: Light Brown
Really love the comfort of these shoes and all the straps are adjustable! However, the velcro on one strap came completely off a few weeks after purchase. I reattached it with glue, but it came off again. I plan to try to sew it back on because they are that comfortable. It is really frustrating though.
