Corner Kit — Mounting Hardware for Corner Bass Traps and Acoustic Panels

$805.00 TWD

Corner is where the low end actually builds up.

Move any panel into the corner.

Your panel already ships with flat-wall brackets. Swap them for these and the same panel straddles a corner instead

Two brackets in 2.5 mm thick 304 stainless, one on each wall. The panel hangs on an M5 screw with an adjusting nut, so you set depth and level after the brackets are up. Useful, because no corner in a real room is exactly 90°.

A panel across the corner leaves a triangular cavity behind it. That cavity is what does the low-frequency work.

Rated to 40 kg per kit, a bass trap and a surface panel together, with room left over.

One Corner Kit mounts one corner. Four corners, four kits.

Fits every Massform panel with a metal frame, every size and series.

Included: 2 brackets, 2 M5 screws with adjusting nuts. Snapskru dry wall screws.

You supply:

— 40 kg is the hardware. Both brackets need solid backing; in most rooms the wall is the limit, not the steel.
— Ships from our Taiwan studio, separately from your panels, around 2 weeks.

Recycled Polyester Felt + Brushed Anodize Aluminum Frame

Eco-Friendly

Our PET Felt Acoustic Panels are made of recycled plastic bottles, and therefore small variations in colour blends can appear.

How We Measured This Performance

We tested our panels in a real room — not a simulation. Using REW software, a calibrated mic, and our own space, we measured real acoustic improvements. Then we calibrated our results using certified lab data from our Surge panel.

If you're curious about how we did it, or want to see the full setup (yes, there’s a GIF), check out the full test:

We did the math so you don’t have to.

Turns out, looking good and sounding good aren’t mutually exclusive.

Fantastic little totebag with a touch of creativity

Some bags look good only when putting down, but the Rothko Tote surely looks great on my back! Not only was it versatile for everyday commute, it is sleek, stealth and stylish, well-suited for most attires dressing up or down. The tote is PACKED with compartments and I like how everything can just sits nicely in their own designated place without dangling. The only thing I would add is a little pen pouch but I guess given the circumstances it might seem obsolete. The bag is not expandable and has a relatively slim silhouette so don't expect to put on a truckload, but if you're looking for a nimble EDC bag paired with a artistic flair, I would 10/10 recommend the Rothko Tote.

Form and Function meet for beautiful panels

Not only are these panels beautiful works of art, their function as absorber/diffuser is top notch. Using in my audio room, the sound is much better with the Massform panels, than my previous panels.

Love them

These are perfect if you’re looking for acoustic panel to bring down sound reverberation and also look cool. I love the quality of these panels. The metal frame makes it very classy and unique. I haven’t installed them on the wall of my game room yet but I can feel the difference already. Packaging was also very professional; drywall anchors and screws were included in the box.

Well Designed and Wife Approved

Anesthetically, the panels are well designed. My wife loves them, although she wasn't much help in choosing the design. The 3 panel application really fits our living living room layout.I hope they provide dimensions that better accommodate a complete wall application down the line

Nice metal frame, beautiful and functional acoustic panels that double as art.

These are awesome panels! With the solid well-built metal frame, they do have a slight weight to them but more of a solid feel than bulky. The panels were all symmetrical and look even lined up on the wall. As far as performance, they do a great job and have comparable results to a 2'x4' owens corning trap. I lined these up along a window frame to cover up the window and to quiet some of the traffic noise and there is actually a significant difference with them installed. Of course the room is already treated, but these not only became the centerpiece, they also helped focus the sweet spot in the room where the vocalist stands. They have become a conversation piece as well. Some people ask if it's just art and I explain to them that it is designed after famous architecture and show them the pictures in comparison. It really does change the point of view and how you look at them. I really do love that they are functional art. It's up to you if you find the price worth it, but I do love how they tie the room together, make for an interesting look, and really help lower the noise floor in the room. I have built regular panels for significantly less, but they weren't as creative, didn't have a metal frame, and definitely weren't expertly cut into a piece of art! The only reason I took off one star was one of the panels actually had pieces of the design loose and floating around in the box. It had become unglued. For the price, I was expecting a panel that would stay together a little better. Nonetheless, I'm very happy with them and a little hot glue fixed it right up as it was obvious where the pieces went.
