Surge Pro 2'x4' Acoustic Panel – Sandstone with Air Gap
Presence, not noise
Surge was shaped by the natural rhythm of moving air and drifting waves. It's designed to soften sound and bring calm to creative space. Its sculptural surface diffuses reflections. The hidden air gap extends absorption into deeper frequencies, but without taking over the room.
Engineered for balance.
Tested to ASTM standards. NRC 1.15 performance (in bass trap configuration).
No foam. No filler. Just quiet clarity, made visible.
“THEY’RE SO BEAUTIFUL, THEY INSPIRE ME TO CREATE.”

The Story Behind the Shape
What’s the story behind the Surge Series?
It came from watching the rhythm of sea washing beaches and rock sediment lines during a hike after a storm. The earth felt heavy, still wet from the rain, but the air was alive. That tension, between stillness and movement, is what Surge is built on. It doesn’t just represent a flow. It carries it.
Surge feels sharper and more directional than Wave. Why is that?
Surge has more vertical energy. The lines don’t just drift. They lean. There’s momentum in the form, almost like a frequency building up pressure before release. It was designed for people who want presence in their room, who want to feel lifted, engaged, not just calmed.
What inspired the visual aesthetic of Surge?
I was thinking of volcanic sediment flows, striated sandstone, and the shapes wind cuts into cliffs. Things that look like they were pushed by time. Surge echoes those forms, but in a way that feels designed rather than eroded. It has intent.
What do you want people to feel when they look at or touch Surge?
A sense of movement. Like something is shifting, inside the panel, inside the room, inside them. Surge isn’t loud, but it has momentum. It doesn’t calm you down. It wakes the space up.

PERFORMANCE
Our panels don’t just look great — they deliver real acoustic results. This chart reflects how sound behaves with our material in play.
- Surge Series w/ basstrap NRC 1.15
- Surge Series NRC 1.00
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:
Built-In Air-Gap. Bass, Balanced.
A factory-set 1.3" (35 mm) cavity behind every panel smooths bass below 250 Hz, giving you controlled low-end the moment it’s on the wall — zero add-ons, zero extra steps.
Modular Basstrap Compatible
This panel is ready for deeper bass control. Just snap on our modular basstrap kit whenever your space needs it — no replacements, no hassle.
We did the math so you don’t have to.
Turns out, looking good and sounding good aren’t mutually exclusive.
