Built by Hand. Driven by Sound.
From the Stage to the Workshop
Music has been part of Steve's life since before he could drive. By his early twenties, he was gigging nearly every weekend — clubs, stages, keyboards front and center. That lasted about five years, until a business to build and a family to raise pulled him in other directions.
The instruments never left the house. The love of music never did either.
The career that followed went deep into manufacturing — structural design, cosmetic design, mold-making, materials development. Years spent at the R&D level, figuring out how things are made and why they fail. That background doesn't leave you. It changes how you look at everything, including the speakers sitting in your listening room.
When Steve started casting concrete from 3D-printed molds on his workshop channel, it was curiosity driving the work — outdoor projects, experimenting with forms and mixes, seeing what the material could do. At some point, the question came up: what would a concrete speaker cabinet sound like?
Nobody had done it quite like this. That was reason enough to try.
What started as an experiment became the Arcus — a speaker that only exists because someone spent decades learning how things are made, never stopped loving music, and couldn't resist building something that hadn't been built before.
The Right Ears at the Right Time
Steve found Danny Richie the way most people do — a YouTube video that made it clear this was someone who didn't compromise on crossover design. He reached out cold. Got Danny on the phone.
The pitch was simple: he was building speaker cabinets out of concrete.
Danny's response: “You're doing what?”
He was intrigued immediately. Steve sent him footage of an earlier build. Danny was in. A cabinet with virtually zero resonance presented a different kind of design opportunity — a crossover optimized purely for the drivers, not compensating for a box that was coloring the sound.
Every component was selected for performance. Heavy-gauge air-core inductors from US Coils. Sonicap film capacitors. GR Research custom resistors. Pure copper wire throughout. Nothing chosen for convenience.
When Steve visited GR Research in person — production tooling freshly completed — Danny recommended switching to the Neo 3 planar magnetic tweeter. He described what it would do to the top end. Steve knew immediately it was right, and knew immediately it meant reworking the tooling he'd just finished.
He did it anyway.
That visit is why the Arcus sounds the way it does. Danny remains an ongoing collaborator — reachable, engaged, and still pushing the design forward.
Where Compromise Ends
Most of what defines a speaker's sound is never visible to the buyer. The cabinet material buried under veneer. The crossover components chosen by a spreadsheet, not an engineer. The internal wiring that nobody will ever see or question.
StoneSonic refuses to treat invisibility as permission to cut corners.
The cabinet is StoneCast™ — a mineral cast construction built using a proprietary molding process. The material's mass, density, and inherent damping properties dramatically reduce the resonance that colors the sound in wood-based cabinets.
Inside, every crossover uses heavy-gauge air-core inductors from US Coils, Sonicap film capacitors, GR Research custom resistors, and pure copper wire throughout. Every component was chosen because the music demanded it.
Every pair is built by hand in Steve's Utah workshop — cast, finished, assembled, and tested individually before it ships. There is no production line. There is no offshore facility. There is no version of the Arcus that exists because it was easier or cheaper to build that way.
