Where Compromise
Ends.
Handbuilt in the USA
Speakers with cabinets cast from solid mineral composite — an enclosure so dense and inert it adds nothing of its own. You hear the drivers, never the box.
“The best vocal I’ve ever heard out of that M165.”

“It took 10–15 seconds. Immediately this is magic.”

The Cabinet
StoneCast™. No Parallel Surfaces.
Mass & Rigidity
StoneCast™ delivers dramatically more mass and rigidity than MDF, eliminating cabinet-induced coloration and resonance before it starts.
Zero Parallel Surfaces
Every internal surface angle is calculated to eliminate standing waves. No internal reflections. No box sound.
Integrated Waveguide
The tweeter’s waveguide is cast directly into the cabinet — not bolted on — enabling a lower crossover point and wider, more consistent dispersion.
Acoustically Inert
When the enclosure stops storing energy, every detail in the recording becomes audible. The cabinet disappears — the music remains.
What’s Inside Matters.
The crossover is the brain of any loudspeaker — and the place most manufacturers cut corners. The Arcus crossover was designed by Danny Richie of GR Research, one of the most respected crossover designers in the audiophile community. Sonicap capacitors. Heavy-gauge US Coils inductors. Pure copper throughout. Hand-soldered connections. No PCB. No shortcuts. Built to Danny’s spec.
Drivers That Deserve the Cabinet.
Neo 3
Planar Magnetic Tweeter
Open, transparent highs with none of the compression or breakup of a conventional dome. Planar magnetic drivers reproduce detail across the full treble range with speed and precision that dome tweeters can’t match.
M165
Mid-Bass Driver
Detailed, controlled bass from a compact enclosure. The M165 delivers clean midrange and low-end extension without the distortion that comes from pushing an undersized driver beyond its limits.

M165
Mid-Bass Driver
Detailed, controlled bass from a compact enclosure. The M165 delivers clean midrange and low-end extension without the distortion that comes from pushing an undersized driver beyond its limits.
Both drivers designed and specified by Danny Richie of GR Research. The drivers, crossover, and enclosure were developed together as a single system — not assembled from off-the-shelf parts.
Three Finishes. One Standard.
Every Arcus enclosure is cast from the same mineral composite. Three distinctive speckle finishes complement the natural texture of the stone beneath.
Sandstone
Slate
Carbon

What Listeners Hear
Trained Ears. No Script.
Danny Richie of GR Research and Ron of New Record Day heard them the morning after assembly. Then two trained listeners, unprompted, compared the Arcus to speakers costing $15,000–$25,000.
Unscripted sessions, recorded in the room. Watch for the reaction — no speaker’s true sound survives a phone mic and web compression.

Howard P.
Audiophile · reference system: Klipschorn AK6 loudspeakers, Lamm tube amplification, Audio Mirror reference DAC
“I’ve heard $25,000 speakers where the snare drum sounded like you were hitting a piece of paper. This has a distinct sound between each instrument — the weight, the density. To me, that’s a very gratifying experience.”Watch Howard’s full session→

“I think these speakers are comparable to really expensive speakers.” — Asked how expensive: “Fifteen to twenty grand. And more.”Watch Ray’s full session→
