Listen to the Room

Remove the box
The room becomes the loudspeaker
An open-back dipole loudspeaker radiates sound in two directions simultaneously. This contributes to a sense of acoustic depth that mirrors how acoustic instruments behave in real space. You hear not just where sounds are, but the environment they exist within. It is the fundamental reason open-baffle speakers produce a soundstage that closed-box designs cannot replicate.

Built from the best

Each component is the singular best option for its role in the system
Architectural Concrete Baffle
Our bespoke concrete baffle is engineered for acoustic mass and achieves the internal damping characteristics of materials twice its weight. Concrete's crystalline structure scatters internal resonances resulting in an open cabinet that is acoustically inert at frequencies most critical to sonic clarity.

Ferro Steel Stand

The 6mm cold-rolled steel stand is engineered to transfer the concrete cabinet's full mass to the floor without resonant coupling; its structural self-leveling geometry was chosen for rigidity, not aesthetics alone.

SEAS Fabric Dome Tweeter

SEAS fabric dome tweeters represent the Norwegian tradition of acoustic precision. The silk dome diaphragm operates with a controlled break-up mode well above audible frequencies, ensuring linear pistonic motion through the entire treble band. The double magnet system provides the flux density required for the sensitivity demanded by passive dipole designs.

Satori Midrange Driver

Denmark's Satori midrange driver is the instrument upon which vocal performances, acoustic guitar, and orchestral strings will be judged. Egyptian papyrus fibre cones offer a combination of stiffness and internal damping unavailable in synthetic materials. The extended copper sleeve beneath the voice coil linearises inductance across the frequency range, eliminating the subtle harmonic distortions that betray lesser drivers at moderate listening levels.

15" Neodymium Woofer

Made in the USA, Eminence's neodymium woofers set the standard for professional subwoofer performance in live sound reinforcement. In a dipole configuration, the woofer's linear excursion capability and neodymium flux density produce bass with a character rare in domestic audio: tight, articulate, and dynamically uncompressed.

Acoustically transparent cloth

The removable cloth frame is specified for acoustic transparency — its weave density calibrated to pass the full frequency range without attenuation or coloration.

Our Crossover

Where the system becomes greater than the sum of its parts
The soundstage you hear — its depth, its imaging, the precise placement of instruments in space — begins inside the crossover. It routes each frequency to its designated driver and ensures the sound from each arrives at the listening position in perfect phase alignment. Without that alignment, three world-class drivers tell three slightly different stories. With it: three drivers, one voice.

Plays well with others

Connects to what you have
Our passive loudspeaker works with your existing amplifier — no onboard electronics, no proprietary requirements. It is also highly efficient, designed to perform from 50 watts per channel, making it compatible with a wide range of source and amplification setups without modification or upgrade. The open-back dipole configuration is forgiving of non-ideal listening environments and less sensitive to room placement than conventional enclosed designs. Connect it to what you have. Place it where it works. It will perform.
