The lowest octaves
Body and weight
It adds body and weight to the lowest octaves without blurring the midrange your main loudspeakers already reproduce well.
Music
Organ, orchestra, bass guitar
Bass guitar, kick drum and pipe organ gain scale and physical presence; orchestral and film recordings recover the floor they were mixed with.
Passive or active
An amplifier matched from the start
Each Zeus is built either passive, driven from your amplifier, or active, with a dedicated Class A or Class D amplifier fitted inside the cabinet.
Made to order
Assembled by hand
A matched woofer, natural acoustic felt, internal wiring and cabinet bracing, assembled by hand; an acoustic resistance panel makes placement in the room far less critical.

From the atelier
The Zeus ‘thunder’ subwoofers
Every model in the Zeus series is what the atelier calls a thunder subwoofer: a compact, hand-built enclosure around a 15-inch woofer with a field-coil (electromagnet) motor wound by Demograf Audio. It adds body and weight to the lowest octaves without blurring the midrange your main loudspeakers already reproduce well.
What it brings to a system
Bass guitar, kick drum and pipe organ gain scale and physical presence; orchestral and film recordings recover the floor they were mixed with. Zeus is a natural partner for high-sensitivity full-range and single-driver loudspeakers driven by low-power tube amplifiers, which rarely reach below 40 Hz on their own.
Passive or active
Each Zeus is built either passive — driven from your amplifier through the speaker terminals — or active, with a dedicated Class A or Class D amplifier fitted inside the cabinet, so the amplifier is matched to the woofer from the start.
Inside the cabinet
Each subwoofer is assembled by hand: a matched woofer, natural acoustic felt, terminals, internal wiring and cabinet bracing — plus the amplifier module in active versions. The standard driver is a Demograf Audio 15-inch woofer on a field-coil motor; other drivers can be fitted to tune the low end to your taste.

- Acoustic resistance panel (aperiodic) as standard — makes placement in the room far less critical
- Open baffle, sealed box, transmission line (labyrinth) or bass reflex on request

Pairs well with
Does the Zeus use tubes?
Zeus has no tubes. The passive version is driven by any amplifier through its speaker terminals, and its field-coil magnets are energised from the mains; the active version carries its own Class A or Class D amplifier and connects via RCA or speaker-level inputs (10 kΩ).
How is the Zeus serviced?
Loudspeakers need no routine service. Drivers, crossovers and terminals are repaired by the atelier for as long as parts exist.
How is it delivered?
Shipping and insurance are paid by the buyer and shown as a separate line in your quotation. Every unit is packed for long-distance transport in heavy-duty flight cases and a wooden crate.
Which mains voltage and plug?
Each piece of gear is built for 100 V, 120 V or 230 V mains with the matching plug (NEMA, Schuko or BS 1363 / type G). The voltage is fixed at order time, so tell us where the unit will be used.
How long does the Zeus take to build?
Build time is six months or more from the queue deposit, depending on the configuration and the queue; delivery takes from one month after completion. The atelier builds seven instruments a year. A priority build is available for an extra 50% of the price: your unit is moved ahead in the build queue.
* Photos are taken from real systems and show the specific configuration of a particular customer; your unit can look the way you want — all our equipment is fully customisable.
