From the atelier

Perseus MkII uses Supravox field-coil full-range drivers, so the whole range comes from one diaphragm without a crossover. The treble is silky and detailed, the midrange carries voices and instruments with their real weight, and the stage has depth and air. For larger rooms the same cabinet is built as a three-way system with Fostex horn tweeters and a 10–18 inch woofer. Passive by default, it can also be built with active amplification inside.

The standard cabinet is plywood, MDF or solid wood, painted and lacquered or veneered to order. Internal alloy wiring runs directly to the driver; damping is natural felt.

  • Aperiodic enclosure (acoustic resistive matrix) as standard — easy to place in a room
  • Open baffle, sealed box, transmission line or bass reflex on request
  • Driver surrounds: paper, rubber, foam, Alcantara or cloth

Does the Perseus MkII use tubes?

Perseus has no tubes. Its 93–102 dB sensitivity suits single-ended tube amplifiers as well as solid-state ones.

How is the Perseus MkII 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?

Packing for long-distance transport in heavy-duty flight cases and a wooden crate is included in the price. Shipping and insurance are paid by the buyer and shown as a separate line in your quotation.

Which mains voltage and plug?

The Perseus MkII is driven by your amplifier, but its field-coil drivers need mains power: the electromagnets are energised through a separate supply, built for 100 V, 120 V or 230 V at order time.

How long does the Perseus MkII 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.
