From the atelier

Cassandra MkII is a floorstanding loudspeaker with a monitor’s precision: it shows what is on the recording without sounding cold or becoming tiring. The low/mid driver is a BEAG HX-302 with a paper cone and cobalt magnet; the treble comes from a SICA high-efficiency tweeter through a simple second-order crossover at 3.5 kHz. The horn-loaded tweeter and the stepped-forward woofer are aligned in time, which keeps the image precise and three-dimensional. The rear port takes the bass down to 28 Hz, and 95 dB sensitivity lets it work from 3 W tube amplifiers.

Does the Cassandra MkII use tubes?

Cassandra has no tubes. As little as 3 W of amplification is enough, so it pairs naturally with single-ended tube amplifiers.

How is the Cassandra 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?

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?

The Cassandra MkII is passive and does not connect to the mains. Only the amplifier you pair it with needs the right voltage.

How long does the Cassandra 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.
