Four of our earliest designs have been retired and replaced by newer systems. Here is exactly where each one went, and how to reach your original manual.

Legacy Models

Discontinued

Pulsar MKII → Terra

Retired, replaced by our near-field reference monitor.

Pulsar MKII is no longer in production. Terra is its direct successor, built to the same near-field brief with updated drivers, DSP, and calibration.

Discontinued

Quasar MKII → Terra + Gravity

Retired, replaced by our full-range near-field system.

Quasar MKII is no longer in production. The Terra + Gravity system extends Terra to 30Hz linear for the same full-range role Quasar once filled.

Discontinued

Ganymede → Selene + Poseidon

Retired, replaced by our compact full-range system.

Ganymede is no longer in production. Selene paired with Poseidon covers the same compact, full-range role in a smaller footprint.

Discontinued

Titan → Selene

Retired, replaced by our compact coaxial monitor.

Titan is no longer in production. Selene takes over its coaxial monitoring role in a smaller, soffit-friendly cabinet.
