Monitor architecture
Built for the point where listening becomes a decision.
PRO ONE translates research from Microphase's Tower 3 and Tower 4 Signature loudspeakers into a compact format for professional rooms. Its active bass system, proprietary midrange and AMT tweeter are arranged to reveal the relationships that shape a mix: weight, timbre, placement and texture.
A dark-grey high-pressure laminate gives the monitor a durable studio surface. Chamfered edges expose the birch-ply structure beneath, keeping the link to Microphase's consumer loudspeakers visible.
Professional monitoring with a French acoustic lineage and an Australian signal path.
One integrated system
Drivers, crossover and amplification developed as a whole.
The published architecture combines specialist components from France, Germany and Australia in a cabinet built by Microphase.
Paper-cone presence.
A proprietary 13 cm Audax bass-midrange driver uses a paper cone and phase plug to cover the region where tonal judgements often live.
Mundorf AMT detail.
A 5.5 cm Mundorf air-motion transformer crosses passively from the midrange at the published 3.5 kHz point.
Australian amplification
Two channels. One coherent monitor.
The bespoke 2 × 100 W MosFET class A/B plate amplifier is made by Holton Audio in Tasmania. One channel drives and filters the bass system; the second drives the midrange and tweeter cell full range through its passive crossover.
Microphase calls the combination of French acoustic thinking and Tasmanian amplification the “Méthode Tasmanoise”.
