THE COMPLETE SYSTEM
Precision expands.
Performance remains.
Build the monitoring system around your room – from the A226-MAIN alone to a complete full-range reference with the A326 D-REX and remote APA-700 amplification. Its 100% analogue signal path, without DSP, preserves the accuracy required for mixing, mastering and tracking.

HEARD IN THE STUDIO
“These are the most accurate speakers
I have heard with my own ears.”
KADILLAC STUDIOS · REFERENCE MONITORING ENVIRONMENT
DYNAMIC RANGE EXTENDER
A326
D-REX
Three 10-inch drivers extend dynamic transparency from 20 to 100 Hz – without behaving like a conventional subwoofer.
REMOTE AMPLIFICATION
APA-700
External Class G/H analogue amplification makes controls accessible when the A226-MAIN is soffit-mounted.
EXTENDED DOME DRIVER
The midrange
without a blind spot.
The hand-built EXD midrange driver combines cone control with dome speed. Together with the handmade tweeter and flat frequency response, it delivers lower distortion, higher SPL and the precise stereo image required for critical listening.
INDIVIDUALLY CALIBRATED
Flat by design.
Proven by measurement.
Every A226-MAIN is individually measured and calibrated in PSI Audio’s full-size anechoic chamber. Each monitor leaves the factory with its own frequency-response certificate – a unique record of its Swiss-made precision.
Example of an individual calibration curve. The certificate supplied with each monitor reflects that specific unit.
TECHNICAL DATA
Measured.
Not imagined.
COMPLETE TECHNICAL DATA
Every number.
Nothing hidden.
Detailed published specifications for system designers, studio consultants and engineers planning a critical monitoring environment.
FLAT RESPONSE
Accuracy before character.
A studio monitor should reveal the mix, not flatter it. The A226-MAIN maintains a neutral frequency balance so engineers can judge level, EQ, dynamics and spatial placement without boosted bass, softened mids or artificial brilliance.
HANDMADE IN SWITZERLAND
Precision built by hand.
Every A226-MAIN is developed, assembled, measured and individually calibrated at PSI Audio in Switzerland. Components are matched and adjusted by skilled specialists so tolerances cancel each other instead of accumulating.
A226-MAIN · WHO IS IT FOR?
One reference.
Every critical decision.
The A226-MAIN is designed for environments where absolute accuracy, full-range extension and reliable translation are essential. With sufficient listening distance, it supports both professional production and demanding personal listening.
“The first time I heard them, I couldn’t believe my ears. Everything is precise — the stereo image, the bass and the natural depth of the midrange.”
Santiago Fernandez · First Floor Studio

A226-MAIN · PRECISION AND POWER REDEFINED
A reference main monitor
for every critical decision.
The PSI Audio A226-MAIN is a three-way active main studio monitor engineered for uncompromising full-range accuracy, headroom and transparency. Its fully analogue signal path reveals every nuance without coloration, from deep controlled bass to the finest transient detail.
Designed for large control rooms, mastering suites and professional recording studios, it is a trusted reference for mixing, mastering, tracking, broadcast, post-production, immersive audio and demanding personal listening.
Each A226-MAIN is developed, handmade, individually measured and calibrated in Switzerland. Flat frequency response, precise phase response and a stable stereo image let engineers work confidently at every listening level.
