PSI Audio presents A226-MAIN three-way main monitor with symmetrical woofer configuration and all-new tweeter

Yverdon-les-Bains, 7th May 2025 – PSI Audio presents the new three-way main studio monitor A226-MAIN. Combining all the PSI Audio qualities and sizing them up, the A226-MAIN is the ideal monitoring system for high-end studios.

The Big One: A226-MAIN

PSI Audio A226-MAIN is the largest speaker the Swiss manufacturer has ever developed. This monitor was developed primarily for mastering purposes. Two 10-inch membranes for the lows, complemented by midrange driver and tweeter, all in a solid, fully reinforced double MDF enclosure – the A226-MAIN means business. The four power amps with 500 W (2 x 250 w), 150 W, and 65 W amplify the frequency range from 20 Hz to 23 kHz (-6 dB) to 112 dB (at 1 m according to the new AES 75 standard) and up to 126 dB peak. The fine art of PSI Audio lies in making these components work together in a way that creates the most accurate sound image to date, reproducing audio exactly as it was originally captured. This is it. The real thing.

Peak driver technology for absolute fidelity

Its size is but one of the things that set the PSI Audio A226-MAIN apart. Every detail is a superlative in itself. Take the high-frequency driver: PSI Audio developed an all-new aluminium coil dome tweeter to accurately depict every detail in the highs. For the midrange, the engineers in the Swiss manufacture already had their renowned EXD driver from the A25-M available. For the lower frequencies, the A226-MAIN employs two woofers of 10 inches in diameter each, which are driven by the same signal, making the speaker a three-way system. The double flow guide bass reflex ensures a deep and powerful bass without air turbulence or noise.

Symmetrical setup, orientable stand and rotatable baffle

In the PSI Audio A226-MAIN, the transducers have been arranged in a specific way. The two woofers are placed in a symmetrical configuration on either side of the mid-high baffle, which can be rotated as required. This configuration and the waveguides achieve a limitation of vertical dispersion and a wide sweet spot. There is also a stand designed specifically for this monitor to allow optimum orientation at all times.

Proprietary technology: PSI Audio Greatest Hits

As the new flagship monitor speaker, the A226-MAIN combines all the proprietary technology that already made the smaller PSI Audio speakers the most accurate monitor speakers. Compensated Phase Response (CPR) ensures perfectly aligned audio reproduction of the different ways, Adaptive Output Impedance (AOI) monitors membrane movement and optimizes transients. The powerful Class G/H amplifiers efficiently drive the system with high SPL output and low distortion. The technology is entirely and 100 percent analogue to guarantee accurate reproduction and avoid latency times. All these innovations combine to provide precise audio playback – the perfect listening tools for discerning professionals.
