PSI Audio introduces A326 D-REX for A226 MAIN

Yverdon-les-Bains, 15th July 2025 – The recently introduced main monitor A226 MAIN from PSI Audio already reaches all the way down to 20 Hz. Its new extension hence is not a subwoofer in the typical sense – it functions as a dynamic range extender.

Not a sub, but an extension: A326 D-REX

The PSI Audio A326 D-REX is conceptualized as an extension for the A226 MAIN monitor speakers. As a result, it is not meant to work like other subwoofers, which are generally understood to add low range to a speaker’s spectrum. The A326 D-REX instead works as a Dynamic Range EXtender – hence the “D-REX” part of the name. The device features three 10-inch drivers, covering a range from 20 Hz to 100 Hz – still very subwoofer so far. What makes it different from a sub is how it synergizes with the A226 MAIN.

Big Combination: A226 MAIN and A326 D-REX

The A326 D-REX works in tandem with the A226 MAIN from PSI Audio as if they were one speaker. The Dynamic Range Extender is fully and perfectly aligned with the monitor speaker in both frequency and phase, as if both devices were just one big floorstanding system. Combined, the setup reaches up to 126 dB peak sound pressure – but more importantly, it achieves outstanding dynamic transparency, clarity and power in the low frequencies. With bass this tight and accurate, PSI Audio underlines its claim for the A226 MAIN: This is it. The real thing.

True neutrality breeds compatibility

Like all PSI Audio speakers, the combination of A226 MAIN and A326 D-REX adhere to the ideal of neutral sound recreation. One effect of this principle is the absolute compatibility of PSI Audio monitor speakers across the entire range, making it possible to mix and match speakers for large setups. So while it would certainly be possible to construct an immersive setup completely with A226 MAIN and A326 D-REX, spatial or other constraints may advise to use a variety of speakers: A226 MAIN with A326 D-REX for the front left and right, but then A21-M, A17-M or A14-M for the surrounds and ceiling speakers in an immersive listening environment. Since all PSI Audio speakers accurately reproduce sound, without introducing any additional flavourings, this kind of mixing and matching still keeps the sonic image consistent.

Swiss quality manufacturing

Like all PSI Audio monitor speakers, the A326 D-REX is developed and manufactured by highly trained specialists in the company’s own workshop in Switzerland. Every single speaker and subwoofer is calibrated individually in the anechoic chamber, the resulting graphs are delivered with the devices. The meticulous hand-building of each and every speaker is a testament to the PSI Audio commitment to quality, reliability and longevity.
