A326 D-REX
Extending Bass Reality.
The A326 D-REX is the perfect companion to PSI Audio’s flagship A226-MAIN monitor: a dedicated Dynamic Range Extender designed to elevate accuracy and realism in the lowest octaves. Rather than functioning as a traditional subwoofer, the A326 D-REX extends and enhances the dynamic response between 20 Hz and 100 Hz (160 Hz with LFE option), unlocking unprecedented precision and control in the bass spectrum. By pairing the A226-MAIN’s full-range clarity with the D-REX’s deep extension, engineers gain a monitoring system that combines explosive power with absolute transparency. The result is a breathtakingly lifelike listening experience – faithful, effortless, and uncompromising.

The perfect and most powerful low end in your studio
Given enough power, going low with a speaker is not too much of a challenge. Reproducing low frequencies with precision, however, is a different matter entirely. The PSI Audio A326 D-REX brings a whole new dimension of accuracy to the low end.
PSI Audio has translated its general approach of unaltered, maximum fidelity reproduction to the bass spectrum, allowing for a riveting experience that will change the way you work. Taking the guesswork out of the bass management, the A326 D-REX grants an accurate representation of what is really going on “down below”. Take control and create a sonic wonderland that reaches throughout the entire spectrum with no insecurities and no need to double-check your work on a different system. Get a subwoofer you can trust.

“These are the most accurate speakers I have heard with my own ears.
Listening to them, especially for extended periods of time, is truly a revelation. “

Each speaker is individually calibrated in our anechoic chamber and is delivered with its frequency response sheet. A proof of quality.
Handmade in Switzerland
All our products are handcrafted in Switzerland with passion and attention to detail.
Manufacturing by hand allows to match and adjust components so that tolerances cancel each other out instead of building up, as is often the case in industrial production.
A326 D-REX – Who is it for?
Designed to complement our largest three-way A226-MAIN, the A326 D-REX packs a lot of power to support full-range listening without compromise. An LFE option is also available, extending the frequency range from 20 Hz to 160 Hz. It makes it compatible with the Dolby Atmos requirements.
The A326 D-REX is at home wherever low frequencies need to be monitored reliably, like in mixing, mastering and post-production.
