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.
