PSI Audio introduces the SUB A326-DREX. The new device is intended as a complement for the A226-MAIN monitor speakers. As the A226-MAIN already reaches all the way down to 20 Hz, the SUB A326-DREX is not acting as a subwoofer as much as a Dynamic Range Extender, considerably enhancing the dynamic accuracy and transparency for the spectrum from 20 Hz to 100 Hz. The combination of A226-MAIN and SUB A326-DREX makes for an impressively lifelike listening experience – the real thing.
