Staggering levels of low-frequency output and subterranean deep bass extension down to 13Hz with an amazing degree of subtlety and finesse to thrill both action movie buffs and audiophiles. Sophisticated DSP technology in the PB-4000 creates three port tuning modes, each with individual response curves to achieve the most accurate in-room frequency response possible. It’s like having three subwoofers in one. Effortlessly powerful bass that extends far below the limits of human hearing, the PB-4000 creates a physical experience with every listening session.
