Thunderous low frequency output and extreme deep bass extension, with accuracy and control, the PB-4000 is a benchmark setting subwoofer on every level with unheard-of performance and features for even double the price.

With the PB-4000, it’s like having three subwoofers in one. Effortlessly powerful with bass that extends far below the threshold of human hearing, the PB-4000 creates a revelatory experience with every movie and music listening session.
Setting all performance benchmarks for ported subwoofers in its class, PB-4000 unleashes heart-pounding output and infrasonic deep bass extension with pinpoint accuracy. Brutally powerful yet subtle and nuanced, you’ll never think of bass the same way again.
