PSB SubSeries 450 subwoofer

The SubSeries 450 Subwoofer is PSB's flagship audiophile subwoofer with the highest level of bass performance to date. Using a Class D amplifier and DSP technology to bring the frequency response down to 20 Hz, the SubSeries 450 can amplify the incredible explosions of movie soundtracks with precision and accuracy. It also delivers deep, detailed bass with ultra-low distortion for a bigger, more amphitheatrical soundstage that lets you feel the thump of the bass drum and heavy cinematic footsteps lurking nearby.
