A standout in the subwoofer market, the SVS PB-1000 produces sound below the threshold of human hearing, reaching down to 19Hz and beyond, all while being priced significantly lower than other ported subwoofers with similar low-frequency capabilities. In essence, it delivers the deepest, most effortless, and commanding bass available for under $500. No other subwoofer can match its combination of low-frequency output and value at this price point.
