Ported box home theater subwoofer with 10-inch high output driver and 300 watts RMS, 700+ watts peak power amplifier, the PB-1000 delivers ground-shaking SPL output and subterranean low frequency extension without sacrificing detail and accuracy. The PB-1000 is an anomaly in the world of subwoofers. It plays below the levels of human hearing, down to 19Hz and lower, yet costs a fraction of what subwoofers with similar low frequency extension and output go for. Simply put, it’s the deepest, most effortless and authoritative bass you’ll find for under $1199.00. No subwoofer comes close to offering this level of low frequency performance value.
