PSB has set itself an ambitious goal of introducing an active subwoofer that can "eliminate low-frequency distortion and unwanted resonances in home theater." To achieve all this, the PSB emphasizes 3 points: an 8-inch woofer with reverse bipolarity; 500W exclusive amplifier built by NCORE technology; Isolation treatment including isoacoustics isolation feet. Through these initiatives, we hope to transform the user experience of movies, ** and gaming apps with "deep and powerful low frequencies and unmatched accuracy." ”
Suppressing unwanted vibrations keeps low frequencies crystal clear. BP8's proprietary reverse bipolar dual 8-inch subwoofer is housed in a rugged, soundproof, sealed cabinet that delivers distortion-free bass down to 20Hz. The configuration of the opposite direction of the driver eliminates vibration and ensures that the electrical signal is effectively converted into the original acoustic output. In the past, the use of bass reflex holes or passive radiators caused noise and distortion, so BP8 completely eliminated them. With the integrated isoacoustics isolation feet, it is also seamlessly separated from the vibrations and resonances generated in the room for a pure, distraction-free sound experience.
Inspired by the driver design of the Synchrony and Passif 50 loudspeakers, the drivers in the BP8 feature a linear piston movement that provides the best efficiency and power handling. Dual 8-inch unit with carbon fiber woven basin and rounded rubber surround as well as 2A 5-inch ultra-high-power voice coil and a sturdy 45-ounce magnet construction work together to deliver accurate and detail-filled low frequencies. 
With the blessing of NCORE technology, the BP8's hybrid digital amplifier is conservatively labeled as 500W, but when big dynamics** come, it can provide powerful output power. In addition to its abundant power, its sound performance is very refined, allowing for highly precise control of the unit's movements. 
Looking at the BP8's form factor, the W330 H355 D330mm is compact, but they have the strength to challenge the larger subwoofer. The sleek look under the black and white finish package is also very easy to integrate into the home environment.
