PSB SubSeries BP8 Subwoofer

What You Need to Know

Bass Without the Shake

The SubSeries BP8 is a game-changer in precision bass. Instead of one big driver pounding the cabinet in a single direction, PSB mounts proprietary dual 8-inch drivers on opposite sides in a bipolar, force-canceling arrangement: each driver's motion cancels the other's reaction forces, so the sealed cabinet stays essentially inert. What's left is pure, distortion-free bass reaching down to 20Hz—without the buzz, rattle, and smear that cabinet vibration adds to ordinary subwoofers.

Serious Driver and Amplifier Engineering

Each 8-inch driver uses a woven carbon fiber cone, filleted rubber surround, a 2.5-inch ultra-high-power voice coil, and a robust 45-ounce magnet structure—built to move serious air with total composure. Driving them is a conservatively rated 500-watt continuous HybridDigital amplifier built on renowned nCore technology, prized in high-end amplification for vanishingly low distortion and iron-fisted control.

Isolated from Your Room, Easy in Your System

Genuine IsoAcoustics isolation feet decouple the BP8 from the floor, preventing low-frequency vibrations from bleeding into your room and muddying the sound—the finishing touch on a design obsessed with eliminating resonance. At roughly a 13-inch cube, it tucks in almost anywhere, connects via gold-plated LFE/line-level RCA inputs with a variable 50-150Hz crossover and phase control, and includes a 12-volt trigger for system integration. Available in Satin Black or White.

Frequently Asked Questions

Why two 8" drivers instead of one big one?

Physics. Two opposing drivers move in perfect opposition, so the reaction forces that normally shake a subwoofer's cabinet cancel out. You get the cone area of a much larger sub with none of the cabinet vibration—bass that's deep, quick, and clean rather than boomy.

What are the IsoAcoustics feet for?

IsoAcoustics is the industry leader in audio isolation. Their integrated feet keep low-frequency energy from transferring into your floor, which prevents room rattle, protects clarity, and helps keep the peace with downstairs neighbors.

Is it good for music as well as movies?

Especially for music. The sealed, force-canceled design and nCore amplification favor speed and pitch accuracy—the qualities that make bass musical—while 500 watts and 20Hz extension provide plenty of theater impact.

How do I connect it?

Use the LFE input from a home theater receiver or processor, or the line-level RCA inputs from a preamp with the built-in 50-150Hz crossover handling the blend. The 12V trigger lets the BP8 power up and down with the rest of your system. Ask us if you're unsure about your setup.
