Available at Vinyl Sound in Buffalo, New York, the BP8 is powered by a Hypex nCore Hybrid Digital amplifier — a class D topology recognized for high efficiency and precise driver control at sustained output levels — paired with an Analog Devices DSP processor. The sealed cabinet extends low-frequency output to 20Hz at −10dB with a frequency response of 25Hz to 150Hz (±3dB). Variable crossover frequency from 50Hz to 150Hz, with an LFE setting at 350Hz, allows integration with bookshelf and floorstanding speaker systems of varying bass extension. All adjustments — volume, crossover frequency, and phase (0°–180°) — are accessible directly from the amplifier control panel. Built-in IsoAcoustics isolation feet decouple the BP8 from the floor to reduce mechanical coupling and room resonance. The BP8 is available in Satin Black and Satin White, and is part of Vinyl Sound Buffalo's full \u003ca href=\"https:\/\/vinylsound.com\/collections\/speakers\"\u003espeaker collection\u003c\/a\u003e, which covers subwoofers, powered, bookshelf, and floorstanding speakers from leading audiophile brands.\u003c\/p\u003e\n\n\u003ch2\u003eBipolar Dual 8\" Drivers and nCore Hybrid Digital Amplification\u003c\/h2\u003e\n\u003cp\u003eThe BP8's two 8-inch woofers are mounted in opposing positions inside the sealed enclosure so that their magnetic motor forces work against each other, canceling the reactive forces that typically induce cabinet vibration in standard single-driver subwoofer designs. Each driver uses a woven carbon fibre cone, a high-density rubber surround, a 2½-inch (64mm) voice coil, and a 45 oz (1275g) magnet structure in a steel basket — the same driver design philosophy applied in the PSB Synchrony and Passif 50 speaker ranges. The result is linear, piston-like driver movement across the full output range with minimal coloration from cabinet resonance. The nCore Hybrid Digital amplifier is conservatively rated at 500 watts continuous, providing sustained headroom for dynamic film and music passages without thermal compression.\u003c\/p\u003e\n\n\u003ch2\u003eCabinet Design, Connectivity, and Finish\u003c\/h2\u003e\n\u003cp\u003eThe BP8's sealed cabinet design avoids the port noise and passive radiator distortion associated with ported enclosures, delivering bass that is tight and fast-decaying rather than extended and soft at the low-frequency limit. The compact 13\" × 14\" × 13\" footprint allows placement in environments where full-size subwoofers are impractical. Connections include gold-plated stereo RCA low\/line level inputs and a 12V trigger input for automatic power on\/off with compatible AV receivers and preamplifiers. Auto on\/standby activates the amplifier on signal detection and returns to 0.5-watt Energy Star–compliant standby mode when signal is absent. Universal voltage (100V–240V, 50\/60Hz) and included North American and EU power cords support international use. The Satin Black and Satin White finishes suit both home theater and two-channel listening environments.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eFrequency Response (±3dB)\u003c\/th\u003e\n\u003ctd\u003e25Hz – 150Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eLF Cutoff (−10dB)\u003c\/th\u003e\n\u003ctd\u003e20Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eContinuous Power\u003c\/th\u003e\n\u003ctd\u003e500 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAmplifier Design\u003c\/th\u003e\n\u003ctd\u003eAnalog Devices DSP \u0026amp; Hypex Amp (nCore Hybrid Digital)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eWoofer\u003c\/th\u003e\n\u003ctd\u003e8\" (203mm) Carbon Fibre Cone, High Density Rubber Surround, 2½\" (64mm) Voice-Coil, 45 oz (1275g) Magnet, Steel Basket (× 2, opposing bipolar)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eDesign Type\u003c\/th\u003e\n\u003ctd\u003eSealed\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eCrossover\u003c\/th\u003e\n\u003ctd\u003eVariable 50Hz – 150Hz; LFE Setting 350Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eControls\u003c\/th\u003e\n\u003ctd\u003eVolume, Variable Frequency, Phase Control 0°–180° (Amplifier Panel)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eConnections\u003c\/th\u003e\n\u003ctd\u003eLow\/Line Level Inputs, Gold-plated Stereo RCAs, 12V Trigger Input\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eLED Indicator\u003c\/th\u003e\n\u003ctd\u003eRed = Standby, Green = On\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAuto On\/Stand-by\u003c\/th\u003e\n\u003ctd\u003eYes (0.5W standby, Energy Star compliant)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003eUniversal (100V–240V, 50\/60Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eDimensions (W × H × D)\u003c\/th\u003e\n\u003ctd\u003e13.0\" × 14.0\" × 13.0\" (330 × 355 × 330mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eNet Weight\u003c\/th\u003e\n\u003ctd\u003e42 lb (19.1 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eShipping Weight\u003c\/th\u003e\n\u003ctd\u003e48 lb (22 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFeet\u003c\/th\u003e\n\u003ctd\u003eIsoAcoustics (integrated)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eSatin Black, Satin White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat makes the PSB BP8 different from a standard single-driver subwoofer?\u003c\/h3\u003e\n\u003cp\u003eThe BP8 uses two 8-inch woofers mounted in opposing positions inside a sealed enclosure. When the drivers move in opposing directions simultaneously, their mechanical reaction forces cancel each other rather than transferring into the cabinet walls. This eliminates the cabinet vibration that causes coloration and distortion in conventional single-driver designs. The sealed enclosure adds a second layer of isolation by removing the port or passive radiator openings through which conventional subwoofers introduce mid-bass noise and group delay distortion. The combination produces bass that tracks transients accurately at all playback levels.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is nCore Hybrid Digital amplification in the PSB BP8?\u003c\/h3\u003e\n\u003cp\u003enCore is a high-efficiency class D amplifier topology developed by Hypex Electronics in the Netherlands. It applies a feedback architecture that achieves very low output impedance and distortion across the full power bandwidth, allowing the amplifier to maintain tight control of the driver's voice coil at high excursion levels. In the BP8, the nCore output stage is paired with an Analog Devices DSP processor that applies digital signal processing to driver correction and crossover filtering before the analog amplifier stage, providing more precise control than analog-only subwoofer amplifier designs.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I connect the PSB BP8 to my system?\u003c\/h3\u003e\n\u003cp\u003eThe BP8 connects via gold-plated stereo RCA inputs that accept low-level or line-level signals from an AV receiver's subwoofer output, a preamplifier's low-frequency output, or a stereo amplifier's speaker-level output through a high-level adapter. A 12V trigger input accepts a trigger signal from compatible AV receivers and preamplifiers to turn the subwoofer on and off automatically with the rest of the system. Crossover frequency, volume, and phase are adjusted using the controls on the amplifier panel.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the PSB BP8 have smartphone app control?\u003c\/h3\u003e\n\u003cp\u003eNo. Unlike the larger SubSeries BP12, the BP8 does not include Bluetooth or smartphone app control. Crossover frequency (variable 50Hz–150Hz), volume level, and phase (0°–180°) are adjusted using the controls mounted directly on the amplifier panel. For listeners who prefer wireless parameter adjustment from the listening position, the BP12 offers the PSB Subwoofer Control app via Bluetooth.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the PSB BP8 include IsoAcoustics feet?\u003c\/h3\u003e\n\u003cp\u003eYes. IsoAcoustics isolation feet are integrated as a standard feature of the BP8 cabinet, not a separate accessory. IsoAcoustics feet decouple the subwoofer from the floor surface, reducing the mechanical energy transfer that causes low-frequency standing wave reinforcement between the cabinet and the room. In practice, this reduces the audible \"boom\" associated with floor-coupled subwoofer placement and produces tighter, more defined bass from any floor surface type.\u003c\/p\u003e\n\n\u003ch3\u003eWhat finish options are available for the PSB BP8?\u003c\/h3\u003e\n\u003cp\u003eThe BP8 is available in Satin Black and Satin White. Both finishes use a satin-level surface sheen that reduces surface reflection compared to gloss-finish cabinets and is less prone to showing fingerprints or fine scratches. The compact 13\" × 14\" × 13\" footprint and clean cabinet lines allow the BP8 to blend into both dedicated home theater and living room two-channel listening environments.\u003c\/p\u003e\n\n\u003ch3\u003eWhere to buy PSB SubSeries BP8 in Buffalo NY?\u003c\/h3\u003e\n\u003cp\u003eThe PSB SubSeries BP8 is available from Vinyl Sound, an authorized PSB Speakers dealer in Buffalo, New York.
