Available at Vinyl Sound in Buffalo, New York, the BP12 is powered by a Purifi amplifier — a Danish-engineered amplifier platform recognized for exceptionally low distortion at high output levels — driven by an Analog Devices DSP processor and Hypex amplifier module, providing 2 × 500 watts continuous power with a frequency response of 20Hz to 150Hz (±3dB) and an LF cutoff of 17Hz at −10dB. The sealed enclosure delivers fast, precise bass transients suited to both music listening and home theater use. Variable crossover frequency from 30Hz to 150Hz, plus an LFE setting at 350Hz, allows integration with a wide range of speaker systems. The free PSB Subwoofer Control app for iOS and Android provides wireless adjustment of crossover frequency, volume, and phase (0°–180°) from any listening position. Built-in IsoAcoustics feet decouple the cabinet from the floor to reduce mechanical interference with room surfaces. The BP12 is part of Vinyl Sound Buffalo's full \u003ca href=\"https:\/\/vinylsound.com\/collections\/speakers\"\u003espeaker collection\u003c\/a\u003e, which covers subwoofers, bookshelf, floorstanding, and powered speakers from leading audiophile brands.\u003c\/p\u003e\n\n\u003ch2\u003eDual 12\" Carbon Fibre Drivers and Purifi Amplification\u003c\/h2\u003e\n\u003cp\u003eThe BP12's dual 12-inch woofers are mounted in opposing positions within the sealed cabinet so that their mechanical motion works in balance, canceling the reactive forces that cause cabinet vibration and coloration in standard subwoofer designs. Each 12-inch driver uses a carbon fibre cone, a high-density rubber surround, a 3½-inch (89mm) voice coil, and a 150 oz magnet structure in a steel basket — a specification associated with extended linear excursion and high thermal capacity. The Purifi amplifier platform applies class-leading open-loop distortion reduction, resulting in clean transient reproduction at volume levels where conventional amplifier designs begin to degrade. The combination of driver design and amplifier technology produces bass that is audibly cleaner at high playback levels than subwoofers using conventional single-driver, class AB amplifier configurations.\u003c\/p\u003e\n\n\u003ch2\u003eApp Control, Connectivity, and Room Integration\u003c\/h2\u003e\n\u003cp\u003eThe PSB Subwoofer Control app for iOS and Android connects to the BP12 via Bluetooth and provides full parameter adjustment without touching the unit — crossover frequency variable from 30Hz to 150Hz, volume level, and continuously variable phase from 0° to 180°. Wired connections include balanced XLR inputs (LFE or left\/right stereo), unbalanced RCA inputs (LFE or left\/right stereo), and a 12V trigger input for integration with automated home theater systems. The 12V trigger enables the BP12 to power on and off automatically with a compatible AV receiver or preamplifier. Auto on\/standby mode activates the amplifier on signal detection and returns to 0.5-watt standby when signal is absent. Universal voltage (100V–240V, 50\/60Hz) and included North American and EU power cords support international use. The automotive-grade paint and clear coat finish is available in Carbon Grey and Basalt Brown.\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\u003e20Hz – 150Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eLF Cutoff (−10dB)\u003c\/th\u003e\n\u003ctd\u003e17Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eContinuous Power\u003c\/th\u003e\n\u003ctd\u003e2 × 500 Watts (1000W total)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAmplifier\u003c\/th\u003e\n\u003ctd\u003ePurifi\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\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eWoofer\u003c\/th\u003e\n\u003ctd\u003e12\" (305mm) Carbon Fibre Cone, High Density Rubber Surround, 3½\" (89mm) Voice-Coil, 150 oz (4252g) Magnet, Steel Basket (× 2)\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 30Hz – 150Hz; LFE Setting 350Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eConnections\u003c\/th\u003e\n\u003ctd\u003eBalanced XLR (LFE or L\/R), Unbalanced RCA (LFE or L\/R), 12V Trigger Input\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eApp Control\u003c\/th\u003e\n\u003ctd\u003eiOS\/Android PSB Subwoofer Control — Volume, Variable Frequency, Phase Control 0°–180°\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eLED Indicator\u003c\/th\u003e\n\u003ctd\u003eRed = Standby, Green = On, Blue\/Red = Bluetooth Pairing\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\u003e18.9\" × 19.3\" × 18.9\" (480 × 490 × 480mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eNet Weight\u003c\/th\u003e\n\u003ctd\u003e132 lb (60 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eShipping Weight\u003c\/th\u003e\n\u003ctd\u003e137 lb (62.5 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eCarbon Grey, Basalt Brown (Automotive Paint \u0026amp; Clear Coat)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFeet\u003c\/th\u003e\n\u003ctd\u003eIsoAcoustics\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 BP12 different from a conventional subwoofer?\u003c\/h3\u003e\n\u003cp\u003eThe BP12 uses two 12-inch woofers mounted in opposing positions inside a sealed cabinet so that their mechanical motion cancels each other's reaction forces. This push-pull configuration reduces cabinet vibration, which is a primary source of coloration and distortion in conventional single-driver subwoofer designs. The result is tighter, lower-distortion bass that tracks music and film transients more accurately. This is combined with a Purifi amplifier — a Danish-engineered platform that achieves exceptionally low open-loop distortion — for clean output at high playback levels.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the Purifi amplifier in the PSB SubSeries BP12?\u003c\/h3\u003e\n\u003cp\u003ePurifi Audio is a Danish audio engineering company co-founded by Bruno Putzeys, who developed many of the foundational switching amplifier concepts now used across the industry. Purifi's amplifier modules are noted for achieving very low distortion figures across the full power range, including at high output levels where conventional class D amplifiers typically exhibit rising distortion. The BP12 pairs the Purifi amplifier module with an Analog Devices DSP processor and Hypex amplifier hardware for real-time driver control and correction.\u003c\/p\u003e\n\n\u003ch3\u003eCan I adjust the PSB BP12 from my phone?\u003c\/h3\u003e\n\u003cp\u003eYes. The free PSB Subwoofer Control app for iOS and Android connects to the BP12 via Bluetooth and provides wireless control of crossover frequency (variable 30Hz–150Hz), output volume, and phase (continuously variable from 0° to 180°). Adjustments made in the app take effect immediately, allowing real-time tuning from any listening position in the room without accessing the subwoofer cabinet directly.\u003c\/p\u003e\n\n\u003ch3\u003eWhat input connections does the PSB BP12 have?\u003c\/h3\u003e\n\u003cp\u003eThe BP12 provides both balanced XLR and unbalanced RCA inputs, each configurable as LFE (single channel) or left\/right stereo. Balanced XLR is the preferred connection for environments where cable runs are long or electrical interference is a concern. The 12V trigger input allows automatic power on\/off when connected to a compatible AV receiver, preamplifier, or amplifier. The subwoofer includes North American and EU power cords and accepts universal voltage from 100V to 240V.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the PSB BP12 come with IsoAcoustics feet?\u003c\/h3\u003e\n\u003cp\u003eYes. The BP12 includes IsoAcoustics isolation feet as a standard feature, not an accessory. IsoAcoustics feet decouple the subwoofer cabinet from the floor surface, reducing mechanical energy transfer between the cabinet and the room structure. This reduces low-frequency standing wave reinforcement and audible room resonance associated with floor-coupled subwoofer placement, resulting in tighter, more focused bass output.\u003c\/p\u003e\n\n\u003ch3\u003eWhat finish options are available for the PSB BP12?\u003c\/h3\u003e\n\u003cp\u003eThe BP12 is available in two finishes: Carbon Grey and Basalt Brown, both applied as a multi-layer automotive paint and clear coat process. Automotive paint finishes provide greater durability and uniformity than standard speaker cabinet vinyl wraps and are resistant to light scratching and surface marking.
