SVS PB4000 - Subwoofer

Bass reflex powered subwoofer, 13.5" long-excursion driver, 1200 W RMS, 4000 W peak, DSP

The SVS PB4000 subwoofer thrills action fans and audiophiles with jaw-dropping performance, deep bass extension down to 13Hz, incredible articulation and precision. A 13.5-inch high-excursion driver, a 1,200-watt RMS and over 4,000-watt peak amplifier, and even more advanced DSP by Analog Devices enable variable port tuning and full control via a dedicated smartphone app.

Delivering low-frequency output and extremely deep bass with precision and control, the PB-4000 is a subwoofer with reference-level performance at every level and features unheard of even at twice its price. The sophisticated DSP amplifier creates three port tuning modes, each with individual response curves to achieve the most accurate frequency response possible in your environment. With the SVS PB-4000, it's like having three subwoofers in one. Effortlessly delivering bass that extends far below the threshold of human hearing, the SVS PB-4000 creates a revelatory experience in every movie and music listening session.

Jaw-dropping bass extension and output with pinpoint control and accuracy

The SVS PB-4000 combines seismic power and unfathomable low-frequency extension that you can feel with refinement and musicality that suspends your sense of disbelief. With technology taken from the SVS 16-Ultra Series, the world’s best subwoofers according to nearly every audio publication, the SVS PB-4000 redefines expectations and delivers an unrivaled level of subwoofer performance available only from SVS.

SVS High-Excursion Driver - Legendary output and control, typical SVS

The PB-4000 driver harnesses the full potential of the Sledge STA-1200D amplifier's enormous power with precision and control to produce energizing room SPLs and effortless low-frequency extension with pinpoint accuracy at all power levels.

• The nearly 40-pound dual ferrite magnet motor assembly generates massive magnetic force and 13.5-inch driver excursion to produce massive low-frequency output well below the limits of human hearing.
• The eight-layer aluminum flat wire voice coil minimizes distortion and power compression, while providing excellent heat dissipation and linearity for precise control.
• The lightweight and rigid composite cone with high-quality fiberglass duster generates enormous power with a crisp and precise frequency response.
• The patented injection gasket and long-range parabolic coating ensure longevity and allow for extreme excursions and SPLs.

Sledge Amplifier - Extreme Power, Sophisticated DSP, Advanced Power Management

Conservatively rated at 1200 Watts RMS and over 4,000 Watts Peak Power, the ST-1200D S-PB-4000 amplifier utilizes an efficient Class D design combined with a fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is an effortless level of power and advanced processing not available from any other powered subwoofer manufacturer.

High current output stage, fully discrete MOSFETs with Class D amplification efficiency

Class D amplifier efficiency with the ability to move massive amounts of current through fully discrete MOSFETs allowing immense power output and precise control for exceptional subwoofer performance in real-world use at all output levels.

Sophisticated DSP Analog Devices at 50Mhz with high resolution

The most advanced digital processor ever used in a subwoofer maintains pinpoint accuracy and pristine sound quality through meticulous anechoic chamber tuning, optimized frequency response curves, powerful DSP controls and more.

Variable port optimization mode

Foam port caps come standard with the PB-4000 and allow for variable adjustment. Each response curve for the three port tuning modes; standard, extended and sealed, is fully configured for its respective mode to achieve balanced and accurate low frequency response with all tuning preferences.

Active Power Factor Correction (PFC) & Ground Loop Isolation

It functions as a line conditioner, surge protector and voltage regulator allowing the amplifier to handle large voltage fluctuations and ensuring that the subwoofers will operate perfectly on any household circuit, no matter how unstable the input current. An isolated circuit creates a silent floor that completely eliminates the potential for ground loop hum from external components resulting in absolute acoustic transparency.

PB-4000 Smartphone App – Easiest Way Ever to Manage Subwoofer DSP and Control

The revolutionary smartphone app works with Apple iOS® and Android® devices to unleash the full depth, punch and nuance of the PB-4000 subwoofer by controlling all DSP functions, including volume, parametric EQ, low-pass filter, phase, polarity, room gain, port tuning, custom presets and system settings.

• It connects via Bluetooth for convenient control even when the subwoofer is out of sight.
• The 3-band parametric EQ controller allows precise adjustments for frequency slope and Q factor down to the single Hz level with four different slopes, so users can improve performance by eliminating peaks, nulls and other space issues.
• Store 3 custom presets for movies, music, and other listening experiences like sports or gaming.
• 2-way feedback shows real-time updates on both the app and subwoofer interface

Acoustically Inert and Rigidly Braced Ported Box Cabinet Design

An inlaid front panel display, three front-facing high-output bass ports, rounded edges and a curved metal grille on the PB-4000 cabinet give it a refined yet imposing look that visually blends in with home theater and high-end systems.

• Dual 2-inch MDF front panels and rigid internal bracing support the massive drive unit and ensure an acoustically inert environment.
• The highly braced internal design and acoustic isolation eliminate any coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference volume.
• Non-resonant steel protective grille and custom elastomer feet to reduce noise artifacts within a room.
• 2-way feedback shows real-time updates on both the app and subwoofer interface
