Add powerful bass to your home entertainment experience with the black ash SVS PB-4000 13.5" 1200W Subwoofer. It uses a 13.5" front-firing woofer to produce up to 1200W of RMS power and up to 4200W of peak power for ground-shaking performance in nearly any listening environment. It features three bass ports and an adjustable minimum frequency response between 13, 16, or 18 Hz, making the PB-4000 equipped to handle virtually all types of listening material.
Amplifier Designed for Enhanced Output, DSP, and Power Management
Discrete MOSFETs with Class D Amplification with the Sledge STA-1200D Amplifier
The efficiency of Class D amplification is combined with the augmented current of the discrete MOSFETs to help enable immense low frequency output and precise driver control for enhanced performance at nearly all drive levels.
50 MHz Analog Devices DSP
The digital processor is designed to maintain accuracy and sound quality through in-room tuning, enhanced frequency response curves, DSP controls, and more.
- Room Gain – Tailors the roll-off slope to the acoustics of the room for enhanced frequency response accuracy and deep in-room extension without the "boominess" commonly associated with room gain.
- Port Tuning – Each response curve for the three port tuning modes (standard, extended, and sealed) is configured to the respective mode for balanced and accurate frequency response.
- Advanced Limiting – Allows the amplifier to deliver its maximum power and maximize on the driver's potential with high output and virtually no distortion.
Active Power Factor Correction (PFC)
Active PFC serves as a line conditioner, surge suppressor, and voltage regulator, letting the amplifier handle wide voltage fluctuations and helping to ensure that the subwoofer operates flawlessly on nearly any household circuit, regardless of incoming current instability. An isolated circuit creates a low noise floor by virtually eliminating the potential for ground loop hums from outside components for enhances sonic transparency. It lowers the average current and smoothes the power input current, allowing for a 1200W output from a traditional 15A power outlet.
Driver Features
Dual Ferrite Magnet Motor Assembly
The motor assembly is designed to generate immense magnetic force and excursion of the 13.5" driver to produce massive low frequency output below the typical limits of human hearing.
Edge-Wound Voice Coil
The edge-would voice coil features an eight-layer aluminum flat wire to help minimize distortion and power compression while augmenting heat dissipation, linearity, and overall driver control.
Lightweight, Rigid Composite Cone
The cone features a lightweight, rigid design with a glass fiber dustcap for enhanced output with accurate frequency response.
Injection-Molded Gasket and Long-Throw Parabolic Surround
The injection-molded gasket and long-throw parabolic SBR surround are engineered to help ensure proper pistonic motion and longevity for enhanced accuracy & control, and higher excursion & SPLs.
Acoustically Inert, Rigidly Braced Cabinet Design
2" MDF Front Baffle and Internal Bracing
The 2"-thick MDF front baffle and rigid internal bracing are designed to support the drive unit and help ensure an acoustically inert environment for the driver.
Reinforced Internal Design
The reinforced internal design and acoustic insulation are engineered to eliminate all coloration or resonance from the cabinet, even when outputting the deepest low frequencies at high volumes.
Steel Mesh Grille
The protective, non-resonant steel mesh grille and elastomer feet are designed to reduce noise artifacts within the room.
Copper Ring Shorting Sleeve
The copper ring shorting sleeve is designed to reduce gap induction and distortion, enhancing thermal conductivity.
Oversized Low-Carbon Steel U-Yoke
The oversized low-carbon vented steel U-yoke and top plate are engineered to provide superior cooling and improved magnetics for enhanced performance and efficiency.
Copper and Nomex Composite Leads
Dual 24-strand copper and Nomex composite high-temperature leads woven through the suspension help provide an enhanced electrical connection from the amplifier to the voice coil.
High-Density, FEA-Optimized, Cast-Aluminum Basket
The FEA-optimized, cast-aluminum basket is designed to provide enhanced levels of rigidity, tensile strength, and energy transference.
Narrow-Tolerance Suspension Materials
Machined motor elements and narrow-tolerance suspension parts help produce augmented linearity at full excursion for a tight and fast output, even at high volumes.
Front-Mounted LED Display
IFC (Intelligent Feature Control) is built into the blue dimmable, 8-digit, front-mounted, LED display, which can also be disabled.
Simple Control with the 4000 Series Smartphone App
Bluetooth Connectivity
Compatible with iOS and Android devices, the app connects via Bluetooth for convenient control, even when the subwoofer is placed out of sight. Adjust the low pass filter, phase, polarity, port tuning, custom presets, system settings, and more.
Parametric EQ Controller
The three-band parametric EQ controller allows precise adjustments for frequency slope and Q-factor down to the single Hz level with four different slopes, so you can enhance performance by eliminating peaks, nulls, and other room issues.
Real-Time Feedback
Two-way feedback shows updates in real time on both the app and the subwoofer interface.
