Design & Build Quality of the SVS PB-4000
The SVS PB-4000 stands as a perfect blend of craftsmanship, technology, and durability. Its massive MDF cabinet, reinforced with extensive internal bracing, eliminates unwanted vibrations, ensuring pure, distortion-free bass. The ported design uses triple 4-inch flared ports, optimized for airflow and minimal turbulence, allowing you to enjoy immense low-frequency output with remarkable clarity.
Available in Premium Black Ash and Piano Gloss Black finishes, it complements any home theater or living room setup. The front-firing 13.5-inch driver, protected by a sturdy steel mesh grille, adds visual impact while emphasizing performance. Every design element — from the cabinet proportions to the amplifier layout — reflects SVS’s precision engineering philosophy.
This subwoofer doesn’t just look powerful — it is powerful, yet refined enough to blend naturally into any high-end environment.
Power Output & Performance
At the heart of the SVS PB-4000 lies a 13.5-inch high-excursion driver powered by a Sledge STA-1200D amplifier delivering 1,200W RMS and over 4,000W peak output. This combination produces enormous bass with surgical precision. The driver’s dual ferrite magnet motor system and edge-wound voice coil ensure massive cone movement with minimal distortion.
The frequency response extends from 13Hz to 200Hz (±3dB), providing both deep subsonic extension and accurate midbass. Whether it’s the low rumble of explosions or the resonant tones of a cello, the PB-4000 maintains control and linearity at all levels.
The subwoofer’s DSP control allows real-time tuning, ensuring the perfect balance of output, clarity, and dynamics. The result is breathtaking — cinematic bass that feels alive yet stays clean and balanced.
Advanced Technology & Features
Packed with advanced engineering, the SVS PB-4000 employs the same digital processing power as SVS’s flagship models. Its Analog Devices 50 MHz DSP offers precise tuning over crossover points, phase alignment, and room EQ. The SVS smartphone app, available for Android and iOS, enables remote control of settings like volume, parametric EQ, polarity, and custom presets.
The Class D Sledge amplifier with discrete MOSFET output delivers enormous current with ultra-low distortion. This combination ensures fast, tight, and responsive bass, even at extreme volume levels.
The PB-4000 also features custom presets for movies, music, and night listening modes — making it adaptable to your preferences and environment. Together, these technologies create a listening experience that’s immersive, controlled, and effortlessly powerful.
