The SVS PB-4000 subwoofer thrills action movie fans and audiophiles with staggering output and subterranean deep bass extension down to 13Hz with an amazing degree of subtlety and finesse. A high-excursion 13.5-inch driver and 1,200 watts RMS, 4,000+ watts peak power amplifier with Analog Devices most advanced audio DSP enables variable port tuning and unlocks a smartphone app with advanced DSP and custom presets for precise and convenient tuning. The front-firing 13.5" high output woofer of the SVS PB-4000 powered subwoofer pumps out deep and powerful bass with low distortion, for smooth and accurate performance on music and movies soundtracks. The woofer features a lightweight and rigid composite cone with a premium glass fiber dustcap to generate massive output with pinpoint accurate frequency response. A dual ferrite magnet motor assembly weighing nearly 40lbs generates immense magnetic force and excursion of the 13.5" driver to produce massive low frequency output well below the limits of human hearing. An edge wound 3" voice coil with an eight-layer aluminum flat wire minimizes distortion and power compression while providing excellent heat dissipation and linearity ensuring precise control. The proprietary injection molded gasket and long-throw parabolic surround ensure longevity and allow extreme excursion and SPLs.
Powerful Sledge STA1200D Amplifier
The SVS PB-4000 is a self-powered subwoofer that features a 1,200 watt RMS, and 4000 watts peak power Class D DSP amplifier that controls power flow and ensures crystal clear output no matter what you are listening to and no matter how loud or quiet the volume. It also creates three port tuning modes with their very own response curves -- imagine three subwoofers housed in one cabinet.
iOS and Android compatible
The SVS smartphone app for Android and iOS devices gives you even more control over your listening experience. Download this free app and take control of all of your ported subwoofers DSP functions including: volume, parametric EQ, low pass filter, phase, polarity, room gain, port-tuning, custom presets, and system settings. The app allows you to save favorite settings and presets and displays updates in real time. Whether you want to dial back the bass during a romantic dinner or you want to shake the paintings off the walls with your favorite dance tracks, SVS makes it easy for you to hear every musical detail with dynamic clarity.
Rigid MDF Enclosure
The SVS PB-4000 powered subwoofer features a rigid MDF (Medium Density Fiberboard) cabinet with screw-in rubber feet and a non-resonant steel mesh grille to resist unwanted distortion caused by vibration. A double thick 2" MDF front baffle and rigid internal bracing is used to support the massive drive unit and to ensure an acoustically inert environment. This highly reinforced internal design and acoustic insulation eliminates all coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference volume.
3 Front-Firing Ports
The cabinet utilizes a bass reflex (ported) design with three front-firing 3.5" high-flow ports with inner/outer port flares for smooth bass and high output. Foam port plugs come standard with the PB-4000 and allow for variable tuning. Each response curve for the three port tuning modes; standard, extended and sealed, is fully configured to the respective mode to achieve balanced and accurate low frequency response with all tuning preferences.
Quality Components
This subwoofer pushes the limits of sonic possibility. The SVS PB-4000 features a massive 13.5 inch high-excursion driver, a dual ferrite magnet motor assembly, edge wound voice coils, and an advanced high resolution audio digital signal processor (DSP). All of it is house inside a cabinet featuring a thick MDF front baffle and rigid internal bracing. Technical talk aside, all of these components work together to deliver powerful, clear bass, free of distortion.
Advanced Subwoofer Controls: The PB-4000 subwoofer provides advanced DSP controls, settings, and adjustments.
Balanced & Unbalanced Connections: The SVS PB-4000 is equipped with balanced (XLR) and unbalanced (RCA) inputs and outputs for flexible connectivity. Superior audio quality is ensured with the distinctive noise reduction capability of a balanced connection with XLR jacks.
Active Power Factor Correction (PFC) & Ground Loop Isolation: Active Power Factor Correction (PFC) & Ground Loop Isolation serves as a line conditioner, surge suppressor and voltage regulator letting the amplifier deal with wide voltage fluctuations and ensuring the subwoofers operate flawlessly on any household circuit no matter how unstable the incoming current. An isolated circuit creates a vanishingly low noise floor by eliminating the potential for ground loop hums from outside components resulting in absolute sonic transparency.
Placement Options: Placement of a powered subwoofer is a process driven by competing variables that differ in every home. Décor, floor space, furniture, speaker placement, seating location, and of course, sound quality all factor into the decision of where a subwoofer should be placed. If you have flexibility, there's an artistry to subwoofer placement that can be aided by understanding some basic acoustic principles and set-up techniques.
