Proprietary injection molded gasket and long-throw parabolic surround ensure longevity and allow extreme excursion and SPLs.

Sledge Amplifier – Massive Output, Sophisticated DSP, Advanced Power Management

ubwoofer manufacturer.

High Current Output of Fully Discrete MOSFETs with Efficiency of Class D Amplifier
Efficiency of a Class D amplifier with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense output and precise control for outstanding real-world subwoofer performance at all drive levels.

Sophisticated 50Mhz High Resolution Analog Devices Audio DSP
Most advanced digital processor ever used in a subwoofer maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning, optimized frequency response curves, powerful DSP controls and more.

Variable Port Tuning Modes
A single foam port plug come standard with the PB-4000 and allow for variable tuning. Additional port plugs are available upon request to support all tuning options*. 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.

*Since the vast majority of SVS subwoofer owners never use the port plugs and many end up in landfills, we’ve made them optional to be a bit more eco-conscious. We are happy to send port plugs free of charge if they will be used, just note in the special instructions during checkout.

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.

Acoustically Inert and Rigidly Braced Sealed Box Cabinet Design

Inlaid front panel display, rounded edges and a curved metal grille on the sealed box SB-4000 cabinet give it a refined yet commanding look that blends visually with home theaters and high-end audio systems. It’s sealed cabinet design results in tighter, more musical bass and make it significantly more compact than ported box subwoofers with similar specs.

Double thick 2-inch MDF front baffle and rigid internal bracing to support the massive drive unit and to ensure an acoustically inert environment.
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.
Protective, non-resonant steel mesh grille and custom elastomer feet for reducing noise artifacts within a room.

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

Groundbreaking smartphone app works with Apple iOS® and Android® devices to unleash the full depth, force and nuance of the SB-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.

Connects via Bluetooth for convenient control even when subwoofer is out of sight.
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 room issues.
Stores 3 custom presets for movies, music and other listening experiences such as sports or gaming.
2-way feedback shows updates in real time on both the app and subwoofer interface

 

New Rear Panel Intelligent Control Interface (ICI).

Designed specifically for the 4000 Series Subwoofers, the first ever SVS Intelligent Control Interface (ICI) on the rear panel of the 4000 Series cabinets provide control options for the subwoofer’s most critical functions. Adjustments can be made for volume based on listening preferences and content to achieve full and balanced bass response.

Other features of the ICI include a low pass filter to ensure smooth sonic transitions and seamless blending with loudspeakers and phase control to shift timing of subwoofer output to align with main speakers or additional subwoofers.
