The SVS SB-4000 Subwoofer stands out as a powerhouse in the realm of home audio systems, engineered to deliver deep, impactful bass that enhances any listening experience, from movies to music. Designed with precision and equipped with advanced technology, the SB-4000 is an ideal choice for audiophiles seeking a superior subwoofer that combines power with nuanced sound reproduction.
At the heart of the SVS SB-4000 is the Sledge STA-1200D amplifier, renowned for its impressive power output. With a rating of 1,200 watts RMS and over 4,000 watts peak power, this amplifier ensures that the subwoofer can handle even the most demanding audio tracks with ease. The Class D design of the amplifier, combined with fully discrete MOSFET outputs, allows for efficient power usage and precise control, ensuring consistent performance at all volume levels.
The SB-4000 features a high-excursion SVS driver designed to move large volumes of air while maintaining control and accuracy. The driver is supported by a dual ferrite magnet motor assembly, weighing nearly 40 pounds, which generates significant magnetic force for deep bass production. The edge-wound voice coil, crafted from eight layers of aluminum flat wire, minimizes distortion and enhances heat dissipation, contributing to the subwoofer’s ability to deliver clean, distortion-free bass.
A key component of the SB-4000’s performance is its sophisticated digital signal processing (DSP) engine. The Analog Devices DSP engine provides precise audio rendering, ensuring that every note and beat is reproduced accurately. The DSP engine also offers advanced in-room tuning capabilities, optimized frequency response curves, and powerful control features.
One notable feature is the 3-band parametric EQ, which allows users to fine-tune the subwoofer’s output to match their room’s acoustics. This level of customization helps to eliminate peaks, nulls, and other room-related audio issues, resulting in a more balanced and immersive listening experience.
The EQ settings, along with other adjustments such as volume, low pass filter, phase, and polarity, can be controlled via the SVS Subwoofer Smartphone App, which connects to the subwoofer through built-in Bluetooth.
The SB-4000 is designed for versatile connectivity, featuring both XLR and RCA stereo input/output options. This makes it compatible with a wide range of audio systems and allows for seamless integration into existing home theater setups. The adjustable low-pass filter further aids in achieving a cohesive audio experience, ensuring that the subwoofer blends well with the main speakers.
Constructed with a double thick 2-inch MDF front baffle and rigid internal bracing, the SB-4000 is built to minimize unwanted resonance and coloration. The acoustically inert design of the sealed box cabinet contributes to the subwoofer’s ability to produce tight, musical bass, which is particularly beneficial for music listening.
The exterior of the SB-4000 is both functional and aesthetically pleasing, available in Premium Black Ash or Piano Gloss Black finishes. The subwoofer includes a non-resonant steel mesh grille and elastomer feet, which help reduce noise artifacts within the room. These design elements ensure that the SB-4000 not only performs well but also complements the visual style of high-end home theaters.
The performance of the SB-4000 is characterized by its ability to produce exceptionally low and accurate bass. With a frequency response that extends down to 19Hz, the subwoofer is capable of delivering the deep, visceral bass that enhances movie soundtracks and music.
Despite its powerful capabilities, the SB-4000 maintains a relatively compact footprint, with dimensions of 18.3 inches (H) x 17.8 inches (W) x 18.6 inches (D) and a weight of 102.3 pounds.
The SVS Dual SB-4000 Subwoofers are available for purchase at Dreamedia for $3,599.98, where you can also explore other SVS products.
