SVS 3000 In-Wall Dual Subwoofer System with Sledge STA-800D2C Amplifier

The SVS 3000 In-Wall Dual Subwoofer System delivers massive, room-filling bass without occupying valuable floor space. Designed for premium home theaters and high-performance music systems, this dual-subwoofer configuration combines two sealed in-wall subwoofer enclosures with a powerful external Sledge STA-800D2C amplifier for deep, accurate and impactful low-frequency performance.

Each in-wall enclosure features two custom-designed 9-inch high-excursion active drivers, providing four active drivers across the complete dual-subwoofer system. The included amplifier delivers 800 watts RMS and over 2,500 watts peak power, distributing 400 watts RMS to each subwoofer enclosure when both are connected.

With frequency response extending from 22Hz to 250Hz (+/-3dB), in-room low-frequency extension to approximately 19Hz and combined maximum output of 110.6dB at 32Hz under specified measurement conditions, the SVS 3000 In-Wall Dual System delivers powerful cinematic bass with precise control and musical accuracy.

Massive Cinematic Bass Without Floor Space

The SVS 3000 In-Wall subwoofer was engineered to deliver the performance of a powerful freestanding subwoofer from an enclosure that installs discreetly between standard wall studs. Its shallow, sealed cabinet is suitable for existing rooms and new construction, allowing a high-performance bass system to blend seamlessly into the room.

The dual-subwoofer configuration provides greater flexibility for distributing bass throughout larger listening spaces, helping achieve more consistent low-frequency performance across multiple seating positions.

Four High-Excursion 9-Inch Active Drivers

Each subwoofer enclosure houses two proprietary 9-inch active drivers engineered for maximum linear excursion and output from a shallow cabinet. Across the complete system, four drivers combine to produce powerful, controlled bass for demanding movie soundtracks and music.

Rigid, lightweight aluminum cones with aluminum dustcaps provide excellent transient response, while proprietary long-throw surrounds and precisely tuned ferrite motor assemblies maintain control during demanding low-frequency passages.

Each driver features a high-current four-layer copper voice coil, an optimized motor assembly and advanced suspension components designed to minimize distortion, power compression and unwanted mechanical vibration.

Sledge STA-800D2C Amplifier

The included SVS Sledge STA-800D2C amplifier combines high-efficiency Class D amplification with fully discrete MOSFET output technology. Rated at 800 watts RMS and over 2,500 watts peak power, it provides the current and control required to drive the dual in-wall subwoofer system.

When connected to two subwoofer enclosures, the amplifier distributes its 800 watts RMS output evenly, providing 400 watts RMS per enclosure. Its compact 2U rack-mount design allows the amplifier to be installed with other home theater electronics, keeping the subwoofer installation clean and discreet.

Advanced 50MHz DSP Processing

A high-resolution 50MHz Analog Devices Audio DSP with double-precision 56-bit filtering provides sophisticated bass management and precise control over the subwoofer system.

Adjustable low-pass filtering, phase, polarity, room gain compensation and three-band parametric equalization allow the system to be optimized for different rooms, speakers and listening preferences.

SVS Subwoofer Control Smartphone App

The SVS Subwoofer Control App provides convenient wireless adjustment of the amplifier's DSP settings from compatible iOS, Android and Amazon devices. Bluetooth connectivity allows users to fine-tune bass performance from their listening position without accessing the amplifier directly.

Three customizable presets can be saved for different listening applications, including movies, music and gaming. The app also provides adjustment of volume, crossover frequency, parametric EQ, polarity, phase and room gain compensation.

Acoustically Inert Sealed Cabinet Construction

Each sealed enclosure features rigid 2.5mm aircraft-grade aluminum front and rear baffles surrounding a reinforced MDF frame. Extensive internal bracing helps prevent cabinet resonance and unwanted coloration, allowing the drivers to deliver clean, controlled low-frequency output.

Paintable, magnetically attached steel mesh grilles provide a discreet appearance that can be matched to the surrounding wall finish.

Flexible Installation for New and Existing Rooms

The SVS 3000 In-Wall system is designed for installation within standard 16-inch stud spacing. Dog-leg mounting and direct-to-stud attachment options provide installation flexibility, while dedicated speaker cable connections with banana terminals simplify wiring between the amplifier and subwoofer enclosures.

An optional pre-construction bracket is available separately for installations planned during construction or renovation.
