Features

Dual 9" High Output Woofers: Each SVS 3000 In-Wall Subwoofer features dual 9" aluminum cone woofers that are both rigid and yet lightweight with an all-new oversized motor design in a custom-tooled basket that have been optimized for maximum acoustic output and thermal efficiency. The oversized, vented motor structure is optimized for efficient thermal and mechanical-energy management in a confined space. Massive electromagnetic force produced by the motor, in symphony with the high current driving power of the Sledge amplifier, allows the 3000 In-Wall to maximize on the output potential of the dual 9" aluminum cone woofers.

Acoustically Inert Sealed Cabinet: Each SVS 3000 In-Wall Subwoofer employs an acoustically inert sealed cabinet cabinet for tight, accurate bass in the wall. Aircraft grade aluminum panels were custom formed into rigid 2.5mm thick front and rear baffles around an MDF frame of the in-wall subwoofer enclosure to create an unyielding, sonically inert cabinet for the drivers. Extensive front to back bracing eliminates any potential cabinet resonances even at extreme playback levels. The included detachable magnetic grille is acoustically transparent and paintable for seamless blending into any home environment.

Sledge ST-A800D2C Amplifier: The Sledge STA-800D2C amplifier maximizes the full potential of the dual 9" woofers with effortless power and absolute control. The innovative design combines the efficiency of a Class D amplifier with the ability to move large amounts of current through the fully discrete MOSFETs, enabling immense output with exceptional precision resulting in outstanding real-world subwoofer performance at all volume levels. The Sledge ST-A800D2 amplifier utilizes a sophisticated 50Mhz High Resolution Analog Devices Audio DSP that is one of the most advanced digital processors ever used in a subwoofer. Its the "brains" behind the serious brawn of the Class D amplifier that maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning, optimized frequency response curves, powerful DSP controls and more.

Line-Level Inputs & Outputs: The Sledge ST-A800D2C is equipped with a set of line-level RCA inputs that can be utilized as a stereo RCA input, as well as a LFE (low frequency effect) input. There is also a stereo RCA line-level output. For a single mono connection to a home theater receiver, use the amplifier's R/LFE input. For stereo receivers, use both the L/R stereo RCA inputs. Use the Left/Right stereo RCA outputs on the ST-A800D2C to daisy-chain additional subwoofer amplifiers

Speaker Terminals: Each 3000 In-Wall Subwoofer is fitted with banana plug inserts and comes with a set of banana plugs to attach your in-wall speaker wire. The Sledge STA-800D2C amplifier is outfitted with two sets of binding post speaker terminals that will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana plugs (single or dual). The two sets of binding posts output terminals allow for connection of the two included in-wall subwoofers, delivering 400 watts (RMS) to each in-wall subwooer enclosure.

Front-Panel Controls & Display: The Sledge ST-A800D2C features a front-panel display with push-button controls. The front-panel display indicates volume level, low pass filter frequency, and phase setting. The push-button controls operate volume level, low pass crossover filter frequency, and phase setting. The main power on/off switch is also located on the front-panel of the amplifier.

SVS Subwoofer App: The SVS Subwoofer app (for Apple iOS and Android OS) is the most convenient way ever to control volume, access multiple DSP functions and program custom presets for one-touch tuning optimized for music, movies, gaming, and more from your Bluetooth-connected Apple iOS or Android mobile device. Adjust crossover frequencies, a three-band parametric EQ, polarity, room gain and more from your favorite seat. The SVS subwoofer app also allows advanced customization so you can name the subwoofer for easy preset switching, choose the subwoofer standby mode and reset the subwoofer to factory settings. Bluetooth connectivity allows full control, even when the subwoofer is out of sight and bi-directional feedback shows adjustments in real-time on both the app and rear-panel subwoofer interface.

• Volume Level: The Volume Level (-60 to 0dB) affects how loud the subwoofer plays. It should be adjusted to match the output level of your loudspeakers. Setting the level too high will cause the bass to seem bloated and is the single most common cause of bad sounding subwoofers. Setting it too low will cause your movie or music soundtracks to sound "thin" and less dynamic.
• Low Pass Crossover: This Low Pass Crossover affects the upper frequency limit of the powered sub. The control range is 30-200Hz, along with a "LFE" (disabled) setting. The slope of the low pass crossover can be set 6, 12, 18, or 24dB/octave. For connection to a home theater receiver, the low pass should be set to "LFE" (disabled). For stereo receiver, it should be adjusted to blend with the natural roll-off frequency of your loudspeakers.
• Phase Adjustment: The Phase Adjustment (0-180°) solves sound wave cancellation issues at specific frequencies and perfectly aligns the arrival of output from speakers and subwoofers to your listening position. Normally set to 0° if the subwoofer is near the main speakers. Adjusting Phase shifts timing of the subwoofer output to align with the main speakers or additional subwoofers.
• Polarity Switch: In some cases, reversing polarity (Positive or Negative) solves dips or humps at the crossover frequency between a subwoofer and speaker and can be used to fix bass nulls or overly boomy spots in the listening area. Reversing the electrical polarity of the subwoofer amplifier makes it so the woofer moves in when speaker drivers move out and is normally set to positive.
• Parametric EQ: The built-in Parametric EQ is a powerful tool for removing peaks and dips in your listening area, and for creating custom subwoofer output based on personal listening preferences. It allows you to set the desired center frequency of the filter (20-200Hz), increase or decrease the SPL dB of the filter (-12 to 6.0dB), or adjust the bandwidth of the filter (0.2-10.0).
• Room Gain Compensation: The Room Gain Compensation feature fixes bloated sounding bass by optimizing low frequency output and extension when too much sound wave density is being created by a small room. The RGC frequency can be set to 25, 31, or 40Hz; while the RGC slope can be set to 6 or 12dB.
• Presets: You can store up to three preset settings for movie, music and custom. This enables easy switching to optimize the SB-3000's output and settings based on your specific listening preferences with different kinds of content. If using the SVS App, these presets can be renamed as desired.

In-Wall Installation: Each 3000 In-Wall Subwoofer requires a rectangular cutout in the wall and is secured in place by the way of a "dog-leg" mounting system. A mounting template is included, while a pre-construction kit is sold separately. The "dog-leg" clamp system will accommodate 0.25" to 2.0" drywall thickness. Make sure to leave at least 0.75" of space around the interior of the cutout to accommodate the "dog-leg" clamps. The in-wall subwoofers can be mounted vertically or horizontally.
