- Three convenient custom presets allow for perfect tuning in any room or system, from your favorite seat.
- Single tap adjustment for controlling variable port tuning with standard, extended and sealed modes.
- Easy-to-follow tutorial provides clear guidance for all functions.
SVS Subwoofer Smartphone App Features:
Adjust to make your system’s low end more robust and extended while remaining accurate. The subwoofer should sound like it’s naturally adding bass for all the speakers without overly drawing attention to itself. Different content has different levels of output so it’s normal to adjust volume based on source material and your personal listening preferences.
Low Pass Filter
Enables smooth sonic transition and flat frequency response between speakers and the subwoofer. If using an AV Receiver with a Subwoofer Output, leave in the OFF position. For two-channel systems using an AV processor or preamp, this allows you to control the upper frequency cut-off to blend with main speakers. It also allows you to adjust slope, or the rate at which the low pass filter rolls off.
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.
In some cases, reversing polarity 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
Powerful tool for removing peaks and dips in your listening area, and for creating custom subwoofer output based on listening preferences. Works best when used with acoustic measurements.
Allows you to set the desired center frequency of the filter, increase or decrease the SPL dB of the filter or adjust the bandwidth of the filter.
Room Gain Compensation
Fixes bloated sounding bass by optimizing low frequency output and extension when too much sound wave density is being created by a small room.
Allows custom tuning for different listening preferences. Exchanges max output for low frequency extension and transient speed.
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.
Allows up to three pre-saved settings for movie, music and custom. This enables easy switching to optimize your 13-Ultra subwoofer’s output and settings based on your specific listening preferences with different kinds of content.
Allows you to make further customizations and reset your subwoofer to factory settings.
Sledge STA-1200D Amplifier – Massive Output, Sophisticated DSP, Advanced Power Management
Rated conservatively at 1,200 watts RMS, and 4,000+ watts peak power, the Sledge STA-1200D amplifier uses an efficient Class D design combined with fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other powered subwoofer manufacturer.
1,200 Watts RMS, 4,000+ Watts Peak Power with Discrete MOSFET Output
Conservatively rated at 1,200 watts RMS, 4,000+ watts peak power, the SVS Sledge STA-1200D Amplifier combines the efficiency of a Class D amplifier with the ability to move nearly limitless amounts of current through the fully discrete MOSFETs. The result, massive and effortless power with pinpoint control and accuracy at all drive levels.
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.
