Description

About the SVS SB17-Ultra R|Evolution Subwoofer

The SVS SB17-Ultra R|Evolution Subwoofer uses a massive 17-inch front-firing high-excursion SVS driver, dual 8-inch voice coils, a Sledge STA-2800D dual-mono Class D amplifier, 2,800 watts RMS / 6,000+ watts peak power, and a high-resolution 295MHz Analog Devices DSP. SVS lists the SB17-Ultra R|Evolution with a frequency response of 15Hz to 320Hz, ±3dB, in a sealed cabinet measuring 20.0 inches high, 19.5 inches wide and 21.2 inches deep with grille.

The SB17-Ultra R|Evolution is the sealed model in SVS’s 17-Ultra R|Evolution range.

What We Think

The SVS SB17-Ultra R|Evolution is the kind of subwoofer we look at when a customer wants serious bass without moving to a large ported enclosure.

The sealed cabinet is important. It gives the SB17-Ultra R|Evolution a compact footprint compared with the ported PB17-Ultra R|Evolution, while still delivering huge output and extension down to 15Hz. That makes it a strong option for both home theatre and high-end 2-channel systems where speed, control and musicality matter.

The driver and amplifier platform are also a major step up. The 17-inch driver uses dual 8-inch voice coils and a huge motor assembly, while the STA-2800D amplifier uses dual-mono Class D amplification with MOSFET output stages. SVS says each amplifier drives one of the dual 8-inch voice coils, giving strong control and maximum power delivery.

We also like the tuning flexibility. The SVS app gives control over volume, low-pass filter, phase, polarity, six parametric EQs, room gain compensation, presets and Auto EQ room correction. This is very useful in real NZ lounges and theatre rooms, because the room has a huge effect on subwoofer performance.

For customers wanting a sealed subwoofer that can do both cinematic impact and tight musical bass, the SB17-Ultra R|Evolution is a true reference-level choice.

   SVS lists frequency response at 15Hz to 320Hz, ±3dB.
4. How powerful is the amplifier?
   The Sledge STA-2800D amplifier is rated at 2,800 watts RMS continuous and 6,000+ watts peak dynamic power.
5. What size driver does the SB17-Ultra R|Evolution use?
   It uses a front-firing 17-inch high-excursion SVS driver.
6. What are dual 8-inch voice coils?
   The driver uses two large 8-inch voice coils. SVS uses this design with the dual-mono amplifier to deliver high power, strong control and stable driver behaviour.
7. Does the SB17-Ultra R|Evolution have app control?

Key Features

Flagship Sealed SVS Subwoofer

The SB17-Ultra R|Evolution is the sealed model in SVS’s flagship 17-Ultra R|Evolution range. It is designed for customers who want huge output, deep extension and precise control in a more compact cabinet than a large ported subwoofer.

17-Inch High-Excursion Driver

SVS uses a proprietary 17-inch long-throw front-firing driver. The cone is designed for stiffness, low mass and high output, while the driver platform is built to move serious air with control.

Dual 8-Inch Voice Coils

The SB17-Ultra R|Evolution uses dual 8-inch voice coils. SVS says this design helps transfer power from the dual-mono amplifier outputs to the driver with maximum acoustic output and strong control.

Massive Motor Assembly

SVS lists the woofer at 63.76lb / 28.92kg, with a 54.17lb / 24.57kg motor. This gives the driver the physical foundation needed for very high excursion and reference-level bass output.

2,800W RMS Sledge Amplifier

The Sledge STA-2800D amplifier is rated at 2,800 watts RMS continuous power and 6,000+ watts peak dynamic power. It uses dual-mono discrete Class D amplification with eight 60A / 200V MOSFETs.

295MHz Analog Devices DSP

A high-resolution 295MHz Analog Devices DSP manages the driver, amplifier and subwoofer behaviour. SVS says it provides more than five times the processing power of previous subwoofers, with double-precision 56-bit filtering.

15Hz Bass Extension

SVS lists frequency response at 15Hz to 320Hz, ±3dB. This gives the SB17-Ultra R|Evolution very deep bass extension for movies, music, gaming and large-scale home theatre effects.

Sealed Cabinet Control

The sealed cabinet helps deliver tight, controlled bass. It is well suited to music systems, home theatres and rooms where a more compact cabinet is preferred over a larger ported design.

SVS Auto EQ Room Correction

SVS Auto EQ uses the SVS Subwoofer Control App and a smartphone microphone, or optional external microphone, to analyse the room and optimise the subwoofer output. SVS says it can improve frequency response, tonal accuracy and bass balance across listening positions.

Full SVS App Control

The SVS app gives control over volume, low-pass filter, phase, polarity, six parametric EQs, room gain compensation, tuning modes, power management and memory presets. This makes setup and fine-tuning much easier from the listening seat.

RCA and XLR Connectivity

The amplifier panel includes RCA and balanced XLR stereo input / output connections. SVS lists compatibility with consumer and professional line-level applications.

Power Factor Correction

The amplifier power supply includes active Power Factor Correction and an onboard AC line conditioner. This helps stabilise voltage and maintain performance across a wide range of mains conditions.

Iso-Elastomer Feet

Screw-in Iso-elastomer feet are included to reduce noise artefacts and improve stability. This helps the subwoofer couple more cleanly with the floor.

Premium Finish Options

The SB17-Ultra R|Evolution is available in Piano Gloss Black and Black Oak Real Wood Veneer finishes.

---

+ System Match

A perfect match would be the SVS SB17-Ultra R|Evolution with a high-performance AV receiver, quality speakers and proper room calibration.

For home theatre, use one SB17-Ultra R|Evolution for serious impact, or use two for smoother bass across more seats. Dual subs can help reduce peaks and nulls in a room, giving more consistent bass for the whole listening area.

For 2-channel listening, pair the SB17-Ultra R|Evolution with premium bookshelf or floorstanding speakers. Use the SVS app to tune level, phase, low-pass filter and room gain. This helps the subwoofer blend into the system instead of drawing attention to itself.

For the best result, place the subwoofer carefully, run room correction, then fine-tune using the SVS app.
