SVS PB17-Ultra R|Evolution Subwoofer

Built for reference-level home theater and serious 2-channel listening, the SVS PB17-Ultra R|Evolution is a flagship ported subwoofer engineered to deliver extreme low-frequency output with precision control. A front-firing 17-inch high-excursion driver with unprecedented dual 8-inch voice coils pairs with the Sledge STA-2800D dual-mono amplifier platform to produce chest-thumping impact, effortless headroom, and detailed bass texture—without sacrificing accuracy. With multiple tuning modes, deep extension down to 12Hz (extended mode), and full control from the SVS Subwoofer smartphone app (with Auto Room EQ coming soon via over-the-air update), it’s designed to dominate large rooms while staying refined enough for audiophile-grade musical bass. The PB17 Ultra is part of ListenUp's SVS Ported Subwoofer Collection.

What It's Good At:

• Delivering room-pressurizing, ultra-deep bass down to 12Hz (extended mode) for movies and immersive gaming
• Producing clean, high-output slam with massive headroom for large rooms and reference listening levels
• Fine-tuning performance with multiple ported/“sealed” tuning modes and app-based DSP controls
• Blending smoothly with any system via adjustable filtering, phase, polarity, PEQ, and room gain features
• Supporting flexible integration using RCA or balanced XLR I/O, plus trigger and IR control options
• Making setup and daily adjustments easy with app control, presets, and a rear-panel OLED interface

How low does the PB17-Ultra R|Evolution play?

It reaches down to 12Hz in extended mode (±3 dB), delivering the kind of ultra-deep bass you feel as much as you hear. Standard mode is rated 14–220Hz (±3 dB).

What’s the difference between Standard, Extended, and Sealed tuning modes?

Standard mode uses all ports open for maximum output, Extended mode uses one port plugged (two open) for deeper extension, and Sealed mode plugs all ports for tighter transient response and higher upper-bass extension.

Can I control it from my phone?

Yes. The SVS Subwoofer Control app works with iOS, Android, and Amazon Fire devices and provides access to volume, filtering, phase, polarity, PEQ, room gain compensation, tuning modes, presets, and more.

Is Auto Room EQ included?

Auto Room Equalization is planned to arrive via an over-the-air app update (coming soon). It uses your device’s microphone to measure your room and apply corrective EQ filters.

What connections does it support (RCA/XLR)?

It supports both unbalanced RCA and balanced XLR line-level inputs and outputs, including LFE use. This makes it compatible with consumer AVRs as well as balanced preamps and processors.

Does it work with dual subwoofer setups?

Absolutely. Multiple subs can improve seat-to-seat consistency, increase headroom, and reduce localization; the PB17 includes outputs suitable for daisy-chaining depending on your system approach.

How big and heavy is it?

It measures 25.0" H x 21.7" W x 29.3" D with the grille installed and weighs 164.7 lb unboxed. Planning the path into the room (and using help) is strongly recommended.

Does it support trigger and IR control?

Yes. It includes a 3.5mm trigger input (3–12V AC/DC) and a 3.5mm IR input for integration with control systems, plus app-based power options.
