SVS PB17-Ultra R|Evolution Lacquered Black

SVS PB17-Ultra R|Evolution: power, precision and control

The SVS PB17-Ultra R|Evolution is equipped with a 17-inch bass driver, the largest ever used by SVS. This driver is designed to handle high power levels, thanks to a dual 8-inch voice coil that maintains a stable transfer of electromagnetic current from the subwoofer amplifier to the 55-pound toroidal ferrite magnet motor. The voice coil is made from copper-clad aluminum wire to optimize thermal capacity and magnetic field strength.

The 17-inch driver is made up of a fiberglass composite cone, a long-throw catenary rubber surround, and a toroidal ferrite electromagnetic motor. This combination delivers deep bass reproduction, with the ported PB17-Ultra model reaching frequencies as low as 12 Hz. These specifications are engineered to provide accurate frequency response and maintain acoustic linearity.

The most powerful amplification ever used in a consumer subwoofer

The STA-2800D Class D dual mono-block amplification with discrete MOSFET output stage is the sonic muscle behind this SVS subwoofer amplifier, the most powerful and faithful ever developed by the brand. Each amplifier drives one of the voice coils for precise control and maximum power. Eight 60A 200V MOSFETs deliver extremely high current for reference-level output with maximum efficiency.

A high-performance switch-mode power supply

No matter what power is supplied by the electrical circuit, the PB17-Ultra R|Evolution always maintains optimal performance and remains insensitive to voltage fluctuations. A built-in AC line conditioner filters and stabilizes the input voltage, corrects waveform distortion and eliminates electromagnetic and radio interference to optimize signal quality. Power factor correction (PFC) synchronizes AC voltage and current, reducing heat, improving efficiency, and allowing the rated power to be maintained over a wide voltage range.

An ultra-sophisticated 295 MHz Analog Devices DSP

Orchestrating this cutting-edge ecosystem of amplifier, motor and driver is the most sophisticated DSP ever used in a consumer subwoofer. It precisely shapes in-room frequency response, stabilizes the AC power supply and continuously monitors temperature, voltage and current to ensure maximum efficiency and output power. Advanced digital audio processing and DACs with a 120 dB signal-to-noise ratio deliver greater headroom, lower noise and flawless fidelity.

Smartphone control app, now with automatic room correction

Compatible with iOS, Android and Fire, the SVS app allows convenient setup and management of the subwoofer via comprehensive controls (volume, low-pass filter, phase, parametric EQs, port tuning modes, power management, etc.). Three savable presets allow the system to be quickly adapted to listening preferences.

The new automatic room correction function uses the smartphone’s microphone and the SVS app to measure the subwoofer’s acoustic performance in the room and automatically calculate EQ filters that optimize frequency response at the listening position. A simple multi-step process for significant improvements. Available soon via an over-the-air update.

Extended, linear frequency response

• 14 Hz to 220 Hz +/- 3 dB (standard mode – all ports open)
• 12 Hz to 220 Hz +/- 3 dB (extended mode – 2 ports open)
• 14 Hz to 320 Hz +/- 3 dB (sealed mode – all ports closed)

The roll-off slope is specifically optimized to make the most of available room gain. Measurements at 2 meters in free field away from reflective structures (quasi-anechoic).

Premium design down to the smallest details

Available in Piano Gloss Black and real wood veneer Black Oak finishes, the PB17-Ultra R|Evolution features an extra-thick ABS protective grille and a fabric mesh frame that protect the driver. The OLED amplifier rear panel allows quick, direct control of the most important functions.

The robust MDF cabinet with internal bracing ensures resonance-free performance even at the highest power levels. Screw-in iso-elastomer feet reduce sonic artifacts and improve stability. With its triple 4-inch ports and generous dimensions (W 635 x D 744 x H 550 mm), this 74.7 kg subwoofer will integrate perfectly into your system.

What are the main advantages of the SVS PB17-Ultra R|Evolution subwoofer?
