Introducing the PB17-Ultra R|Evolution
The ultimate reference standard for low frequency design and performance
Born from three decades of SVS design expertise, the pinnacle of subwoofer performance is here with the PB17-Ultra R|Evolution. Reimagined dual mono-block STA-2800 amplifier technology, first ever 17-in driver with dual 8-in voice coils, and the most powerful DSP ever used in a consumer subwoofer married to advanced power management and auto EQ room calibration. The benchmark for reference subwoofer experiences has arrived.
Breathtaking low frequencies with unerring accuracy, room-shaking output, and stop-on-a-dime control. The deep, chest-thumping slam of cinematic soundtracks and the delicate nuance of musical bass always rendered truthfully.
Whether heard or felt, low frequencies are handled effortlessly without sacrificing sonic fidelity and refinement. With extension to 12 Hz, far below the threshold of human hearing, PB17-Ultra R|Evolution brings sound to life with convincing, visceral, and jaw-dropping impact.
High-Excursion 17-Ultra R|Evolution Driver
17-inch glass fiber composite cone with 55 lb toroidal ferrite magnet motor assembly render massive low frequency output down to 12Hz with pinpoint accuracy and control.
8-inch Dual Voice Coil
Dual voice coil design ensures stable and consistent transfer of motor electro-magnetic energy to the 17-inch cone to maintain precise driver control with maximum efficiency.
Dual Mono Amplifier
Each of the two Class-D mono-block amplifiers with MOSFET output stages drives one of the dual voice coils to double the amount of current being fed to the driver achieving effortless output with lower continuous current demand from a home’s AC circuit.
Switch Mode Power Supply
Time aligns the AC voltage to the AC current while filtering and stabilizing incoming voltage to optimise signal quality and audio performance.
295 MHz Analog Devices DSP
The most advanced processor ever used in a consumer subwoofer optimises every aspect of subwoofer output and usability to maintain flawless performance and intuitive control.
SVS Subwoofer Control Smartphone App
Most convenient way to control all DSP functions, including: volume, 6-band parametric equaliser, low pass filter, phase, polarity, room gain, port tuning, system settings, custom presets, and auto room EQ.
Acoustically Tuned Ported Cabinet Design
Ported cabinet with high airflow 4-inch flared ports, double thick MDF, and rigid internal bracing creates a resonance-free environment for pitch-perfect accuracy free from resonances and coloration.
