SVS Subwoofers PB17 Ultra 17" Ported Subwoofer
A quantum leap forward in design and performance with multiple groundbreaking innovations - the most formidable and sophisticated ported subwoofer ever developed.
All-new 17-inch driver with first-ever dual 8-inch voice coils. The most powerful amplifier ever deployed in a consumer subwoofer with unprecedented dual mono-block design married to the extreme intelligence of a 295MHz DSP. All managed by the most sophisticated subwoofer control app, now with auto EQ room correction (available soon via over-the-air update).
Born from three decades of SVS design expertise, PB17-Ultra R|Evolution is the pinnacle or ported subwoofer performance. A massive 17-inch driver with first ever dual 8-in voice coils driven by the most powerful amplifier ever deployed in a consumer subwoofer with DSP intelligence far beyond anything available. All married to advanced power management and auto EQ room correction. 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 torodial ferrite magnet motor assembly renders massive low frequency output down to 13Hz with pinpoint accuracy and control.
8-inch Dual Voice Coils
Dual voice coil design ensures stable and consistent transfer of motor elctro-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 stabilising incoming voltage to optimise signal quality and audio performance.
295 MHz Analogue 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.
Triple Ported Acoustically Tuned Cabinet Design
Three 4-inch ports optimise airflow while rigid internal bracing creates a resonance-free environment for uncompromised subwoofer performance.
