The new flagship subwoofers from SVS

They may look very similar to the outgoing models, but the new 17-Ultra R|Evolution series has had nearly every molecule changed and upgraded to the latest tech SVS has to offer.

Starting with an all new high-excursion 17-inch driver featuring a glass-fiber composite cone, long-throw catenary SBR rubber surround, and toroidal ferrite electromagnetic motor allow these two subs to generate massive sound pressure levels well below the threshold of human hearing. (15Hz for SB17-Ultra and 12Hz for PB17-Ultra)

Generating the sonic muscle behind the most powerful and highest fidelity SVS subwoofers ever is a unique dual mono-block STA-2800D Class-D amplifier with MOSFET output stage. Each amplifier drives one of the dual voice coils to increase the power into the motor while asserting pinpoint control and maximizing output potential. Eight 60 Amp 200 Volt MOSFETs deliver extreme high current for reference-level output with maximum efficiency.

SVS integrated the most sophisticated DSP ever to optimize all aspects of performance and usability. The 295MHz Analog Devices DSP orchestrates every function of the amplifier to shape in-room response and stabilize AC voltage delivery while managing a multi-point thermal and current monitoring system for optimal performance and efficiency. In addition, advanced digital audio processing and DACs (Digital-to-Analog Converters) with 120 dB Signal-to-Noise Ratio provide greater headroom, lower noise, and pristine fidelity.

Calibration of the 17-Ultra R|Evolution series is managed via the most comprehensive subwoofer control smartphone app available. The SVS app features controls for volume, low pass filter, phase, polarity, six parametric equalizers, room gain compensation, port tuning (PB17-Ultra R|Evolution only), power management settings, and more. There are also three convenient memory presets for fast and easy system adjustments to match your listening preferences.

Also new to the 17-Ultra R|Evolution subwoofers is the intuitive Auto EQ Subwoofer Room Correction. Using the SVS app and the built-in microphone on a user’s smartphone, the feature applies equalization filters, capitalizes on available room gain, and optimizes in-room frequency response at main listening positions for optimal in-room performance. The simple process requires just a few steps and achieves pristine fidelity by resolving all the acoustic issues caused by your room in a few easy steps. Auto EQ Subwoofer Room Correction will be available via an over-the-air app and firmware update coming soon.

Both models are now shipping in the US.
