SVS, a manufacturer of high-performance speakers, subwoofers, and accessories, has just announced a new flagship subwoofer series, 17-Ultra R|Evolution. A complete reimagining of subwoofer design for the Ohio-based audio brand making it the most powerful, sophisticated, and advanced SVS subwoofers ever introduced the company proclaims.

Starting with the driver the Midwest-based company points out, the development of the R|Evolution subwoofer was a ground-up process engineering starting with the largest driver ever deployed in an SVS subwoofer the company underscores. To ensure stable transfer of electro-magnetic current from the dual mono-amplifier to the 55-pound toroidal ferrite magnet motor, SVS designed a dual eight-inch voice coil resulting in effortless output and control over the 17-inch driver. SVS notes the driver’s copper-clad aluminum voice coil wire combines the best properties of both elements, yielding high levels of thermal capacity and magnetic field strength in the motor.

“SVS is a restless company. We are never satisfied with making modest improvements just for the sake of launching a new product,” says Gary Yacoubian, president, SVS.

“That restlessness is what fueled the top to bottom advancements of our flagship 17-Ultra R|Evolution subwoofers. Literally every part of the ecosystem was reimagined to achieve an unprecedented level of low frequency performance and world class user experience. They truly represent a quantum leap forward in subwoofer design and I could not be prouder of what our team accomplished.”

R|Evolution Subwoofer Utilizes Latest SVS R&D Concepts

Elaborating on design of its new R|Evolution subwoofer, the product employs an all new high-excursion 17-inch driver that features a glass-fiber composite cone, long-throw catenary SBR rubber surround, and toroidal ferrite electromagnetic motor that rounds out the driver design. This combination SVS comments, generates massive sound pressure levels well below the threshold of human hearing (15Hz for SB17-Ultra and 12Hz for PB17-Ultra) with frequency response accuracy and acoustic linearity.

The Future of Digital Lighting & Control

As a custom integrator, lighting is in demand. Effective communication, education and showcasing the value proposition of LED light fixtures in conjunction with integrative control systems are the keys to overcoming challenges and closing sales in this specialized market.

Generating the sonic muscle behind the most powerful and SVS subwoofers emphasizes is a ever is a 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.

Given the amplifier’s output potential, SVS says that its designers needed an equally capable power supply to accommodate the limits of a typical 15-amp home AC circuit. The 17-Ultra R|Evolution subwoofers have an answer for this too SVS boasts—an onboard AC line conditioner with power factor correction that is said to stabilize the incoming voltage.

These design elements are engineered to correct waveform distortions, while eliminating electromagnetic and radio interference. By doing so, SVS stresses, the power conditioning continuously optimizes signal quality while ensuring the subwoofers remain stable to voltage fluctuations.

The company also suggests that while DSP (digital signal processing) remains absent from many subwoofers in the market, SVS states that it 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 SVS’ comprehensive subwoofer control smartphone app: the SVS app. This interface solution 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 integrators to setup for fast and easy system adjustments to match their clients’ listening preferences.

In addition, the 17-Ultra R|Evolution subwoofers also offer integrators an intuitive Auto EQ Subwoofer Room Correction platform. SVS says that dealers can use the SVS app and the built-in microphone on a smartphone to automatically apply equalization filters, while capitalizing on available room gain, and optimizing in-room frequency response at main listening positions for improved in-room performance. SVS says the simple auto calibration process requires just a few steps to resolve all the acoustic issues caused by residential small-room dimensions.

The Auto EQ Subwoofer Room Correction will be available via an over-the-air app and firmware update coming soon.
