SVS SB17-Ultra R|Evolution Sealed Box Subwoofer

Unleashing the Power of the SVS SB17-Ultra R|Evolution Sealed Box Subwoofer

When it comes to redefining low-frequency audio performance, the SVS SB17-Ultra R|Evolution sets a new benchmark. This sealed box subwoofer combines cutting-edge technology, precision engineering, and an elegant design to deliver breathtaking bass that is both powerful and refined. Let’s dive into what makes this subwoofer a standout choice for audiophiles and home theatre enthusiasts in Australia.

A Revolutionary 17-Inch Driver for Unmatched Bass Performance

At the heart of the SB17-Ultra R|Evolution is its 17-inch glass fibre composite cone, engineered with an optimal stiffness-to-mass ratio. This ensures maximum efficiency and acoustic linearity, producing deep, chest-thumping bass down to an astonishing 15 Hz, well below the threshold of human hearing. The driver features:

• A 55 kg (121 lb) toroidal ferrite motor assembly that generates immense force while maintaining precise control.
• An extreme-excursion catenary SBR rubber surround for long-throw pistonic motion without distortion.

This combination allows the subwoofer to deliver massive sound pressure levels with pinpoint accuracy, making it perfect for both cinematic explosions and delicate musical nuances.

Dual 8-Inch Voice Coils: Precision Meets Power

The SB17-Ultra R|Evolution introduces a groundbreaking dual 8-inch voice coil design, ensuring stable electromagnetic energy transfer to the driver. Key features include:

• 4-layer bi-filar dual voice coils for maximum thermal efficiency.
• Copper-clad aluminium wire construction, combining high thermal capacity with strong magnetic field strength.

This innovative design ensures effortless output while maintaining precise control over every note.

Dual Mono STA-2800D Amplifier: Limitless Headroom

Powering this beast is the first-ever dual mono-block Class-D amplifier system with discrete MOSFET output stages. Each amplifier drives one of the dual voice coils, doubling the current fed to the driver while maintaining efficiency. Highlights include:

• A total power output of up to 2,800 watts RMS.
• Eight 60 Amp/200 Volt MOSFETs delivering reference-level output.
• A switch-mode power supply with Power-Factor-Correction (PFC) technology that aligns AC voltage and current for consistent performance on standard Australian 240V circuits.

This ensures clean and reliable power delivery even during demanding audio playback sessions.

Advanced DSP Technology for Flawless Audio Reproduction

The SB17-Ultra R|Evolution employs a state-of-the-art 295 MHz Analog Devices DSP, offering unparalleled control over its performance. Features include:

• Real-time monitoring of thermal conditions, voltage stability, and current flow.
• Advanced digital audio processing with a signal-to-noise ratio of 120 dB for pristine fidelity.
• Auto EQ room correction via the SVS Subwoofer Control App, which optimises in-room frequency response using your smartphone or external microphone.

With these capabilities, you can enjoy perfectly tuned bass tailored to your listening environment.

SVS Smartphone App: Intuitive Control at Your Fingertips

The SVS Subwoofer Control App provides seamless access to all DSP functions from your smartphone or tablet. Compatible with iOS, Android, and Amazon Fire devices, it allows you to adjust:

• Volume levels
• Low-pass filter settings
• Phase alignment
• Room gain compensation
• Six-band parametric equalisers

Additionally, you can save custom presets for different listening modes such as movies or music. The app also supports future firmware updates via over-the-air downloads.

Sealed Cabinet Design: Built for Acoustic Perfection

The SB17-Ultra R|Evolution’s cabinet is crafted from double-thick MDF with rigid internal bracing to eliminate unwanted resonances. Its sealed design enhances pitch-perfect accuracy while maintaining compact dimensions suitable for Australian living spaces. This ensures that every note is delivered without coloration or distortion.
