SB17-Ultra 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). Effortless Output from High-Excursion 17-inch SVS Driver Lightweight and rigid 17-inch glass fiber composite cone with optimal stiffness-to-mass ratio for maximum efficiency and acoustic linearity 55lb four-piece toroidal ferrite electromagnetic motor generates massive force with precise control, remaining authoritative yet detailed and controlled Extreme-excursion catenary SBR rubber surround maintains pure, long-throw pistonic driver motion Unerring Control from Revolutionary Dual 8-inch Voice Coils 4-layer bi-filar dual voice coils conduct the massive power from the dual-mono amplifier to the motor with maximum thermal efficiency, resulting in effortless acoustic output Copper-clad aluminum voice coil wire combines the best properties of both elements, yielding ideal thermal capacity and magnetic field strength First Ever Dual Mono STA-2800D Amplifier Design with Discrete MOSFET Output Limitless headroom from dual mono-block Class-D amplifiers with MOSFET output stages Each amp drives one of the dual 8-inch voice coils within the motor to assert pinpoint control and maximize power fed to the driver Eight 60 Amp 200 Volt MOSFETs deliver extreme high current for reference-level output with maximum efficiency Performance Enhancing Switch Mode Power Supply Regardless of the power coming out of your household circuit, the SB17-Ultra R|Evolution always maintains peak performance and remains impervious to voltage fluctuations. Onboard AC line conditioner filters and stabilizes incoming voltage, correct waveform distortions, and eliminates electromagnetic and radio interferences to optimize signal quality and audio performance Ensures clean and consistent 160V rail voltage and optimal power delivery from a standard 15-amp home circuit Power-Factor-Correction (PFC) time aligns the AC voltage to the AC current resulting in less heat, greater efficiency, reliable peak power output, and the ability to maintain rated power over a wide range of voltages FEA-optimized convection cooling system has no exterior heatsinks, an extraordinary feat for such a powerful amplifier SPECS ## Features - High-excursion 17” SVS driver with dual 8” voice coil design - SVS Amplifier with Discrete MOSFET Output - 15Hz - 320Hz +/- 3dB - SVS Auto Room Correction with Outboard Microphone - Subwoofer Control Smartphone app with 6 PEQs, custom presets and advanced calibration tools ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DJ1MK22Z | | Additional Features | Hi Res Audio | | Antenna Location | For Surround Sound Systems | | Audio Driver Size | 17 Inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Surround | | Best Sellers Rank | #295,163 in Electronics ( See Top 100 in Electronics ) #466 in Home Audio Subwoofers | | Brand | SVS | | Built-In Media | Microphone, Power Cable | | Color | Black Oak Veneer | | Compatible Devices | Gaming Console, Home Theater, Laptop, Smartphone, Tablet, Television | | Connectivity Protocol | Bluetooth, Wi-Fi | | Connectivity Technology | Bluetooth, Wi-Fi | | Control Method | App | | Customer Reviews | 5.0 out of 5 stars 4 Reviews | | Enclosure Material | Wood | | Frequency Response | 15 Hz | | Is Waterproof | False | | Item Dimensions D x W x H | 20.3"D x 19.5"W x 20"H | | Manufacturer | SVS | | Model Name | SB17-Ultra Evolution Sub Black Oak | | Model Number | SB17-Ultra Evolution Black Oak | | Mounting Type | Floor Standing | | Number of Audio Channels | 5.1 | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 500 Watts | | Speaker Size | 17 Inches | | Speaker Type | Subwoofer | | Specific Uses For Product | Home Theatre | | Subwoofer Diameter | 17 Inches | | UPC | 850029050872 | | Unit Count | 1.0 Count | | Warranty Description | 5 year manufacturer | | Warranty Type | Extended | | Wireless Technology | Bluetooth, Wi-Fi | | Woofer Diameter | 17 Inches | ## Product Details - **Brand:** SVS - **Speaker Maximum Output Power:** 500 Watts - **Frequency Response:** 15 Hz - **Connectivity Technology:** Bluetooth, Wi-Fi - **Audio Output Mode:** Surround ## Images ![SB17-Ultra R|Evolution Subwoofer - Black Oak - Image 1](https://m.media-amazon.com/images/I/81Llj85+ilL.jpg) ![SB17-Ultra R|Evolution Subwoofer - Black Oak - Image 2](https://m.media-amazon.com/images/I/816Jj7ZkL2L.jpg) ![SB17-Ultra R|Evolution Subwoofer - Black Oak - Image 3](https://m.media-amazon.com/images/I/81zi2+Y4U4L.jpg) ![SB17-Ultra R|Evolution Subwoofer - Black Oak - Image 4](https://m.media-amazon.com/images/I/71pw22+SJhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***R on April 29, 2025* ### ⭐⭐⭐⭐⭐ Review *by A***R on July 15, 2025* ### ⭐⭐⭐⭐⭐ Review *by B***H on April 5, 2026* ## Frequently Bought Together - SVS SB17-Ultra R|Evolution 17" Sealed Subwoofer (Oak Black) - SVS SoundPath Subwoofer Isolation System, 4-Pack - FosPower Banana Plugs 6 Pairs / 12 pcs, Closed Screw 24K Gold Plated Banana Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/663624550-sb17-ultra-r-evolution-subwoofer-black-oak](https://www.desertcart.ro/products/663624550-sb17-ultra-r-evolution-subwoofer-black-oak) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-09*
