    Well, there was bad weather in Ohio last month so I unplugged my SVS SB13-Ultra. After the rain ended, I plugged it back in and heard a pssst type metallic sound. That was the end. I tried the spare fuse with no luck. Both fuses are fine. So, I bought another plate amp from SVS and off I went with a lighter wallet. Im now selling this as not working. I figure its probably an easy fix for an engineer or electrician. It will be well packaged. General information about my listingsYou will receive the item(s) displayed in the photo gallery above.

    A perfect 17-inch square, the SB13-Ultra subwoofer’s compact design is ideally suited for spaces where larger subwoofers wouldn’t fit, but deep, palpable bass is still desired. Painstakingly engineered, the SB13-Ultra is loaded with advanced design elements that set it apart from the competition.High Output SVS Ultra Series Driver DesignInstead of merely adapting the previous Ultra driver to a more compact sealed enclosure, SVS engineers radically revised the motor geometry, added a unique, ultra-high-power aluminum voice coil, and developed a custom gap extension plate that increases linear stroke and reduces distortion. Add to that dual linear-roll spiders, a stitched parabolic surround, and the ultra-light but rigid Rohacell composite cone material of the 13-Ultra driver, and the result is an incredibly robust subwoofer with extreme excursion that easily outperforms subwoofers costing twice as much.Powerful and Sophisticated Sledge STA-1000D AmplifierTo complement these driver refinements, the SB13-Ultra employs an integrated 1,000 watts RMS, 3,200+ watts peak power DSP Sledge amplifier with sophisticated DSPs perfectly matched to the driver and cabinet, and an equalization curve optimized for enhanced transient response and to complement room gain. Although it’s rated to deliver 20Hz to 460Hz (±3dB), in the right room, with the right settings, it can easily reach down to a gut-wrenching 15Hz, without diminishing the nuanced textures and incredible transient response that audiophiles demand of music. Its room gain compensation control also allows the SB13-Ultra to sonically adapt for optimal in-room frequency response. Power users will appreciate the two-band parametric equalizer (PEQ), yet this advanced feature is easily disabled for users who prefer to rely on the bass management of their favorite preamp or receiver.Acoustically Inert, Rigidly Braced CabinetAcoustically Inert, Rigidly Braced CabinetAcoustically Inert, Rigidly Braced CabinetThe SB13-Ultra subwoofer cabinet is rigidly braced and acoustically inert for uncompromising performance and its understated but elegant design allow it to blend with any room’s décor, while still delivering thunderous low frequency impact that’s impossible to ignore.Described in reviews as authoritative, stunning, immensely powerful, pitch-perfect, versatile, and jaw-droppingly accurate, words and accolades only tell part of the story. The feeling you get when a musical bassline drops or your home theater erupts to life during an action movie sequence, or the shivers that goes down your spine when it resolves a deep but delicate sonic detail; these are the moments when the SB13-Ultra subwoofer shows its ultimate value.

    SVS SB13-Ultra High-End Subwoofer in neuwertigem Zustand, inkl. Soundpath-Füßen!Verkauft wird ein SVS SB13-Ultra in matt schwarz. Der geschlossene Subwoofer gehört zu den leistungsstärksten Modellen von SVS und ist der Vorgänger des SVS SB4000. Er verfügt über 1000 Watt (rms) mit bis zu 3600 Watt Spitzenleistung. Durch das geschlossene Design spielt er äußerst präzise und trocken bis unter 20 Hertz. Der Subwoofer befindet sich abgesehen von einigen sehr feinen Kratzern auf der Oberfläche in neuwertigem Zustand. Er wurde in erster Linie zum Musikhören genutzt und ist nie auch nur ansatzweise ausgelastet worden. Ich gebe ihn nur ab, da er für meine Zwecke überdimensioniert ist. Aufgrund des hohen Gewichts (ca. 45 Kilo) ist nur eine Abholung in 48231 Warendorf möglich. Probehören ist nach Absprache selbstverständlich möglich. Das Abdeckgitter und Stromkabel werden mitgeliefert. Zudem sind die SVS Soundpath-Füße montiert, sie sind ebenfalls enthalten. Keine Garantie und keine Rücknahmen möglich!

    SVS SB-13 Ultra mit STA-1200D Upgrade-Kit Endstufe – sehr guter ZustandIch verkaufe meinen sehr guten SVS SB-13 Ultra Subwoofer. Er hat vor 2 Jahren eine neue Endstufe bekommen. Ich habe das Upgrade-Kit bei SVS gekauft. Die Endstufe hat 599€ gekostet. Seit dem Umzug vor über einem Jahr steht der Subwoofer nur herum und wird kaum noch benutzt. Die STA-1200D ist aus meiner Sicht hörbar besser zur alten STA-1000D Endstufe. Die Einstellung erfolgt nun per SVS APP einfach vom Sofa aus. Keiner muss mehr hinter den schweren Subwoofer kriechen und vom winzigen Display was ablesen. Die drei PEQs sind goldwert, wenn man auf den Klang Einfluss nehmen muss/ will, um den Bass an die Raumgegebenheiten anzupassen. Wischspuren vom Staubwischen sind vorhanden. Technische Daten zum Subwoofer sowie Test gibt es im Netzt viele. Bitte beim SB-13 Ultra sowie dem SB-4000 nachlesen. Der Subwoofer wiegt 45Kg. Ein Versand muss selbst organisiert werden. Es ist keine Verpackung vorhanden. Es wird eine Abholung empfohlen. Zahlung Bar bei Abholung. Kein PayPal erwünscht!
