Mint slightly used Sunfire XTQ 12 subwoofer. Have the microphone, all the accessories, the original box, has maybe 50 hours on it total. Sounds phenomenal. Read my feedback and buy with confidence.

I bought a used sunfire xteq8 to repair but I don’t have time to mess with it so I’m selling it in parts. This woofer works and moves good when hooked up to a amp. But to me it makes a slight wisp sound. It’s reading 4.6 on the meter.. Anyway some one might could fix it. Thanks

The rings are in very nice shape on the front side but the pegs on the back are broke. You can use 2 sided tape to hold it on and it works very well. That’s what I used. Thanks

The line includes three models that produce up to 3000W of crystal clear bass from 16-100Hz using diametrically opposing drivers, one active and one passive radiator. The 8-inch XTEQ8, 10-inch XTEQ10 and 12-inch XTEQ12 are housed in enclosures barely bigger than the size of the woofer diameter, with the XTEQ12 measuring just 13.5”(W) x 13.5”(H) x 13.5”(D). According to Core Brands Audio Marketing Manager Matt Dever, “Sunfire’s heritage is all about creating the foundation for an amazing home theater experience. The XTEQ series builds upon the advances pioneered with the Sunfire Atmos and TSEQ series subs. We pack more power and punch into a smaller subwoofer than any other manufacturer, and combine it with the innovation and superior performance that today’s luxury consumers demand.” The Sunfire XTEQ8, XTEQ10 and XTEQ12 subwoofers will retail for $1,500, $1,750 and $2,000, respectively. Each model leverages Sunfire’s exclusive Tracking Down Converter™ amplifier design. The drivers all feature the latest improvements of Sunfire’s renowned High Back-emf design, and to best accommodate the longer ‘throw’ of the XTEQ woofers, all feature Sunfire’s unique Asymmetrical Cardioid Surround design. The subs also leverage the latest in Sunfire’s auto equalization technology to tailor the subwoofer output to compensate for any room’s acoustic anomalies. Each model is built to be used in both 110-volt and 230-volt installations. Premium audiophile features include multiple turn-on options (auto audio sensing and 12 volt trigger activation), plus soft-clipping amplification, anti-walking treads, variable crossover and phase control. The XTEQ subwoofers include RCA line in/line out and slave connections making it easy to pair two subwoofers, with XLR connectors for pro applications. Integrators can perfect and dial in the sound for any room through continuously variable frequency and phase adjustments for both the low pass and high pass crossovers.
