More Information


With more and more audio installations leaning toward a professional cinema experience, Sunfire XTEQ12 has met the demand for high performance subwoofers that focus purely on audio quality. Sunfire is proud to deliver accurate, powerful bass that spikes the entertainment value dramatically within every home. Delivering up to 3,000 watts of pure heart-thumping bass, you won’t find a more solid performer than the XTEQ series.

The beauty of XTEQ12 isn’t just in the sound. It’s the chic, compact design that blends into any room and pivots away from traditional gaudy, oversized equipment; instead making the audio the authority. Room-specific calibration accurately integrates an XTEQ subwoofer into any living space and existing audio system. You’ll get bone-rattling bass from some of the smallest subwoofer cabinets in the industry.

The big breakthrough features of the XTEQ12 is its proven tracking down converter amplifier, its long throw, high back-electromotive force drivers, and its fully automatic room equalizer. Taken together, these unique features provide these subwoofers with as much bass as you would get from several 15 inch drivers mounted in a cabinet the size of a small refrigerator. Defining the standard of quality today, the XTEQ series also brings a suite of premium audiophile features to the table, like advanced auto turn-on circuitry, Anti-Walking Tread Design Feet, gold plated connectors, soft clipping circuitry, and variable crossover level and phase control, making the XTEQ12 the foundation for any great home theater and audio system.

Tracking Downconverter Power Supply

Tracking Downconverter Power Supply

Sunfire's patented Tracking Downconverter power supply design dynamically adjusts the amplifier output to suit the incoming signal. On-demand power is therefore available for even the most demanding soundtracks, while its high efficiency keeps it upto 30% cooler than the competition.

Custom High Excursion Woofer

Custom High Excursion Woofer

Sunfire’s custom-designed 12” woofer handily outperforms every other similarly sized woofer in the world. Extremely high output, remarkable fidelity and superior control.

High Back-EMF Design

High Back-EMF Design

In 1996, Sunfire's engineers made a key discovery - that a woofers efficiency was directly proportional to its back electromotive force (emf). This lead to the development of Sunfire designed voice coils and oversized magnets that produce very high EMF and as a result, amazingly high output.
