Sunfire - Little. Loud. Luxurious

For many, Sunfire means subwoofers. Little, loud and luxurious subwoofers. After all, that’s where we built our reputation. But the same unconventional thinking that spirits our subwoofer design drives the thinking behind our amps and theater speakers. Sunfire delights discerning listeners at every opportunity with hi-powered performance.

With 1400 Watts and a cabinet just 8″ inches tall, Atmos can put out enough power for most modern living spaces, and look stylishly diminutive too! For even more of the cleanest bass around, you can easily connect two Atmos subs with just one wire and go where few have dared to before.

It will leave the rational part of your brain fighting for its life.

The Sunfire Atmos Subwoofer is designed to give you the best possible low-frequency sound quality for your Home Theater experience. It incorporates a tremendously powerful 1400 Watt built-in amplifier and a pair of drivers to produce tight, floor-rumbling, denture-rattling bass that you can feel as well as hear.

The Atmos subwoofer has an automatic equalization system which will tailor the subwoofer output to compensate for any room effects. Great bass performance through thick and thin. The role of any Surround is to keep the woofer on the straight and narrow as it moves back and forth. The straighter the woofer — the better the fidelity. To best accommodate the longer ‘throw’ of the Atmos woofer, Sunfire engineers designed a unique Asymmetrical Cardiod Surround. The ACS got its name because of the varying thickness of the wall of the surround from one side to the other. So what does this all mean to you? It means the ACS allows up to 1.8″ inches of ‘throw’ with tight, well defined bass that combines extreme output with very low distortion and a quality of sound that is unique to Atmos. Another state-of-the-art advancement artfully executed and timelessly designed.
