Sunfire Releases New Atmos Subwoofer


Sunfire_Atmos_subwoofer.jpgSunfire just announced that it will begin worldwide shipments on May 4 of its new Atmos subwoofer, reportedly the smallest most powerful subwoofer in its class.

The Atmos design incorporates dual custom designed 6.5" woofers in a sealed extruded aluminum enclosure that measures just over 8" tall. Utilizing a new proprietary asymmetrical cardioid surround, these drivers are capable of excursions of reportedly up to 1.8".

Resembling the variable thickness of the human heart, the cardioid surround provides allegedly superior linearity even at the furthest extension of the drivers. To achieve this new Sunfire standard for small-box, high-output performance, the extruded aluminum enclosure was engineered to withstand the increased backpressures that reach up to 24.4 PSI, or nearly two atmospheres of pressure, hence the name, "Atmos". Backpressure is required to maintain linearity over a long throw distance, allowing the small drivers to move substantial amounts of air.

To maximize bass output over a wider frequency range, Atmos utilizes a seventh generation cool-running 1400W amplifier featuring Sunfire's exclusive Tracking Downconverter technology, which provides the voltage and current necessary to create the driving force required to meet this new standard. Finite Element Analysis (FEA), a contemporary science, was used to design all elements of the Atmos, including the aluminum cabinet, the drivers and the next generation of the Tracking Downconverter amplifier.

Sunfire knows that every room is different, which is why the Atmos includes a microphone and auto-room equalizer circuit that is designed to automatically adjusts the subwoofer's response to best suit the room acoustics for maximum bass quality and performance. And for those thrill-seekers requiring even more bass, two Atmos subwoofers can be connected with a single wire using the master/slave set up. This allows both of the subwoofers to be equalized using one EQ point.

The Atmos has an MSRP of $2,000 and includes line-level unbalanced inputs, line-level outputs with high-pass or full range switch, a 12V DC input for remote turn on, 106 dB of output and a frequency response of 30Hz-100Hz.
