One Systems, Inc.

 Nashville, Tennessee - One Systems, Inc., was awarded patents by the United States Patent and Trademark Office for its innovative horn/driver and transducer designs, "Equivalent Throat Technology" and "Inside/Only Voice Coil" designs. Both patents are the result of design work by Mike O'Neill, One Systems' Chief Engineer. 

U.S. Patent No. 8,477,979 B2 includes the compression driver and horn structure used in One Systems' ET and ETS horn/driver designs. 

The novel and unique aspect of the Equivalent Throat system is that the driver produces wider dispersion and beamwidth than conventional drivers because the exit radius is coincident with its phase plug's summation plane. As a result, its smaller radius exit delivers wider dispersion. 

"Prior art for large format drivers / large exit diameters required either limited bandwidth or diffraction slots to achieve the desired "low-Q" response," explains O'Neill. "When this technology is incorporated into One Systems' products, they maintain excellent time domain response over a wide frequency range."

U.S. Patent No. 8,542,865 B2 includes the voice coil design utilized with One Systems woofers. The Inside/Only design disspitates heat continuously in any voice coil position, minimizes voice coil "rubs" as a source of reliability problems and also minimizes power compression. 

"The Inside/Only voice coil design ensures that our direct radiator designs provide high output and intelligibility from very compact enclosures," O'Neill continues. "Both of these technologies are the heart of One Systems' design philosophy and allows usto continue to be technology leaders in the industry."

One Systems President, Doug MacCallum concludes, "We continue to provide unique solutions for systems contractors, consultants and designers for applications all over the world."
