(Nasdaq:ATCO) today announced PureBass, a new, patent-pending, extended range sub-woofer technology that improves performance while reducing the cost of subwoofer/satellite systems. PureBass is the optimum complement to ATC's Stratified Field(TM) (SFT(TM)), and Planar Magnetic(TM) speaker technologies. The company is marketing PureBass to OEM manufacturers and prospective licensees for a wide variety of consumer applications where superior low frequency performance and seamless compatibility is desired for use with high quality home audio systems including Home Theater and Hi-Fi subwoofer/satellite speaker applications. PureBass offers the same advantages when used in car stereos, in-wall, and custom home installations. The new technology minimizes distortion, produces greater output capability, and reduces system costs when compared to conventional woofer systems. It also provides a unique interface with any upper range satellite speaker system, and is ideally suited for seamless integration with the company's high performance, SFT and Planar Magnetic thin-film speaker technologies. Delivery of samples to prospective PureBass licensees is in process. The company expects to license PureBass to multiple licensees this year. The company will also market its patent-pending Magnified Force Woofer (MFW) sub-woofer technology for high-end applications, professional installation, and special events venue needs. Bob Todrank, V.P. of sales, marketing, & business development for ATC, said, "PureBass is a breakthrough in sub-woofer technology, allowing lower-cost development and manufacturing for a variety of consumer products including Hi-Fi and Home Theater. The unique, patent-pending design of PureBass is the first cone-based sub-woofer technology that has low enough distortion to integrate seamlessly with highly accurate thin-panel speaker systems." He continued, "PureBass is a unique offering in the audio field allowing increased design flexibility and increased alignment options when used in conjunction with any upper range satellite speakers. Besides its performance advantages and ideal matching to our high performance thin-film systems, it also allows our licensees to improve the performance and significantly reduce the cost of their conventional satellite speaker systems when used with PureBass. Greater output, reduced size, higher reliability, lower distortion, and reduced system cost make this a desirable technology for many of our prospective licensees." The company also announced that it has received two additional patents on its HyperSonic(TM) Sound(HSS(TM)) technology, (Patent No.'s 6,108,427 and 6,108,433) increasing the total number of Hypersonic Sound patents owned by ATC to 9 with many more pending in the United States and internationally. HyperSonic Sound is a revolutionary sound reproduction system developed and owned by American Technology Corp. The most important quality of HSS is the ability to direct or focus sound into a tight beam, similar to the beam of light from a flashlight. Not since the development of the "cone" loudspeaker more than 75 years ago has any technology provided such a significant departure from conventional speakers and such a remarkable approach to the reproduction of sound. About American Technology Corp. American Technology is shaping the future of sound by developing and licensing its patented and patents-pending technology portfolio which includes: the award-winning HSS(TM) (HyperSonic(TM) Sound Technology); SFT(TM) (Stratified Field(TM) Technology); Planar Magnetic(TM); MFW(TM) (Magnified Force(TM) Woofer); PureBass(TM) Sub-Woofer Technology; and FM Sounds(TM) consumer radio products.
