Rockport Technologies began as Payor Acoustics Inc. in 1984 with the design of a compact, satellite/subwoofer loudspeaker system. Long ago we recognized that the two areas of greatest loss in an analog reproduction chain are where the transduction occurs from mechanical to electrical energy at the front end, and then back to mechanical (acoustical) energy at the loudspeaker. Consequently, these two transduction sites provide the greatest opportunity for improvement in an audio system, and have been the areas where we have focused our attention for more than 25 years.
