The Linear Array Transducer (LAT) is a loudspeaker technology using multiple opposed interleaved diaphragms to create a bass transducer with a cylindrical form factor and almost no mechanical vibration. Construction and operating principles are described. Equivalent circuit diagrams are provided and frequency response and impedance measurements are shown. Recent structural improvements in the LAT are also discussed. System (box) design considerations are discussed and examples of its use in a product are shown.
