        The Dayton Audio DATS LA (Digital Audio Test System Loudspeaker Analyzer) represents the next evolution in loudspeaker measurement, integrating cutting-edge hardware and proprietary data analysis to deliver unprecedented insights into driver performance. Designed for engineers, speaker designers, and audio professionals, the DATS LA goes beyond standard impedance measurements, offering an advanced DC-biased analysis (U.S. Patent #11,272,301) that reveals critical non-linearities in motor force (Bl) and suspension compliance (Kms).

        With an integrated 100-watt AC/DC amplifier, precision impedance measurement, and advanced modeling capabilities, the DATS LA provides laboratory-grade analysis at a fraction of the cost of traditional industry standard test systems. Whether evaluating a driver’s small-signal behavior or large-signal limitations, this versatile system allows you to design, optimize, and validate loudspeakers with a level of detail previously inaccessible to most designers.

        DC-Biased Testing

        A Breakthrough in Loudspeaker Measurement

        DC Biased Impedance Measurement - U.S. Patent #11,272,301

        Traditional impedance-based testing methods provide valuable information about a driver’s small-signal characteristics but fail to capture how parameters shift with cone displacement. The DATS LA introduces an industry-first approach to this problem with its patented DC-biased measurement technique, enabling precise evaluation of a driver’s non-linear electromechanical behavior as a function of excursion.

        Using precisely controlled DC pulses to displace the voice coil and cone before performing impedance sweeps, DATS LA systematically captures the impact of excursion on key parameters. This results in highly accurate Bl(x) and Kms(x) curves, which illustrate motor and suspension symmetry across the driver’s operational range. By identifying non-linearities, mechanical limitations, and asymmetry, engineers can optimize motor structures, suspension designs, and excursion limits with unmatched precision.

        100W AC/DC Amplifier

        Real-World Large Signal Testing

        DATS LA - Peek at the 100 watt amplifier

        A major limitation of conventional speaker analysis systems is their inability to perform high-power measurements. The DATS LA’s integrated 100-watt amplifier overcomes this by enabling both small- and large-signal testing, allowing you to observe how T/S parameters evolve under realistic operating conditions. By increasing test signal voltage, you can evaluate how a driver’s parameters shift as it is driven outside its linear range, exposing critical performance metrics such as: 
        ✔ Motor force reduction due to flux modulation and coil offset
        ✔ Suspension stiffness variations impacting excursion limits
        ✔ Thermal compression and voice coil heating effects on resistance (Re) and sensitivity
        ✔ Bl degradation at higher outputs, limiting peak SPL capability

        With this information, designers can accurately model power compression effects, excursion limits, and distortion characteristics, ensuring their systems perform consistently across a wide range of SPLs.
