When selecting a speaker driver, spec sheets can only get you so far; nothing replaces precision measurement.  This is why the DATS LA is a critical tool for any serious speaker builder.  With a built-in 100W amplifier, the DATS LA provides complete small and large T/S measurements in seconds, but it does much more than that.  Utilizing it’s patented DC-bias testing method, the DATS LA also reveals BL and KMS Symmetry in easy to read graphs, right in the software.  Other systems require careful calibration, training and a lot of time to test just a single driver.  The DATS LA will do all this in mere minutes.
