If you are building a speaker, why waste your valuable time calculating "optimum" enclosures that are based on specs that can vary by as much as 30%? With the Woofer Tester 2, you can accurately measure the parameters of your specific drivers from the comfort of your own home. The complete process takes just a few minutes, and provides easy-to-read results that you can print and save. But it's not just for woofers-- the WT2 accurately measures impedance and phase from 1Hz - 20kHz, allowing it to measure midranges, tweeters, inductors, crossovers, and even speaker cables.
