Dayton Audio's WT3 makes measuring loudspeaker driver parameters easier, faster and more accurate than ever before. While previous generation woofer testers took around 6 minutes to measure 30 impedance points, the new WT3 measures over 30,000 data points in just a few seconds using a new swept sine technique that is only available with the WT3. The result is a very high-resolution impedance measurement that allows the extraction of an extremely accurate driver parameter set, suitable for the most critical loudspeaker design work. Free air parameters are measured in just a few seconds. VAS can be measured by traditional test box, added mass or, more conveniently, just by specifying the 1W/1m SPL of the driver. No other loudspeaker impedance tester is as fast, versatile or as easy to use as the WT3.
The primary application for WT3 will be testing raw drivers in order to gather the speaker parameters required for speaker design, but loudspeaker designers can also use WT3 to verify the resonance and Q of completed loudspeaker systems. You can even measure the 1 kHz inductance and 10 kHz inductance of your crossover inductors and the impedance response of complete multi-way loudspeaker systems.
