Don't wait! For a limited time we've bundled the popular Dayton Audio WT3 driver testing system with a precision scale that perfectly complements the WT3 when calculating Vas using the Delta Mass method! This highly accurate digital scale is a $30 retail value and accurate to 0.005 of a troy ounce! Order a WT3 today and start testing your drivers using the most affordable speaker analysis test device available, and get a FREE scale! Dayton Audio's WT3 makes measuring loudspeaker parameters faster and more accurate than ever before. Previous generation woofer testers took around 6 minutes to measure 30 impedance points, while the new WT3 measures over 30,000 data points in a few seconds using an exclusive swept sine technique. The result is a high-resolution impedance measurement that allows the extraction of extremely accurate driver parameters. Free air resonance may be measured in a few seconds. VAS can be measured by traditional test box, added mass or by specifying the 1W/1m SPL of the driver. No other loudspeaker impedance tester is as fast or as easy to use! WT3 hardware consists of a tiny USB interface device with cable and alligator leads. Windows-based software provides an easy-to-use interface that allows you to be testing very quickly. You can save as many as 20 impedance measurements per project and then overlay and compare measurements to create a custom report. Ideal for speaker QC.

For a limited time, bundled with a FREE scale! A $30 value!
Measure speaker parameters of any driver, large or small
Compact USB interface with molded test leads
Data can be printed or saved to create a driver parameter library
Parameters can be exported to WinSpeakerz and other popular box design programs
Measures VAS using added mass, test box, or SPL method
Straightforward, easy-to-use measurement software
Manufactured on state-of-the-art equipment using surface mount components

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 of your crossover inductors and the impedance response of complete multi-way loudspeaker systems.

Minimum System Requirements:

IBM PC or compatible system with 64MB RAM
500 MHz Pentium III processor
MS Windows 98, Me, NT, 2000, XP, or Vista
