Dayton Audio WT3 Woofer Tester Review

[admin]

The WT3 Woofer Tester by Dayton Audio is a fast, accurate and affordable measurement tool that’s about as easy to use as it gets. Just load the included software, plug the probe into the nearest USB port, calibrate, and you’re good to go. It’s that simple! It’ll measure driver impedance and derive the all-important Thiele/Small parameters - critical to the loudspeaker design process. It will also measure the impedance of various components commonly used in the construction of passive crossover networks such as resistors, caps & inductors. Rounding out this feature set, the WT3 sports some useful extra utilities you’ll likely find handy. All in all, this is one item likely to be a favorite of the DIY community for a long time to come.

Excellent, I was looking at that thing some time ago and I was wondering if it was any good.

Just as an FYI,

All of the volume levels for both audio out and record in should be at the max and the balance be set to the middle. If your settings are not these you will possibly see anomalies (i.e. strange spikes or dips, jagged plots, etc...) in the plot graphs.

Also in Vista on some systems the USB ports can be individually adjusted, so if you set it up on one port for testing and then the next day use a different port you may see anomalies in the measurements.

And as stated in the article there is a 90 second stabilization time for the unit, it is necessary to wait otherwise there will be anomalies in the test graphs.

And if you have it set up properly and calibrated and are getting strange graphs there could be two other causes:

1) Other noise in the testing area (i.e. kids, dogs barking, etc...) these things will affect the plot (testing should be done in a semi-quite room.

2) The .ini file became corrupted, just delete it and restart the WT3

Hope this helps.
