Using WT3 to Measure a Woofers Parameters

Using WT3 to Measure a Woofer's Parameters

The basic steps to measure a driver's parameters are as follows. Before starting, be sure the unit has been calibrated.

•Start by connecting the WT3 hardware unit to a USB port on your PC.

•Next, launch the WT3 software.

•Make sure that the woofer is not connected to any other equipment and then connect the test leads of the WT3 unit to the terminals of the speaker under test.

•Raise the Windows volume control to maximum.

•Click the "Measure Free Air Parameters" button at the left side of the WT3 screen.

•You should hear the sweep from the speaker, the impedance is plotted and the parameters are displayed.

•Select a method to measure V(as), enter the required data and click on the "Measure V(as)" button.

After measuring a speaker you may want to enter additional information (say, the manufacturer and model of the speaker) at the Driver Editor. Then save the measurement to an empty memory. As an example, the keyboard sequence "Alt + 1" saves new data to memory 1.

Here is a typical measurement result:

WT3 specifications

The Dayton WT3 is a sophisticated and highly regarded tool in the field of audio measurement and analysis, particularly known for its precision in loudspeaker testing. This comprehensive device integrates several advanced features and technologies, making it an essential choice for audio professionals, engineers, and hobbyists alike.

One of the standout characteristics of the Dayton WT3 is its dual-channel capability, allowing users to conduct simultaneous measurements of two different loudspeakers. This feature is particularly useful in stereo systems where matching drivers is essential. The WT3 utilizes a high-resolution analog-to-digital converter (ADC) that ensures accurate and detailed frequency response measurements, providing users with the data they need to refine and optimize their audio setups.

The WT3 is equipped with a user-friendly interface that simplifies the measurement process. Its software is intuitive and runs on Windows, which means that users can easily navigate through various options to configure tests and analyze results. The inclusion of a built-in microphone makes it possible to perform room acoustics measurements, further enhancing its versatility.

Another key technology integrated into the Dayton WT3 is its frequency sweep capability. By generating continuous sine wave sweeps across a wide frequency range, the WT3 can analyze the response of loudspeakers in real-time. This allows for identifying resonances, distortion, and other critical parameters that affect sound quality.

The WT3 also features a range of measurement modes, including impedance measurements, which can be invaluable for understanding how a loudspeaker behaves across different frequencies. This data is displayed in easy-to-read graphs and charts, facilitating a straightforward interpretation of results.

Moreover, the Dayton WT3 utilizes advanced signal processing algorithms that help in reducing noise and other unwanted artifacts that can skew measurements. The device's accurate phase response measurement capability further distinguishes it from competitors, providing essential data for crossover design and speaker alignment.

In summary, the Dayton WT3 combines advanced measurement technology with an intuitive user experience, making it an essential tool for those seeking precise loudspeaker performance insights. Its features and capabilities position it as a valuable asset for both professional audio engineers and enthusiasts dedicated to achieving the best possible sound quality. Whether for designing new speakers or optimizing existing setups, the WT3 delivers reliable performance and accuracy.
