THE BEST TOOL FOR SPEAKER BUILDERS

DATS V3 Computer Based Audio Component Test System:

   
   
   

I use this when constructing speakers, as it can make precise measurements of all the necessary data for speaker units, capacitors, coils and resistors.

Thiele/Small Parameter Measurement
Quickly and accurately measure a drivers T/S parameters. Just attach the test leads directly to a drivers terminals and click "Measure Free-Air Parameters" and the impedance magnitude will be displayed on the graph along with the measured Re, Fs, Qts, Qes, Qms, and Le. Next add mass to the cone or mount the driver in a suitable test box and click "Measure V(as)" to derive the mechanical parameters such as Vas and Mms.

Enclosure Tuning Verification
Once your driver is mounted in an enclosure DATS V3 makes it easy to verify your systems overall tuning for vented enclosures or Q for sealed enclosures by using the "Measure Free Air Parameters" button. The system will run a quick sweep and plot the impedance magnitude making it easy to verify the actual tuning of your system.

Verify Crossover Wiring and Performance
Once your speaker system is complete, you can run an "Impedance Sweep" to plot the overall system impedance. A quick comparison of the measured impedance to your modeled impedance makes it easy to ensure that your crossover is wired correctly and performing as intended.

Inductor Measurement
Measure a both the inductance and DC resistance of a coil with just one click. The DATS V3 is accurate from 0.05 mH up to 100 mH.

Capacitor Measurement
As a capacitance meter DATS V3 is in a league of its own. In seconds, it will measure all of a capacitors electrical characteristics including capacitance, equivalent series resistance, Q, and even loss angle. DATS V3 is capable of accurately measure capacitance from 0.002 uF to 10,000 uF.

Resistor Measurement
Naturally, DATS V3 is also perfect for measuring resistance. As a unique feature, it will also plot the impedance of a resistor allowing you to see just how non-inductive your resistors really are. Resistance measurements are accurate from 0.002 ohms up to 10,000 ohms.
