Measurement Service

How does it work?
	contact us (e-mail to info@klippel.de)
	we send you an order form and details
	you send the drivers and signed order form
	you receive results per e-mail

Sample Report

Instead of doing measurements yourself, you can send us the drivers, and we do the measurement for you.

Please contact us first (click "Request Order Form" above). You will receive details, pricing information, and a order form per e-mail or fax.

Fax the complete and signed order form before sending the drivers.

After the measurements are done, you receive the results via e-mail (see the sample report for how they look like)

We will return the drivers to you, depending on what you specify on the order form.

You can customize the measurement and analysis done for your drivers. The following services are provided:

Large Signal Mesurement
You will get a measurement report containing the large signal parameters (nonlinear, thermal, at the rest position), the state variables (displacement, temperature, ...) and the results of the distortion analysis. Based on this information you can assess the large signal performance (x-max, power compression, distortion) and can draw conclusions for practical improvements

Diagnostics
We give you support in the interpretation of Large Signal Measurement with suggestions for improvements and verbal analysis of the particular speaker.

Linear Identification
We identify the linear parameters including creep of mechanical suspension at three different amplitude levels

Prediction
We measure the fundamental, DC-component, harmonic distortion and most important intermodulation distortion in sound pressure and displacement versus amplitude and frequency. This information allows you assess the maximal output, stability of the driver (dc generation), and the distortion at a specified output.

Driver Simulation
Prediction of driver's behavior in acoustical system but considerung modified linear, nonlinear or thermal parameters specified by you. For example, you may switch off all but one nonlinearity to see the separated effect in the state variables or output. This simulation tells you about the dominant nonlinearities, their contribution to the total distortion, the cause of instabilities and the interaction between multiple nonlinear effects in the final application.

Consulting
Telephone or e-mail advice

Agreement Report
If you order a 3D-measurement and a driver prediction we provide you with an agreement report wherein the most important results of measurement and prediction are compared with each other.
