What is Speaker Laser Characterization and Why Do I Need It?


DSM Laser Characterization

As the final verification step to move from design to production using DSM, we strongly suggest you send us 3 to 5 speakers for precision characterization under our proprietary laser measurement system. The purchase of an evaluation kit entitles you to a single, free speaker laser characterization (one per kit). Claim your free characterization using the 12-character submission code affixed to the bottom of the kit.

To submit speakers for characterization, use the link below. Please note: this step is only required for your final speaker and enclosure design.
