Disclaimer: Thiele/Small

The Thiele/Small parameters of a loudspeaker driver are measured under specific testing conditions, which may not accurately reflect the performance of the driver in all real-world situations. These parameters are typically measured in a laboratory setting, using specialized equipment and carefully controlled test conditions.

As such, the Thiele/Small parameters should be considered as a useful starting point for designing loudspeaker systems, but they may not accurately represent the behavior of the driver in all real-world scenarios. Factors such as enclosure design, room acoustics, and amplifier characteristics can all affect the performance of a loudspeaker driver.

It is important to note that the Thiele/Small parameters are not the only consideration when selecting a driver for a particular application. Other factors, such as power handling, frequency response, and distortion characteristics, should also be taken into account when designing a loudspeaker system.

Ultimately, the best way to evaluate the performance of a loudspeaker driver is to listen to it in a real-world setting, and to compare it with other drivers under similar conditions.
