What do the 5 W, 10 W, or 20 W ratings on a speaker really mean? Rated power represents the power a speaker can handle continuously under specified test conditions, while maximum power indicates its ability to withstand short-term signal peaks. Understanding the difference helps us read speaker specifications correctly.

White noise and pink noise contain different frequency components and can be used to simulate the complex sound signals that speakers may encounter in real applications. Through noise testing, we can evaluate a speaker’s durability, rated noise power, and reliability when handling instantaneous peaks.

Why are tweeters often designed with spherical or dome-shaped diaphragms?
This is not just for appearance. It is closely related to voice coil placement, heat dissipation, high-frequency efficiency, and sound radiation.
However, dome-shaped diaphragms may also introduce issues such as reflection, standing waves, and off-axis attenuation.
This article explains the basic acoustic principles and design trade-offs behind dome tweeters in a simple way.
