A speaker can produce sound even without an enclosure, so why do large speakers still need one? This article starts with rear-wave cancellation and explains the real acoustic purpose of a speaker enclosure.

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.

Can we judge a speaker’s sound quality just by looking at its frequency response curve? This article explains four common frequency response trends in a simple way to help beginners better understand speaker sound characteristics.
