What is 4 cm tweeter?

A 4 cm tweeter is a type of speaker driver that is capable of producing high-frequency sound waves typically above 2,000 Hz. The size of the tweeter is measured in centimeters, with 4 cm being relatively small compared to larger tweeters. This size is commonly used in small bookshelf speakers, computer speakers, and car audio systems.

A tweeter plays a crucial role in reproducing high-frequency sounds, such as vocals, cymbal crashes, and other high-pitched instruments. A 4 cm tweeter can produce a good amount of detail and clarity in the high-frequency range, but may not be as robust as larger tweeters in terms of bass response and overall volume output.

One important consideration when selecting a tweeter is its sensitivity rating, which indicates how efficiently it converts electrical power into acoustic power. A higher sensitivity rating means the tweeter can produce more sound with less power input, which can be beneficial for achieving a louder and more dynamic sound.

Overall, a 4 cm tweeter can be a suitable choice for entry-level or smaller audio systems where space is limited, and a compact size is desired. However, for larger rooms or more demanding listening environments where higher volume output is necessary, a larger tweeter may be a better option.
