The audio signals that are electrical are converted into sound by a loudspeaker. Moreover, today the dynamic loudspeaker is the type of speaker widely used.  In the 1920's it was first built.

Different speakers types are available in the market. You may purchase the speaker to listen to music by connecting it to home theatre or in the car. This article will guide you about the difference in each of them.

Woofers, Crossovers, and Tweeters



They produce sounds of low-frequency with better audio quality. Woofer speakers size is large. Moreover,  a woofer which is good might be 12 inches or more in diameter. Speakers are normally small to produce high-frequency sound thereby ensuring audio quality which is good. Short wavelengths are present in high- frequency sounds. Thus, it can be reproduced well by small speakers.

A standard woofer is a slow vibrating speaker producing sound between 20 and 2,000 hertz (Hz). A mid-woofer has a range between 200Hz to 5000Hz. subwoofer focuses audio range, from 20 to 200 Hz. Lastly, in rotary subwoofer fan blades are used instead of cone and coil producing a sound below 20 Hz.


Different speakers are assigned a suitable frequency range by crossovers. There are two kinds of crossovers: Passive and Active crossovers.

Passive Crossovers

Unwanted frequencies are filtered out by these speakers by sitting between the amp and the speakers. Passive crossovers are built-in in some speakers. Thus, the advantage of this crossover is an easy installation.

Active Crossovers

Another name for active crossover is an electronic crossover. They are expensive and complex than passive crossovers. Moreover, power sources are required by active crossovers.


A high range of frequency is produced by tweeters. Thus, tweeters produce sound in the range of 2 kHz-20kHz. Moreover, some tweeters can produce sound at 100 kHz. The tweeters play out high frequencies. Moreover, the volume is low in tweeters as they are small.

Thus, these were some of the types of speaker.
