Ceramic Magnet Speaker

Ceramic is the cheapest and most common material.

Ceramic magnet speaker.

As the voice coil s effect lowers the available magnetic field of the alnico magnet the speaker becomes less efficient and the voice coil moves less.

Ceramic speakers are heavier because their magnet must be heavier to achieve the same power all other thing equal. 4 75 no cover 5 375 with cover cutout size.

The first crop of speakers in the early 1950s used alnico magnets which is why some people say they sound more vintage than speakers built with ceramic magnets. Alnico speaker breakup quicker that ceramic i. The permanent magnets used in speakers are called speaker magnets. Speakers with higher power ratings generally have larger magnets since the wire in the voice coil is a larger diameter is heavier and requires a larger magnet to get the magnetic energy required to get the heavier voice coil moving to achieve high frequency response.

They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet. Alnico speakers compress at high volumes.
