Ceramic Cone Speaker

Mechanical or thermal failure.

Ceramic cone speaker.

The fast speaker motor action allows the cones to generate micro cone fine granular distortion which has an alnico like magnet sound to it. This came with the nib cone as standard all through the 1960 s and never the pulsonics. Lower cost products got a less aggressive. The infinity team developed a laminated ceramic metal matrix diaphragm cmmd material that exhibits low mass high velocity and high damping.

Unfortunately the perfect driver does not exist in the real world so speaker designers select materials that allow them to get as close the ideal as possible. Goodmans would probably give you. The design of speaker drivers and then consequently loudspeaker boxes is the major part of our business and over the years we have driven this to some sort of perfection that attracts many of the leading speaker designers of the high end world. The material used to create a perfect speaker cone would need to be as stiff as steel light as a feather and able to start and stop on a dime.

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. The g10c is a 10 ceramic speaker with a 35 oz magnet and seamed cone. The speaker has the traditional ceramic crunch at the end of the cone incursion but is soften by the hemp cone s woody sonic texture. Green 4040 standard cone surround features a new ceramic magnet structure.

Elacs were a popular choice at the time but they are quite bright and chimy. Accuton manufactures loudspeaker drivers in germany. It boasts an extremely articulate top end with lows that are full and round but controlled. 10 alnicos are more difficult to find.

As for 10 speakers definitely try the 7442 model ceramic speaker. This video covers every step in the re coning of a 1957 jensen p10r alnico 5 speaker from the tweed vibrolux that was featured in a recent video series. Find them mostly in marshall gear. 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.

Mechanical failure occurs through over excursion of the cone which is when the cone moves too far beyond its limits to the point of damage due to excessive power or low frequencies beyond the cabinet s or speaker s ability. It is deep anodized aluminum where the anodizing ceramic penetrates up to 1 3 of the cone thickness.
