Physical difference

Alnico magnet, also known as AlNiCo is made from Aluminum, iron, nickel, and cobalt. They are quite strong but easily lose their magnetism. Comparing Alnico vs neodymium, Alnico has a better resistance against corrosion. Fender Bassman and Bandmaster used these Alnico speakers.

Some speakers come with end bells, others don’t. Alnico vs Ceramic speaker comparison shows, Alnico will compress at high volume, has a quicker breakup, and costs more. Why Alnico is so expensive? Since it is made from rare earth materials, this increases the cost.

They have the nature to magnetize rapidly or eliminate demagnetizing effects which result in outstanding performance. You can tune them easily as per your need. Alnico has smooth compression compared to Ceramic magnets, which is similar to that of tube amplifiers.

Ceramic or Ferrite magnets are made from strontium ferrite which is readily available. This reduces the cost of the Ceramic speakers. They don’t demagnetize or compress so quickly like the Alnico. There are several advantages of using a Ceramic speaker.

They can get louder than Alnico and can handle more amount of power. Ceramic speakers show smoother breakup and are quite heavier. It is around 3 times the weight of Alnico

How do you recognize Alnico drivers?

One major difference pops out if we compare Alnico vs Ferrite magnets, Alnico is a metal so it can conduct but, Ceramic can’t. this characteristic can help to recognize which one is Alnico and which one is Ceramic. You can use an ohmmeter and the one that conducts will be Alnico.

How do you recognize ceramic drivers?

Alnico speakers have a narrow shape and is much taller whereas, Ceramics are wider and shorter. Alnico tend to have the “horseshoe” on the back whereas ceramic have just a flat magnet on the back.

Alnico has a horseshoe or a bell-shaped back which you can see in the Jensen P12Q  and Jensen P12N  models respectively. The rear side of Ceramic is flat.

Tonal difference

Alnico vs Ceramic speakers, do they sound different? Absolutely. Alnico magnet speaker has a ‘chimey’ sound in the mid and high-frequency region. It sounds warm, smooth and pleasant but Ceramic sounds brighter. Alnico speaker tone is good for blues or mellow rock.

Ceramic magnets doesn’t show any compression which results in a clean and clear sound. Comparing, Ceramic vs Alnico speakers, Ceramic can deliver more accurate response. Ceramic speakers can get very loud without being distorted.

Comparing Alnico vs Ceramic vs Neodymium, Neodymium has similar characteristics as Alnico. Categorically, it falls between Alnico and Ceramic.

How I rated the Alnico vs Ceramic speaker products:

I rated the products after scrutinizing the details and focusing on crucial details.

Speaker size:

The Alnico or Ceramic magnet speakers are available is 10”, 12” or 15” sizes. The smaller size of a speaker can produce high frequencies better. So, if you choose a 10” the high-range of the spectrum will be more revealing.

Speaker sensitivity:

Speaker sensitivity of most of these alnico and ceramic magnets are above 95dB. The Celestion Ruby has a sensitivity of 100dB which means it can get very loud. If your application requires loudness, this will be ideal for you. However, loudness isn’t always better so you need to see the sensitivity of the speaker magnets before buying.

Power and impedance:

Each ceramic or vintage alnico speaker magnet indicates its impedance and how much power it can handle. You simply need to choose the right one and make sure the power rating is within the limit of the speaker and matches with the amp.

Cabinet:

The type of cabinet you are going to put the speaker magnet is important. It will affect the sound quality. the thickness should be 0.5” to ensure the it can stay stable.

While choosing a cabinet you will come across terms like open-back or closed-back. Guitar amp bodies that has a closed-back design ensure the bass response is better than open-backs.
