Tannoy still uses Alnico magnets in their top tier speakers....
Speaker magnets
Three questions:
1) The coil in a speaker when fed with current from the amplifier will produce its own magnetic field, presumably 4 layer coils more so. Over time does this ever have any effect on the characteristics of the speaker magnet?
2) Modern speakers have massive magnets compared with most vintage speakers. What advantage do they give a modern speaker over a vintage speaker?
3) Does the magnet in a speaker deteriorate to any noticeable amount just due to age?

I am led to believe that Tekton utilise this type of magnet in their TOTL Moab speakers.... https://happysouvenirs.com/en/products/souvenirs-fridge-magnet/ |
Hello, This is very interesting. I like to learn new things. When I was sixteen. I designed my own speaker and enclosure from Radio Shack and the lumber store. Stupid me I forgot to create a crossover. Also, it was not cheap to do at the time. I should have bought the book they sold. No internet at the time since this was 35 years ago. Live and learn. |
