View Full Version : 077/2405: Alnico versus Ferrite?

All else being equal (phase plugs, diaphragms, resale value, collectibility, etc.) is the Alnico 2405 (or the 077) preferable to the later ferrite 2405H?

I was looking at at the product literature for the ferrite 2405H and as far as I can tell, there's no real difference in terms of performance.

Thanks.

And 077s were only Alnico, right?

Thanks.

077 was the home version of 2405, used for example in jubal and L300, both are alnico, but the 077 have blue diaphragm. 2405H is the ferrite version of 2405. I have both, (077 and 2405H) they measure very similar, 2405 is a little better, sound is another thing...

OK; thanks. I've fixed my post so the terminology now should be correct. I'm just trying to confirm that the motors of the 2405 and 2405H perform substantiallly the same.
