Neo speakers are lighter, but a lot more expensive. That's why David dropped them from his offerings a while ago - price went up!

If we are talking about the DNA cabs, the only difference is the weight.
David designed the ceramic version in that way, that they sound like the neos.

There is a German webpage that explains the difference between the materials very good.

Hi RVBASS,

My understanding of the Neodymium magnets was/is that their performance properties were prone to decay prematurely. I recall when David came out with Neo speakers for Eden well after everyone else was using them. He didn't release any Eden Neo speakers until he believed he had not only achieved the standard Eden clarity of sound that he was looking for but also that they didn't decay prematurely with use. Evidently some Neo's specs degrade over time with usage. So it was a big deal when David brought out the Eden Neo speakers at a small premium over the ferrite magnets normally used in speakers.

There was a definite savings in weight with the Eden Neo's but it wasn't as much as you might expect because of the void-free plywood and the bracing used in Eden Cabs. They were both a little lighter and a little more expensive. Of course then the prices for Neo's went way up and they disappeared. It was great to see them in the DNS cabs for a while and with the DNS-112N the weight of the speaker magnet made a more evident weight savings. However, even with the ceramic magnets, the DNS-112 is about 4-lbs lighter than the earlier Eden cab and will handle significantly more power.

Actually, that was a bit of a rumor.
Both types don't loose there adhesive force that easy.

Good info as always Armin. Thanks for clearing that up and I promise not to spread any more rumors! ;)

Interesting to learn that storing ferrite and Neodymium together can cause them to demagnetize or change their polarity. Is that something we need to be careful of with speaker cabs (stacking regular and Neo speakers) or just how close do they need to be to have that effect?
